show pppoe throttled mac Command

timing wink-duration Command

vlan ifdescr detail Command

VRF Aware System Message Logging (Syslog)

isis metric and isis ipv6 metric Commands

The maximum keyword has been added to the isis metric and isis ipv6 metric commands so that you can set the Intermediate System-to-Intermediate System (IS-IS) metric to the maximum link metric. Entering the maximum keyword excludes the link from the SPF calculation. If a link is advertised with the maximum link metric, the link is not considered during the normal SPF calculation. When the link is excluded from the SPF, it is not advertised for calculating the normal SPF. An example is a link that is available for traffic engineering, but not for hop-by-hop routing.

For the isis metric command, the maximum keyword is available under the subinterface configuration mode.

For more details regarding the maximum keyword for the isis metric command, see the "IS-IS Commands" chapter of the Cisco IOS Routing Protocols Command Reference at the following URL:

http://www.cisco.com/en/US/docs/ios/iproute_isis/command/reference/irs_is1.html

For more details regarding the maximum keyword for the isis ipv6 metric command, see the Cisco IOS IPv6 Command Reference at the following URL:

http://www.cisco.com/en/US/docs/ios/ipv6/command/reference/ipv6_09.html

show pppoe throttled mac Command

The show pppoe throttled mac command displays information about MAC addresses from which PPP over Ethernet (PPPoE) sessions are throttled, that is, not currently accepted. PPPoE connection throttling limits the number of PPPoE session requests that can be made from a MAC address within a specified period of time. Use the show pppoe throttled mac command to display MAC addresses and ingress ports of users that exceed connection throttling limits that you configured using the sessions throttle command.

The following is sample output from the show pppoe throttled mac command:

Router# show pppoe throttled mac

MAC(s) throttled

MAC Ingress Port

00c1.00aa.006c ATM1/0/0.101

00a4.0088.00b5 ATM1/0/0.101

timing wink-duration Command

The timing wink-duration command has been enhanced with the addition of the receive keyword and minimum and maximum arguments. You can specify the timing range for a receive wink-signal duration for a voice port. The syntax for this command is as follows:

timing wink-duration {time | receive minimum maximum}

vlan ifdescr detail Command

The vlan ifdescr detail command displays details of the VLAN interfaces. When vlan ifdescr detail is configured and a new encapsulation dot1q is configured, you see the detail description. The getmany command output displays the interface and subinterface. If the router is reloaded saving the configuration, all subinterfaces appear in the detail output.

The following example shows how to enable the display of interface and subinterface details:

Router# vlan ifdescr detail

interface e0/0.1

encapsulation dot1q 100

interface eo/0.2

encapsulation dot1Q 200

The following is sample output from the getmany command:

Additional Baud Rates for Serial CEM Network Module

Gigabit EtherChannel

Additional Baud Rates for Serial CEM Network Module

On a Serial CEM Network Module, you can now use the clock rate (interface serial) command to set additional baud rates of 300, 600, 1792K, and 1920K bps. The new values are documented at the following URL:

http://www.cisco.com/en/US/docs/ios/12_3t/12_3t7/feature/guide/bbfeamod.html

Gigabit EtherChannel

Gigabit EtherChannel (GEC) allows gigabit per second transmission rates and provides flexible, scalable bandwidth with resiliency and load sharing across links for switches, router interfaces, and servers. GEC combines multiple physical Gigabit Ethernet links into one channel, which manages load sharing of traffic among the links in the channel as well as redundancy if one or more links in the channel should fail; Unicast, broadcast, and multicast traffic is distributed across the links, providing higher performance and redundant parallel paths. If a link fails, traffic is redirected to remaining links within the EtherChannel without user intervention.

Based on the functionality, the GEC is the same as the Fast EtherChannel (FEC) except for the following:

The interfaces added to the channel are Gigabit Ethernet interfaces.

Because the onboard Gigabit Ethernet supports jumbo frames, there is a difference in the range of the MTU supported.

On the Cisco 7200, native (onboard) Gigabit Ethernet supports jumbo frames. The maximum transmission unit (MTU) supported on native Gigabit Ethernet ports is 9216. By default, the EtherChannel takes an MTU size in the range of 1500 to 10240 bytes. Once the first interface is added to the channel and an MTU is configured on it, the MTU range of the EtherChannel changes from its default value to the range supported by the first interface added to the channel.

For detailed information about this feature, see the following document:

http://www.cisco.com/en/US/docs/ios/12_0s/feature/guide/sel_drop.html

ACL—Named ACL Support for Noncontiguous Ports on an Access Control Entry

For detailed information about this feature, see the following document:

http://www.cisco.com/en/US/docs/ios/12_3t/12_3t7/feature/guide/gtaclace.html

ACL Performance Enhancement

An IP access control list (ACL) is a Cisco IOS software feature that allows an administrator to configure a network to permit and deny packets based on a set of ACL entries, thus improving security and control within a network. These lists contain entries that are searched sequentially for matches among certain fields in Layer 3 and Layer 4 packet headers.

Before Cisco IOS Release 12.3(2)T, ACL entries were sequentially configured and stored. This implementation caused the first match in a search to be the first ACL entry in a given list, not the entry that provided the best match. Although this implementation was straightforward and logical, it did not scale well with the number of ACL entries in an ACL.

Cisco IOS Release 12.3(2)T implements ACLs using hierarchical radix tries (sometimes called multilevel tries, backtracking tries, or tries-of-tries) to improve matching performance. Individual tries are made for the source prefix and the destination prefix, with additional ACL entry information such as TCP ports, TCP flags, and time ranges being held at the nodes. Cisco IOS software performs a best match lookup for the given set of prefixes. This new implementation is an internal improvement that supports all existing functionality, and the sequential searching properties that cause ACLs to check the entries from start to end and stop searching for a match as soon as one is found are still valid.

The benefits of implementing of ACLs using hierarchical radix tries are as follows:

Memory usage is made more efficient.

Less system resources are required to maintain the tries information.

Performance of ACL matching is improved for larger access lists.

ACL Support for Filtering IP Options

For detailed information about this feature, see the following document:

Administrative Secure Device Provisioning Introducer

This feature was introduced in Cisco IOS Release 12.3(8)T. For detailed information about changes and enhancements to this feature in Cisco IOS Release 12.3(14)T, see the following document:

http://www.cisco.com/en/US/docs/ios/12_3t/12_3t14/feature/guide/gtadintr.html

Advanced Encryption Standard (AES)

The Advanced Encryption Standard (AES) feature adds support for the new encryption standard AES, with cipher block chaining (CBC) mode, to IP Security (IPSec). AES is a privacy transform for IPSec and Internet Key Exchange (IKE) that has been developed to replace the Data Encryption Standard (DES). AES is designed to be more secure than DES: AES offers a larger key size, while ensuring that the only known approach to decrypt a message is for an intruder to try every possible key. AES has a variable key length—the algorithm can specify a 128-bit key (the default), a 192-bit key, or a 256-bit key.

For more details on this feature, see the following URL:

http://www.cisco.com/en/US/docs/ios/12_2t/12_2t13/feature/guide/ft_aes.html

Analog Centralized Automatic Message Accounting (CAMA) E911 Trunk

The Cisco 1751 and Cisco 1760 routers now support analog centralized automatic message accounting (CAMA) trunks on the two- and four-port Foreign Exchange Office (FXO) cards. The VIC2-2FXO and VIC2-4FXO cards are now user configurable for CAMA mode operation on a port-by-port basis. For example, on the VIC2-2FXO card, port 0 can be configured for CAMA, and port 1 can be configured for FXO-M1 operation.

The CAMA feature offers the following benefits:

Direct connection to the E911 network

Compliance with current legislation requiring enterprises to connect directly to the E911 network

Trunk capabilities to emergency services that are not currently supported on any Cisco product

Configuration on H.323 Voice over IP (VoIP)

Any Transport over MPLS (AToM) SCR VC Mode for PA-A3-T1/E1-IMA

You can configure AToM ATM Single Cell Relay (VC mode) on the following port adapters: PA-A3-8T1IMA and PA-A3-8E1IMA.

Blinking LEDs to Indicate DSL Line Training

The ADSL LED Blinking feature provides information on the status of a DSL line. ADSL Tx/Rx is used for this purpose. There are three distinct blinking patterns that indicate the various states of a DSL line when it is training.

1. When the firmware is being downloaded within the router, the LED remains on for 700 ms and goes off for 300 ms.

2. When the modem state is MODEM_ACT_ACK (0x8), the router is waiting to hear from the central office (CO) and is not yet seeing an incoming signal. During this time, the LED will be on and off for 50 ms each.

3. When the modem state is MODEM_TRAINING (0x10), the LED will always be on. This means that the DSL line is training.

Shortly after the DSL line has started training, the modem state changes to SHOWTIME, and then the router is successfully trained with the DSLAM.


Note The CD LED on the front panel will be off during the DSL line training process. This is different from the normal operation when packets are being transmitted or received.

Call Failure Recovery (Rotary) on the Cisco Multiservice IP-to-IP Gateway

The Call Failure Recovery feature eliminates the need for identical codec capabilities for all dial peers in the rotary group and allows the IP-to-IP gateway to restart the codec negotiation process with the originating endpoint on the basis of the codec capabilities of the next dial peer in the rotary group.

For detailed information about this feature, see the Cisco Multiservice IP-to-IP Gateway Application Guide at the following URL:

http://www.cisco.com/en/US/partner/docs/ios/voice/cube/configuration/guide/vb-gw-roadmap.html

Call Routing Enhancements to the H.323 Gatekeeper and GKTMP (GK API)

These features improve routing flexibility in customer networks in which an external route server is used to select potential endpoints for call completion.

Nonblocking GKTMP (GK API): Timing changes are associated with recovery processing when socket errors occur.

Separate DNIS for Alternate Endpoints: It is now possible to associate a unique DNIS with each alternate endpoint.

Support for "z" Tag in RESPONSE xRQ: This support enhances the responses that a route server can provide to the H.323 gatekeeper to allow greater flexibility for combinations of gateway endpoints and gatekeepers.

Calling Line Identification for Spain and Austria

Caller ID (sometimes called CLID or ICLID for incoming call line identification) is an analog service offered by a central office (CO), that supplies calling party information to subscribers. Typically, the calling party number, and sometimes the name, appears on a station (also called extension) device such as a PC telephony software application screen or the display on a telephone. Type 1 Caller ID show the calling party information while the call is ringing, and Type 2 Caller ID shows the calling number display while the recipient is on another call. Type 1 Caller ID is supported in this release.

The Caller ID feature supports the sending of calling party information from Foreign Exchange Station (FXS) loop-start and ground-start ports into a Caller-ID-equipped telephone device. The FXS port emulates the extension interface of a PBX or the subscriber interface for a CO switch.

Spain and Austria both use the ETSI-FSK method for sending the caller number to the analog phone.

The following is a list of Cisco IOS voice features that have been introduced in various Cisco IOS releases and that are now supported on the Cisco 1700 series platforms as part of Cisco IOS Release 12.3(11)T.

The following Cisco IOS VoIP features are supported on the Cisco 1700 series platforms for Cisco IOS Release 12.3(11)T:

H.323v4: Enhanced Call Usage Reporting

H.323v4 Gateway Zone Prefix Registration Enhancements

SIP Call Transfer and Call Forwarding

VoIP and Cisco Express Forwarding (CEF) Interoperability

VoIP and Policy Based Routing (PBR) Interoperability

H.323v4: Enhanced Call Usage Reporting

This feature provides H.323v4 enhancements that provide standards-based call usage reporting to the gatekeeper from an H.323 gateway. This information is used by the gatekeeper to generate call detail records (CDRs).

For more information, see the following documents:

The "Cisco IOS Call Control Technology" section in the Cisco IOS Voice Configuration Library:

http://www.cisco.com/en/US/docs/ios/12_2t/12_2t11/feature/guide/ftgkrenb.html

H.323v4 Gateway Zone Prefix Registration Enhancements

This feature provides support for two capabilities included in H.323, version 4: additive registration and dynamic zone prefix registration. Additive registration allows a gateway to add to or modify a list of aliases contained in a previous registration without first unregistering from the gatekeeper. Dynamic zone prefix registration allows a gateway to register actual PSTN destinations served by the gateway with its gatekeeper.

For more information, see the following documents:

http://www.cisco.com/en/US/docs/ios/12_2t/12_2t15/feature/guide/ftgwzpre.html

SIP Call Transfer and Call Forwarding

This feature introduces the ability of Session Initiation Protocol (SIP) gateways to initiate blind or attended call transfers. Release Link Trunking (RLT) functionality is also added. With RLT, SIP blind call transfers can now be triggered by channel-associated signaling (CAS) trunk signaling. This feature also implements SIP support of call forwarding requests from a Cisco IOS gateway.

For more information, see the Cisco IOS SIP Configuration Guide:

http://www.cisco.com/en/US/docs/ios/voice/sip/configuration/guide/12_4t/sip_12_4t_book.html

VoIP and Cisco Express Forwarding (CEF) Interoperability

This functionality enables Cisco Express Forwarding of VoIP signaling and payload packets that originate from voice interfaces and interactive voice response (IVR) applications.

This feature modifies the Voice over IP (VoIP) and IVR programming so that they can interoperate with features that are supported only in the CEF path (not in the fast-switching path that VoX uses). Voice and IVR work only in the fast path on the routers where they are originated and terminated (voice and IVR on "transit" routers are just data packets and of course can be CEF-switched).

This feature enables policy-based routing of VoIP traffic that originates or terminates on the specified voice gateways and introduces voice packet differentiated services code point (DSCP) marking for Media Gateway Control Protocol (MGCP) voice gateways.

For more information, see the VoIP Interoperability with Cisco Express Forwarding and Policy-Based Routing document:

http://www.cisco.com/en/US/docs/ios/12_3/vvf_c/cisco_ios_voice_configuration_library_glossary/vclcef.html

VoIP and Policy Based Routing (PBR) Interoperability

PBR gives you a flexible means of routing packets by allowing you to configure a defined policy for traffic flows, lessening reliance on routes derived from routing protocols. To this end, PBR gives you more control over routing by extending and complementing the existing mechanisms provided by routing protocols. PBR allows you to set the IP precedence. It also allows you to specify a path for certain traffic, such as priority traffic over a high-cost link.

PBR allows you to perform the following tasks:

Classify traffic according to extended access list criteria. Access lists, then, establish the match criteria.

Set IP precedence bits, giving the network the ability to enable differentiated classes of service.

Route packets to specific traffic-engineered paths; you might need to route them to allow a specific QoS through the network.

For more information, see the VoIP Interoperability with Cisco Express Forwarding and Policy-Based Routing document:

http://www.cisco.com/en/US/docs/ios/12_3/vvf_c/cisco_ios_voice_configuration_library_glossary/vclcef.html

http://www.cisco.com/en/US/docs/ios/12_3/12_3x/12_3xy/archive/gtcmm.html

Cisco Conferencing and Transcoding for Voice Gateway Routers

The Cisco Conferencing and Transcoding for Voice Gateway Routers feature enables voice conferencing among conferees at small, remote branch offices or distributed sites using local resources, without calls having to traverse the company WAN to the central site that supports such services.

The feature also provides transcoding at the remote site. Different IP telephony devices support different codecs, and, for communications to be enabled between them, transcoding is required. The feature provides transcoding at the remote site, without having to access transcoding services at the central site.

To provide these services, the feature takes advantage of unused DSP resources on a network module in an already existing small or midsize Cisco router at the remote site. The collection of DSP resources so made available is called a DSP farm. The DSP farm is managed at a central office or branch office by Cisco CallManager, the software-based call-processing component of the Cisco IP telephony solution.

The Cisco Conferencing and Transcoding for Voice Gateway Routers feature was originally supported in Cisco IOS Release 12.2(13)T. This feature is now supported on the Cisco Catalyst 4000 Access Gateway Module (AGM). See the following document for additional information:

With this enhancement, customers can now use the set command to configure packet marking actions in the child classes as well as in the parent classes of a hierarchical policy map.

For more information about class-based packet marking, see the "Classification" part of the Cisco IOS Quality of Service Solutions Configuration Guide.

For more information about the set command, see the Cisco IOS Quality of Service Solutions Command Reference, Cisco IOS Release 12.3T.

Class-Based QoS MIB (CBQoSMIB)

The Class-Based Quality of Service Management Information Base (CBQoS MIB) provides access to quality of service (QoS) configuration information and statistics. The CBQoS MIB allows service providers to monitor their QoS offerings. This MIB gives router QoS configuration such as ClassMap, PolicyMap, Match Statements, and Feature Actions configuration parameters. The MIB also contains counter objects that give statistics such as the number of packets traversed conforming to a policing feature. The MIB uses several indexes to identify QoS features and to distinguish among instances of those features. The MIB provides information about marking and policing done using IP precedence and differentiated services code point (DSCP).

Class-Based QoS MIB (CBQoSMIB) Enhancements

This feature enhances the Class-Based Quality of Service (QoS) MIB (CBQoSMIB) in Cisco IOS software. For information about the CBQoSMIB and to locate and download MIBs for selected platforms, Cisco IOS releases, and feature sets, use Cisco MIB Locator found at the following URL:

http://tools.cisco.com/ITDIT/MIBS/servlet/index

Class-Based QoS MIB (CBQoSMIB) Enhancements III

Several MIB objects and tables have been added to the CBQoSMIB to reflect the enhanced functionality of the modular QoS CLI (MQC). These MIB objects and tables provide enhanced traffic policing, shaping, and marking functionality.

The following MIB objects and tables were added to the CBQoSMIB:

Two time-based MIB objects, burst ms and excess burst ms, used when you are configuring traffic policing.

These parameters were added to allow you to specify the appropriate burst values to be used for policing traffic. However, these two parameters can be used when you are configuring traffic policing on the basis of a percentage of bandwidth only.

For more information about configuring traffic policing on the basis of a percentage of bandwidth, see the Percentage-Based Policing and Shaping feature at the following URL:

http://www.cisco.com/en/US/docs/ios/12_2t/12_2t13/feature/guide/ftpctpol.html

Two time-based MIB objects, sustained burst size in ms and excess burst size in ms, used when you are configuring traffic shaping.

These parameters were added to allow you to specify the appropriate burst values to be used for shaping traffic. However, these parameters can be used when you are configuring traffic shaping (either average-rate traffic shaping or peak-rate traffic shaping) on the basis of a percentage of bandwidth only.


Note The sustained burst size in ms and excess burst size in ms objects are not currently supported on the Cisco 7500 series router. Therefore, on the Cisco 7500 series router, the counters for these two MIB objects will display zeros.


For more information about configuring traffic shaping on the basis of a percentage of bandwidth, see the Percentage-Based Policing and Shaping feature at the following URL:

http://www.cisco.com/en/US/docs/ios/12_2t/12_2t13/feature/guide/ftpctpol.html

One table used to count statistical data associated with the various set commands available in Cisco IOS software.

For more information about the Cisco IOS set commands, see the Cisco command reference publications for the Cisco IOS release that you are using.

Three tables used to support the Enhanced Packet Marking feature available with Cisco IOS Release 12.2(13)T.

For more information about the Enhanced Packet Marking feature, see the following URL:

http://www.cisco.com/en/US/docs/ios/12_2t/12_2t13/feature/guide/ftenpkmk.html

Class-Based Traffic Policing with CLP Tagging

When configured on the router, the Class-Based Traffic Policing with CLP Tagging feature polices the flow of cells in the forward (into the network) direction of a virtual connection. The traffic policing mechanism determines whether received cells comply with the negotiated traffic management values and tags the cell with a CLP bit value of 1. The purpose of this feature is to mark traffic that does not meet the traffic management values so that packets that exceed the set values can be dropped by the network if the network is congested.

Distributed Dial-on-Demand Routing

In previous Cisco IOS software releases, distributed Cisco Express Forwarding (dCEF) is not supported for dialer interfaces on the Cisco 7500 series router. The Distributed Dial-on-Demand Routing (DDR) feature introduces the ability for the Cisco 7500 series router to perform dCEF switching on dialer interfaces. dCEF switching increases the performance of the router by moving processing from the Route Processor (RP) to the line card (LC).

The Distributed DDR feature can be used with all current dialer configurations—dialer profile interfaces, legacy dialer interfaces, and Multilink PPP on dialer interfaces. All pool members of the dialer interface must share the same Versatile Interface Processor (VIP) and the same type of port adaptor (PA). Quality of service (QoS) is not currently supported for the Distributed DDR feature. A VIP2-50 or higher is recommended for running the Distributed DDR feature.

No configuration commands are required to enable the Distributed DDR feature; however dCEF must be enabled. If dCEF is not enabled, processing will occur on the RP as it would in previous releases of Cisco IOS software that lack the Distributed DDR feature. The Distributed DDR feature can be disabled by globally disabling dCEF or by configuring the no ip route-cache distributed command on the dialer interface or D-channel interface.

Distributed Multilink Frame Relay (FRF.16)

DNS Proxy

In Virtual Private Network (VPN) or PPP over Ethernet (PPPoE) scenarios, the router on the LAN may act as a local Dynamic Host Configuration Protocol (DHCP) server and may receive requests for Domain Name System (DNS) server IP addresses from devices on the LAN. The DNS Proxy feature allows the router to send its own LAN address to devices that request DNS server IP addresses and to forward DNS queries to the real DNS servers after the WAN connection is established. The router can thus act as a proxy for devices on the LAN.

In forwarding DNS queries, the router caches the responses from the real DNS servers. Over time, the router's cache accumulates the DNS information most often requested, enabling the router to respond to most DNS queries coming from the LAN and reducing the packet overhead on the WAN interface.

In order for the DNS Proxy feature to work, the router must obtain the IP address of the real DNS server from the WAN when the WAN connection is established.

The ip dns server global configuration command enables DNS proxy server functionality on the router and causes the router to forward DNS queries to the actual DNS servers. The dns-server address global configuration command causes the router to respond to DNS queries with its own IP address.

FACILITY Debug Enhancement

Overview

This feature enables display of ASN.1-encoded ISDN FACILITY Information Element (IE) contents. All supported operations of the ISDN supplementary services—Advice of Charge (AOC), Two B-Channel Transfer (TBCT), Explicit Call Transfer (ECT), and Malicious Call Identification (MCID)—are now included as part of the debug messages. Prior to this enhancement, the debug isdn q931 command displayed the contents of the FACILITY IE in its raw hexadecimal format. Now, the parameters of FACILITY IE are displayed in text format along with parameter values where they are applicable and as they are relevant to the operation. In addition, the ASN.1-encoded Notification structure of the Notification-Indicator IE is also decoded. This debugging information is available for both incoming and outgoing FACILITY IEs in any message over an ISDN interface.

The debug isdn q931 command must be enabled to display the contents of the FACILITY IE. Following are examples of new messages displayed in the debug isdn q931 command output. See the debug isdn q931 command page for more details about the information displayed by the FACILITY IE.

Firewall ACL Bypass

For detailed information about this feature, see the following document:

http://www.cisco.com/en/US/docs/ios/12_3t/12_3t4/feature/guide/gt_aclby.html

Firewall Authentication Proxy for FTP and Telnet Sessions

The authentication proxy in the Cisco IOS firewall feature set currently supports only the HTTP protocol. Authentication proxy support has been extended to the FTP/Telnet protocols with this release. This release also introduces absolute timeout functionality to the authentication proxy feature. The absolute timeout sets a time window during which the authentication proxy on the enabled interface is active. As the absolute timer expires, the authentication proxy will be disabled. The addition of the absolute timeout upgrades the functionality of the authentication proxy and also meets the firewall requirements.

Firewall Intrusion Detection System (IDS) Enhancements

The Cisco IOS Intrusion Detection System (IDS) feature supports intrusion detection technology on all the Cisco IOS-based router platforms when the Cisco IOS firewall is present. The Cisco IOS IDS feature identifies 101 of the most common attacks, using signatures to detect patterns of misuse in network traffic. The Cisco IOS IDS acts as an in-line intrusion detection sensor, watching packets and sessions as they flow through the router, scanning each to match any of the IDS signatures. When the Cisco IOS IDS detects suspicious activity, it responds before network security can be compromised, and it logs the event through the Cisco IOS syslog or the Cisco Secure Intrusion Detection System (Cisco Secure IDS, formerly known as NetRanger) Post Office Protocol. The network administrator can configure the IDS system to choose the appropriate response to various threats.

Firewall N2H2 Support

N2H2 is globally deployed third-party URL filtering software that can filter HTTP requests, based on destination hostname, destination IP address, username, and password. It relies on a sophisticated URL database of more than 15 million sites organized into more than 40 categories using both Internet technology and human review. This feature enables the Cisco IOS firewall to do URL filtering based on the N2H2 server. When a Cisco 800 router receives an HTTP request, it sends a query request to the N2H2 server with the requested URL. The N2H2 server does some necessary lookups for the URL and sends back a query response. Based on the N2H2 server's response, the router either blocks the HTTP request by redirecting the browser to a block page or proceeds with normal HTTP processing.

For more information on this feature, see the following URL:

http://www.cisco.com/en/US/partner/docs/ios/12_2t/12_2t15/feature/guide/ft_n2h2.html

Firewall Support for SIP

This feature allows Session Initiation Protocol (SIP) signaling requests to traverse directly between gateways or through a series of proxies to the destination gateway or phone. After the initial request, if the Record-Route header field is not used, subsequent requests can traverse directly to the destination gateway address as specified in the Contact header field. Thus, the Cisco IOS firewall is aware of all surrounding proxies and gateways and allows the following functionality:

SIP signaling responses can travel the same path as SIP signaling requests.

Subsequent signaling requests can travel directly to the endpoint (destination gateway).

Media endpoints can exchange data.

For more information on this feature, see the following URL:

http://www.cisco.com/en/US/partner/docs/ios/12_2t/12_2t15/feature/guide/ft_fwsip.html

Firewall Support of SSL Encrypted HTTP Authentication Proxy Sign-On

The Firewall Support of SSL Encrypted HTTP Authentication Proxy Sign-On feature allows a user to encrypt the change of the username and password between the HTTP client and the Cisco IOS router via Secure Socket Layer (SSL) when authentication proxy is enabled on the Cisco IOS firewall, thereby ensuring confidentiality of the data passing between the HTTP client and the Cisco IOS router.

Firewall Websense URL Filtering

Websense is a third-party URL filtering software program that can filter HTTP requests, based on destination hostname, destination IP address, keywords, and username. Websense maintains a URL database of more than 20 million sites organized into more than 60 categories and subcategories. This feature enables the Cisco IOS firewall to do URL filtering based on the Websense server. When a Cisco 800 router receives an HTTP request, it sends a query request to the Websense server with the requested URL. The Websense server does some necessary lookups for the URL and sends back a query response. Based on the Websense server's response, the router either blocks the HTTP request by redirecting the browser to a block page or proceeds with normal HTTP processing.

For more information on this feature, see the following URL:

http://www.cisco.com/en/US/partner/docs/ios/12_2t/12_2t15/feature/guide/ftwebsen.html

Four-Wire Mode for SHDSL

The Four-Wire Mode for SHDSL feature adds four-wire support in fixed line-rate mode only on a single-port multiline G.SHDSL WIC or WIC-1SHDSL-V2. This feature builds on the existing features of the Multirate Symmetrical High-Speed Digital Subscriber Line (G.SHDSL) feature supported on the 1-port G.SHDSL WIC (WIC-1SHDSL). Four-Wire Mode for SHDSL supports the Cisco 2600XM series, Cisco 2691, Cisco 3600, and Cisco 3700 series routers and incorporates the latest firmware and the latest circuitry. The four-wire feature of G.991.2 doubles the bandwidth in ATM mode and increases usable distance over two pairs of wires.

This feature supports ATM in four-wire mode. Embedded Operation Channel (EOC) messages support for customer premise equipment (CPE) is provided for two-wire and four-wire modes.

Frame Relay—Multilink (MLFR-FRF.16)

The Multilink Frame Relay feature introduces functionality based on the Frame Relay Forum Multilink Frame Relay UNI/NNI Implementation Agreement (FRF.16). This feature provides a cost-effective way to increase bandwidth for particular applications by enabling multiple serial links to be aggregated into a single bundle of bandwidth. Multilink Frame Relay is supported on User-to-Network Interfaces (UNIs) and Network-to-Network Interfaces (NNIs) in Frame Relay networks.

Frame Relay Switched Virtual Circuits (SVC) over ISDN

The Frame Relay Switched Virtual Circuits over ISDN feature provides support for Frame Relay switched virtual circuits (SVCs) over ISDN BRI lines. Before the introduction of this feature, Frame Relay over ISDN supported Frame Relay permanent virtual circuits (PVCs) only. Frame Relay SVCs can be configured on dialer or BRI interfaces in the same way that SVCs are configured on serial interfaces.

For additional information on configuring Frame Relay and Frame Relay SVCs, see the "Configuring Frame Relay" chapter of the Cisco IOS Wide-Area Networking Configuration Guide at the following location:

Hookflash and DTMF Relay Transfer

Hookflash and DTMF Relay Transfer is a cost-effective way to transfer customer calls from first-level technical support to other agent groups for second-level support. The circuit between the transferrer and the transferee is released after the transferrer initiates the transfer and the remote switch connects the transferee and the transfer target.

Hot Standby Router Protocol (HSRP)

Hot Standby Router Protocol (HSRP) enables a set of routers to work together to present the appearance of a single virtual router or default gateway to the hosts on a LAN. HSRP is particularly useful in environments in which critical applications are running and fault-tolerant networks have been designed. By sharing an IP address and a MAC address, two or more routers that are acting as one virtual router are able to seamlessly assume the routing responsibility in the case of a defined event or an unexpected failure. This enables hosts on a LAN to continue forwarding IP packets to a consistent IP and MAC address so that the changeover of devices that are doing the routing is transparent to them and their sessions.

The routers in an HSRP configuration are known as an HSRP group or standby group. A single router selected from the group is responsible for forwarding the packets that hosts send to the virtual router. This router is known as the active router. Another router is selected as the standby router. If the active router fails, the standby router assumes the packet forwarding duties of the active router. Although an arbitrary number of routers may run HSRP, only the active router forwards the packets sent to the virtual router.

HSRP uses a priority scheme to determine which HSRP-configured router is to be the default active router. To configure a router as an active router, the router is assigned a priority that is higher than the priority of all the other HSRP-configured routers. The default priority is 100. If any of the routers is configured with a higher priority, those routers will be the active router.

HSRP works by the exchange of multicast messages that advertise priority among HSRP-configured routers. When the active router fails to send a hello message within a configured period of time, the standby router with highest priority becomes the active router. The transition of the packet-forwarding function between routers is completely transparent to all the hosts on the network.

HSRP-configured routers exchange three types of multicast messages.

Hello—The hello messages convey to other HSRP routers the router's HSRP priority and state information. By default, an HSRP router sends hello messages every 3 seconds.

Coup—When a standby router assumes the function of the active router, it sends a coup message.

Resign—A router that is the active router sends this message when it is about to shut down or when a router with a higher priority sends a hello message.

At any time, HSRP-configured routers will be in one of the following states:

Active—The router is performing packet-transfer functions.

Standby—The router is ready to assume packet-transfer functions if the active router fails.

Speaking and listening—The router is sending and receiving hello messages.

Listening—The router is receiving hello messages.

IP to ATM CoS Enhancements

The IP to ATM CoS feature implements a solution for coarse-grained mapping of quality of service (QoS) characteristics between IP and ATM, using Cisco Enhanced ATM port adapters (PA-A3) on Cisco 7200 and Cisco 7500 series routers. This category of coarse-grained QoS is often referred to as class of service (CoS). The resulting feature makes it possible to support differential services in network service provider environments.

With the Cisco IOS Release 12.3(4)T, the IP to ATM CoS feature has been enhanced to include support for the Cisco 7500 series router with either the PA-A3-8T1 IMA or PA-A3-8E1 IMA port adapters.

For more information about the IP to ATM CoS feature, see the "Quality of Service Solutions" section of the Cisco IOS Quality of Service Solutions Configuration Guide.

IPHC (cRTP/cUDP/cTCP)

Internet Protocol Header Compression (IPHC) includes compressed Routing Table Protocol (cRTP), compressed User Datagram Protocol (cUDP), and compressed Transport Control Protocol (cTCP) and allows low speed links to run more efficiently when IP headers are extremely large or of comparable size to the payload.

An IPHC-enabled interface sends only changes to the header instead of sending the entire header with every packet.

At the beginning of a transmission, the transmitting end (the compressor) sends a full header packet to the receiving end (the decompressor). After this initial packet, the compressor sends all other packets with headers that contain only the differences between them and the original full header. The decompressor maintains a copy of the original full header and reconstructs all the other packet headers by adding the changes to them.

IPsec NAT Transparency

The IPSec NAT Transparency feature introduces support for IP Security (IPSec) traffic to travel through the Network Address Translation (NAT) or Point Address Translation (PAT) point in the network by addressing many known incompatibilities between NAT and IPSec. This feature encapsulates IPSec packets in a User Datagram Protocol (UDP) wrapper, which allows the packets to travel across NAT devices.

A standard IPSec Virtual Private Network (VPN) tunnel would not work if there are one or more NAT or PAT points in the delivery path of the IPSec packet. This feature makes NAT IPSec aware, thereby allowing remote access users to build IPSec tunnels to home gateways.

http://www.cisco.com/en/US/docs/ios/12_3t/12_3t7/feature/guide/gtlmrip.html

LFI

Link Fragmentation Interleaving (LFI) allows a large packet to be divided into smaller fragments so that excessive head of line blocking can be avoided for smaller packets such as Voice over IP (VoIP) packets.

On slow speed interfaces (slower than T1), a packet with maximum transmission unit (MTU) can cause excessive head of line blocking in low latency priority queues (LLQs) especially in VoIP applications. The solution is to implement LFI on these interfaces.

The RPM-XF supports LFI on MLPPP interfaces and supports up to 200 LFI-enabled interfaces. LFI and PPP interfaces use the Multilink PPP (MLPPP) long sequence number fragment format headers.

LFI over multiple links in an MLPPP bundle is not supported. Receiving and reassembling out of sequence fragments is also not supported.

Mobile IP

Mobile IP is an open standard, defined by the Internet Engineering Task Force (IETF) RFC 2002, that allows users to keep the same IP address, stay connected, and maintain ongoing applications while roaming between IP networks. Mobile IP is scalable for the Internet because it is based on IP—any media that can support IP can support Mobile IP.

Cisco IOS software and its support for Mobile IP provide the technology that enables an IP node's ability to retain the same IP address and maintain existing communications while traveling from one network to another.

Mobile IP eliminates a stop-and-start approach to IP connectivity that is required with network location changes, thus enabling users to maintain the same IP address regardless of their point of attachment to the network.

Mobile IP has the following three components:

1. Mobile Node

The Mobile Node is a device such as a cell phone, PDA, or laptop whose software enables network roaming capabilities.

2. Home Agent

The Home Agent is a router on the home network that serves as the anchor point for communication with the Mobile Node; it tunnels packets from a device on the Internet, called a Correspondent Node, to the roaming Mobile Node. (A tunnel is established between the Home Agent and a reachable point for the Mobile Node in the foreign network.)

3. Foreign Agent

The Foreign Agent is a router that can function as the point of attachment for the Mobile Node when it roams to a foreign network, delivering packets from the Home Agent to the Mobile Node.

The care-of address is the termination point of the tunnel toward the Mobile Node when it is on a foreign network. The Home Agent maintains an association between the home IP address of the Mobile Node and its care-of address, which is the current location of the Mobile Node on the foreign or visited network.

The Mobile IP process has three main phases:

1. Agent Discovery—A Mobile Node discovers its Foreign Agent and Home Agent during agent discovery.

2. Registration—The Mobile Node registers its current location with the Foreign Agent and Home Agent during registration.

3. Tunneling—A reciprocal tunnel is set up by the Home Agent to the care-of address (current location of the Mobile Node on the foreign network) to route packets to the Mobile Node as it roams.

Mobile IP uses a strong authentication scheme for security purposes. All registration messages between a Mobile Node and a Home Agent are required to contain the Mobile-Home Authentication Extension (MHAE).

Mobile IP Home Agent Redundancy for Dynamic Mobile Networks

With the introduction of the Mobile IP Home Agent Redundancy for Dynamic Mobile Networks feature, the mobile router is capable of dynamically registering network(s) (or subnet) with its home agent. This functionality greatly simplifies deployment and provisioning.

To achieve this functionality, extra information is stored in the mobility binding. However, this extra information was not passed to the standby home agent in case of a redundant home agent configuration. Thus, the standby home agent would not know of a dynamically registered network and the stateful switchover was compromised. If the active home agent went down and the standby home agent took over, the dynamic network information was lost and the entire dynamic network would lose connectivity.

The Mobile IP Home Agent Redundancy for Dynamic Mobile Networks feature provides a solution to this problem by keeping the mobility bindings synchronized between the active and standby home agents. Now the standby home agent will have dynamic mobile network information stored in its mobility binding table ensuring a successful stateful switchover.

Dynamic network support for Cisco Mobile Networks was added in Cisco IOS Release 12.2(13)T. See "Cisco Mobile Networks" feature documentation for more information on this feature at the following location:

http://www.cisco.com/en/US/docs/ios/12_2t/12_2t4/feature/guide/ftmbrout.html

Mobile IP—Mobile Router DHCP Support for Dynamic CCoA and Foreign Agent Processing

The Mobile Router DHCP Support for Dynamic Collocated Care-of Address (DCCoA) and Foreign Agent (FA) Processing feature adds support for mobile router roaming on Ethernet interfaces that acquire an IP address dynamically via the Dynamic Host Configuration Protocol (DHCP). The interface can register using this acquired IP address as a DCCoA or register using a CoA acquired from a foreign agent. This behavior is true for all platforms that support Mobile IP beginning with Cisco IOS Release 12.3(14)T.

This feature adds support for FA processing of advertisements and registrations on DHCP roaming interfaces.

A Simple Network Management Protocol (SNMP) signaling capability is also added to support this feature on the Cisco 3200 Series Mobile Access Router with a Wireless Mobile Interface Card (WMIC). The WMIC uses SNMP trap messages to signal the mobile router that the Layer 2 wireless local-area network (WLAN) is either up or down.

Multicast Fast Switching Performance Improvement

The Multicast Fast Switching Performance Improvement feature provides improvement of up to 100 percent of the existing multicast path packet throughput. This feature targets software forwarding-based platforms for IPv4 multicast only.

Multicast VPN

Multicast Virtual Private Network (VPN) provides the ability to transport multicast traffic inside an MPLS-VPN using multicast tunneling. A single MPLS-VPN endpoint can send a multicast packet to all other destination endpoints in the MPLS-VPN.

A customer edge (CE) router sends a multicast packet customer packet (C-packet) to a provider edge (PE) router. The PE router creates a provider packet (P-packet) by adding either a GRE-IP header or an IP-IP header to this packet. The PE router then sends the P-packet to one or more provider routers (P routers) using multicast processing.

Multicast VPN supports only MPLS frame-based encapsulation.

Multicast VPN MIB

The Multicast VPN MIB feature was introduced in Cisco IOS Release 12.0(29)S. For detailed information about changes and enhancements to this feature in Cisco IOS Release 12.3(14)T, see the following document:

NAT—dCEF Support

The NAT—dCEF Support feature enhances the overall performance of Route Switch Processors on Cisco 7500 series routers by enabling line cards to perform address translation. Without this feature, any Distributed Cisco Express Forwarding (dCEF) switched packet that needs address translation must be switched by the RSC (Route Switch Controller), which increases load and reduces system performance and throughput. With the NAT—dCEF Support feature, Network Address Translation (NAT) is implemented on the line card level so that address translation is carried out at the switching path.

In distributed switching, the switching process occurs on versatile interface processor (VIP) and other interface cards that support switching. When dCEF is enabled, line cards, such as VIP line cards or Gigabit Switch Router line cards, maintain an identical copy of the forwarding information base (FIB) and adjacency tables. The line cards perform the express forwarding between port adapters, relieving the RSC of involvement in the switching operation. dCEF uses an interprocess communication (IPC) mechanism to ensure synchronization of FIBs and adjacency tables on the RSC and line cards. The NAT—dCEF Support feature also enables line cards to maintain a subset of the RSC NAT table. This enables the line cards to switch packets and perform express forwarding within and between port adapters. Because embedded address translation cannot occur at the line card level, packets that require payload translation are punted to the next higher-level switching mechanism in the RSC.

NAT—H.245 Tunneling Support

For detailed information about this feature, see the following document:

http://www.cisco.com/en/US/docs/ios/12_3t/12_3t11/feature/guide/nat245tl.html

Cisco 2851 Series Integrated Services routers

Cisco 3825 Series Integrated Services routers

Cisco 3845 Series Integrated Services routers

NAT-Performance & Scalability Enhancement-Timer Wheel

The NAT-Timer Wheel Enhancement feature reduces CPU utilization in cases where routers must manage large numbers of NAT Network Address Translation (NAT) entries, and eliminates the performance bottleneck caused by the previous timer tree model. By using a more efficient data structure and a priority queue to sort the timer and eliminate the sorting operation during a timer insertion, the NAT-Timer Wheel Enhancement Feature speeds the process of inserting and removing a timer, which improves the scalability of a router running NAT.

NAT-Performance Enhancement-CEF Switching Support

The NAT-CEF Switching Support feature enhances router performance by optimizing packet processing. Through Cisco Express Forwarding (CEF), decisions to translate, punt, drop, or forward a packet are made with a single lookup. To improve performance, packets that do not require translation and fragmented packets are not punted to the process level. Those packets that have special flags, such as TCP syn/fin/reset, are processed in the CEF path itself. Any action that is CPU-intensive is performed by a background process or by process-level NAT code.

NAT Routemaps Outside-to-Inside Support

For detailed information about this feature, see the following document:

http://www.cisco.com/en/US/docs/ios/12_3t/12_3t7/feature/guide/gtnrtsp.html

NAT—SIP Support

Session Initiation Protocol (SIP) is an application-layer signaling protocol for creating and controlling multimedia sessions with two or more participants and a client/server protocol transported over TCP or UDP. The messages in the protocol might have IP addresses embedded in the packet payload. If a message passes through a router configured with NAT, the embedded information is translated and encoded back to the packet.

No configurations changes are needed for this feature. However, the SIP proxy server or user agent may sometimes listen to SIP messages in the nonstandard ports. The following global configuration command is used to change the configuration:

ip nat service sip tcp port number

The number argument is the port number on which the SIP proxy server will listen for SIP messages.

NAT Support for H.323 Fragmented Control Messages

Control messages for most multimedia applications such as H.323 messages can arrive at a router as fragments. IP-level fragmentation is common and well understood, but some applications have control messages that can span across several IP datagrams, causing the control message of an application that uses TCP to arrive at a router running Network Address Translation (NAT) as multiple IP packets that are not fragmented.

Prior to the introduction of the NAT Support for H.323 Fragmented Control Messages feature, NAT required the entire control message to be present in a single IP packet. If NAT received a control message that was fragmented, the packet was dropped. This feature enables NAT to perform address translation against fragmented packets, and it provides support for H.323 packets that arrive in different TCP segments.

NAT—Support for H.323 v3 and v4 in v2 Compatibility Mode

H.323 is an ITU-T specification for transmitting audio, video, and data across a packet network. Four versions of the H.323 protocols are currently in use: v1, v2, v3, and v4. The NAT—Support for H.323 v3 and v4 in v2 Compatibility Mode feature enables Cisco Network Address Translation (NAT) routers to support messages coded in H.323 v3 and v4 when those messages contain fields compatible with H.323 v2. This feature does not add support for H.323 capabilities introduced in v3 and v4, such as new message types or new fields that require address translation.

NAT—Support of IP Phone to Cisco CallManager

Cisco IP phones use the Selsius Skinny Station Protocol to connect with and register to the Cisco CallManager. Messages flow back and forth that include IP address and port information used to identify other IP phone users with which a call can be placed.

To deploy Cisco IOS Network Address Translation (NAT) between the IP phone and the Cisco CallManager in a scalable environment, NAT needs to be able to detect the Selsius Skinny Station Protocol and understand the information passed within the messages.

When an IP phone attempts to connect to the Cisco CallManager and it matches the configured NAT translation rules, NAT will translate the original source IP address and replace it with one from the configured pool. This new address will be reflected in the Cisco CallManager and be visible to other IP phone users.

NAT listens on the default port of the Cisco CallManager to translate the Skinny messages. If the call manager uses a port other than the default port, that port needs to be configured, using the ip nat service skinny tcp port global configuration command. To disable the port, use the no form of this command. The syntax of this command is shown below:

ip nat service skinny tcp port number

no ip nat service skinny tcp port number

NextPort Voice Tuning and Background Noise Statistics with NextPort Dual-Filter G.168 Echo Cancellation

This feature allows you to dynamically configure voice services on the NextPort-based platforms: the Cisco AS5350, Cisco AS5400, Cisco AS5400HPX, and Cisco AS5850. This feature also provides improved voice quality and statistics reporting and adds dual-filter G.168 echo canceller capability in NextPort SPE firmware (SPEware) version 10.2.2 and later with Cisco IOS Release 12.3(11)T.

Dual-filter G.168 echo canceller capability has been added to the CSMV6 dial feature card (DFC) for NextPort platforms. The NextPort dual-filter G.168 echo canceller (EC) improves voice quality in VoIP connections by providing relatively less residual echo leakage, better non-linear processing (NLP) timing, less clipping, and better comfort noise generation (CNG) in most environments.

The dual-filter G.168 echo canceller features two concurrently operating adaptive filters (which control echo tail coverage) and two double-talk detection functions. In addition, the comfort noise model uses "Hoth noise" spectrum shaping to better replicate the true noise spectrum.

The NextPort dual-filter G.168 echo canceller uses the same voice-tuning (VCtune) interface for configuring voicecap parameters as the Cisco-proprietary G.164 echo canceller. Adjusting the dual-filter echo canceller is carried out by using a voicecap or by using the Cisco IOS command-line interface (CLI) during configuration.

OSPF MIB Support of RFC 1850 and Latest Extensions

This release updates the OSPF MIB support to the latest RFC 1850 and adds the latest draft extensions. For more information regarding the definitions of the draft extensions, see the CISCO-OSPF-MIB.my and CISCO-OSPF-TRAP-MIB.my files that are available through the Cisco MIB FTP site at the following URL:

ftp://ftp.cisco.com/pub/mibs/v2/

For routers that are running Cisco IOS Release 12.0(26)S and later releases, the OSPF MIB and CISCO OSPF MIB will be supported only for the first OSPF process (except for MIB objects that are related to virtual links and sham links). SNMP Traps will be generated for OSPF events that are related to any of the OSPF processes. There is no workaround for this situation.


Note The CISCO-OSPF-MIB.my is a read-only MIB.

Outbound Control Packet Decoding Implemented for VPDN Debug Output Using the L2TP Protocol

Before Cisco IOS Release 12.3(14)T, only incoming Layer 2 Transport Protocol (L2TP control packets were decoded and displayed in the output of virtual private dialup network (VPDN) debug command data with the debug vpdn l2x-packets EXEC command enabled. To create L2TP tunnels and sessions, the software sends control packets to the peer. If you had wanted to troubleshoot the sessions effectively during the control-channel establishment phase of those sessions, it was necessary to review debug data from both outgoing and incoming control packets, on both the LAC and LNS. Also, for outgoing L2TP control packets, the hexadecimal packet dump was displayed on the screen only, which made it difficult to troubleshoot interoperability issues that required packet analyzers, or to use data from peer or vendor devices to analyze the outgoing L2TP control packets.

To be consistent with other protocol-level debug output in the Cisco IOS software, L2TP control packet debug command output needed to show bidirectional protocol packet decode data, rather than just the incoming only data that had been displayed.

Cisco IOS Release 12.3(14)T implements the decoding of outgoing L2TP hexadecimal control messages, which includes the L2TP headers and the attribute-value pairs that are transacted in each outgoing control message. VPDN debug data can also be directed into a file so that packet analyzers can be used on the data.

To use this feature, you must enable the debug vpdn l2x-packets command on the router in which the decoded outgoing control packets debug data needs to be shown.


Note The debug vpdn l2x-packets command can result in a large number of debug messages and should be used only on a debug chassis with a single active session.


Following is sample decoded debug output, followed by a list of the attribute-value pairs that are supported in the enhanced debug command output:

Out-of-Band to In-Band DTMF Relay for Cisco IOS Voice Gateways

This feature provides RFC 2833 capability, enabling DTMF relay communication between SIP devices and non-SIP endpoints using Cisco CallManager 4.0.

For detailed information about this feature, see the Configuring Enhanced Conferencing and Transcoding for Voice Gateway Routers chapter in the Cisco CallManager and Cisco IOS Interoperability Guide:

http://www.cisco.com/en/US/docs/ios/voice/cminterop/configuration/guide/vc_enh_confr_vgr.html

Overlap Signaling Processing on H.323 Terminating Gateways

In an overlap signaling scenario, the called number in the SETUP message does not contain enough digits to match the incoming dial peer for the dial peer to select the right application. With this change, the H.323 layer determines if a partial match is detected and appends the called number with the needed digits. The new called number is checked to see if it matches any of the incoming dial peers. If either full match or no match is returned, the call will proceed with a SETUP procedure.

For detailed information about this feature, see the Configuring MGCP PRI Backhaul and T1 CAS Support for Cisco CallManager chapter in the Cisco CallManager and Cisco IOS Interoperability Guide:

http://www.cisco.com/en/US/docs/ios/voice/cminterop/configuration/guide/vc_mgcp_t1cas.html

Quality of Service for Virtual Private Networks

This feature allows the customer to configure Quality of Service (QoS) features and tunneling/crypto on the same interface.

As VPNs grow to include data, voice, and video traffic, the different types of traffic need to be handled differently in the network. QoS and bandwidth management features allow a VPN to deliver high transmission quality for time-sensitive applications such as voice and video. Each packet is tagged to identify the priority and time sensitivity of its payload, and traffic is sorted and routed based on its delivery priority. Cisco VPN solutions support a wide range of QoS features.

For more details on this feature, see the following URL:

http://www.cisco.com/en/US/tech/tk543/tk757/technologies_tech_note09186a00800b3d15.shtml

Query Mode Definition Per Trustpoint

Certificates and certificate revocation lists (CRLs) are used by your router when a CA is used. Normally certain certificates and all CRLs are stored locally in the router's NVRAM, and each certificate and CRL uses a moderate amount of memory. The Query Mode Definition Per Trustpoint allow you to define a query for a specific trustpoint or for the trustpoints defined on a particular router.

For detailed information about this feature, see the following document:

http://www.cisco.com/en/US/docs/ios/12_3t/12_3t7/feature/guide/gt_qerym.html

Quick Autoenroll

The Autoenroll feature enables a router to automatically trigger an enrollment when the elapsed lifetime of an existing certificate has reached a certain percentage (for example, after 70 percent of the lifetime has passed, the router automatically enrolls for a new certificate). When no certificate exists, a 1-minute timer is set to trigger autoenrollment as soon as the clock has been set manually or by using Network Time Protocol (NTP).

The Quick Autoenroll feature shortens the 1-minute time when no certificate exists. Instead of having to wait 1 minute, an enrollment will occur after 15 seconds. This feature applies to manually configured autoenroll using the current auto-enroll command. No new or additional commands or keywords are necessary for this feature to work. This feature also applies when the configuration sent to the device includes autoenroll (that is, to any subsystem that calls for the "parse_configure() with RES_MANUAL" flag to enter the auto-enroll command, for example, during a Trusted Transitive Introduction [TTI] exchange).

When the configuration is read from NVRAM or copied from file systems, autoenroll will still have a 1-minute timer. The 1-minute timer prevents the read-in of multiple trustpoints from configuration and trigger enrollments that occur simultaneously.

Secure SNMP Views

The USM, VACM and Community MIBs have information that can potentially be used to gain access to the router using SNMP. Therefore, the USM, VACM, and Community MIBs are excluded from the default SNMP access view so as not to allow remote access unless specifically configured. However, when an SNMP view is created with any parent object identifier (OID) of these MIBs included (for example "internet included"), these MIBs also get included in the view. To increase security, the Secure SNMP Views enhancement excludes these MIBs from SNMP access views even when parent OIDs are included in the view. Prior to this release, when configuring SNMP views with parent OIDs that include the USM, VACM, or Community OIDs, the user was required to explicitly exclude them. For example, the following configuration can be used for excluding security-sensitive MIBs from the SNMP view named "test":

! - include all MIBs under the parent tree "internet" snmp-server view test internet included

! -- exclude snmpUsmMIB snmp-server view test 1.3.6.1.6.3.15 excluded

! -- exclude snmpVacmMIB snmp-server view test 1.3.6.1.6.3.16 excluded

! -- exclude snmpCommunityMIB snmp-server view test 1.3.6.1.6.3.18 excluded

Beginning in Cisco IOS Releases 12.0(26)S and 12.2(2)T, the USM, VACM, and Community MIBs are excluded from any parent OIDs in a configured view by default. If you wish to include these MIBs in a view, you must now explicitly include them.

Service Assurance Agent (SAA)—MPLS VPN Path Jitter

The Service Assurance Agent (SAA)—MPLS VPN Path Jitter feature supports the use of the ICMP Path Jitter probe operation in an MPLS/VPN environment. ICMP Path Echo operations record statistics for each hop along the path that the operation takes to reach it destination. The ICMP Path Echo operation computes this hop-by-hop response time between a Cisco router and any IP device on the network by discovering the path using traceroute. ICMP Path Jitter uses multiple ICMP packets to determine jitter and packet loss on a hop-by-hop basis.

This feature allows you to specify a Virtual Private Network (VPN) forwarding table for a Path Echo operation using the vrfName command in SAA PathJitter configuration mode. The ICMP Path Jitter operation records statistics for each hop along the path to the destination.

Service Selection Gateway (SSG)

Service Selection Gateway (SSG) is a switching solution for service providers who offer intranet, extranet, and Internet connections to subscribers using broadband access technology such as digital subscriber lines (DSL), cable modems, or wireless to allow simultaneous access to network services. The Service Selection Gateway MIB enables network administrators to use Simple Network Management Protocol (SNMP) to monitor and manage SSG. The SSG MIB contains objects that correspond to and allow the monitoring of several important SSG features, including SSG AutoDomain, SSG Port-Bundle Host Key, and SSG TCP Redirect for Services. For detailed definitions of MIB objects, see the CISCO-SSG-MIB.

Service Selection Gateway (SSG) Features in Release 12.3(4)T

For detailed information about this feature, see the following document:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123newft/123t/123t_4/ssg/index.htm

Session Initiation Protocol (SIP)

Session Initiation Protocol (SIP) is an ASCII-based, application-layer control protocol (defined in RFC 2543) that can be used to establish, maintain, and terminate calls between endpoints.

Like other VoIP protocols, SIP is designed to address the functions of signaling and session management within a packet telephony network. Signaling allows call information to be carried across network boundaries. Session management provides the ability to control the attributes of an end-to-end call.

This feature is supported on the Cisco 827-4V router beginning with this release. The SIP feature on Cisco 827-4V router supports only basic calls between two end points. Supplementary services like call waiting, call forwarding, etc. are not supported on the Cisco 827-4V router.

SNA Switching Services Enterprise Extender for IP Version 6

SNA Switching Services (SNASw) announces hostname configuration support for Enterprise Extender (EE) connections. This allows SNASw EE links over an IP Version 6 backbone, and also enables Global Connection Network (also known as GVRN - Global Virtual Routing Node) to work when Network Address Translation (NAT) is in place between the connecting networks (IP Version 4 or IP Version 6). This feature adds an IPv6 keyword to the snasw link and snasw port commands.

For detailed information on configuring IPv6, see the following document:

The SNMP v1/v2c PDU Conversions for Proxy Forwarder feature brings all images and platforms that include the SNMP Proxy subsystem (sub_snmp_proxy.o) into partial compliance with RFC 2576. RFC 2576 defines coexistence between three versions of the Internet-standard Network Management Framework: SNMPv3, SNMPv2, and SNMPv1. The only exception to full compliance with RFC 2576 is that this release of Cisco IOS software does not yet support version translations for Simple Network Management Protocol (SNMP) notifications.

http://www.cisco.com/en/US/docs/ios/12_3t/12_3t2/feature/guide/gtssmma.html

SSG 3-Key Authentication

The SSG 3-Key Authentication feature enables Service Selection Gateway (SSG) to authenticate Cisco Subscriber Edge Services Manager (SESM) users on the basis of three keys: username, password, and mobile station integrated services digital network (MSISDN) number. Before the introduction of this feature, users logging into SESM were authenticated on the basis of username and password only (2-key authentication).

When SSG 3-key authentication is used, users are required to provide their MSISDN number (which is typically their phone number), in addition to username and password, at SESM login. RADIUS attribute 31 (calling-station ID) is used to communicate the MSISDN number in account logon requests sent from SESM to SSG and in access requests sent from SSG to a AAA server. When 3-key authentication is used, all host and connection accounting packets for the user contain the MSISDN number. SSG 3-key authentication is performed for account logon only, not for service logon; however, SSG will include the MSISDN number in the access requests for service logons.

SSG AAA Transaction Enhancements

The Service Selection Gateway (SSG) AAA transactions for host logon and service profile downloading have been enhanced. The AAA server can now handle multiple SSG host logon and service profile download requests concurrently without stopping SSG processes.

SSG Aware On-Demand IP Address Renewal

For detailed information about this feature, see the following document:

http://www.cisco.com/en/US/docs/ios/12_3t/12_3t14/feature/guide/sgb_odip.html

SSG Complete ID

The SSG Complete ID feature provides enhancements to the interaction between Service Selection Gateway (SSG) and Cisco Subscriber Edge Services Manager (SESM) by allowing SSG to pass along the following information where available:

Client IP address

Client MAC address

Subinterface

Virtual path identifier/virtual channel identifier (VPI/VCI)

Mobile station integrated services digital network (MSISDN) number

This feature provides a more flexible way of identifying a client, which can be a single user on a PC, a site managing many users, or a transit user at a wireless (WLAN) hot spot location. The SSG Complete ID feature also enables SESM to offer greater customization of Web portals, specifically by location; so, for example, each WLAN hot spot can have its own branded portal.

SSG MIB Extensions

The Service Selection Gateway MIB enables network administrators to use Simple Network Management Protocol (SNMP) to monitor and manage SSG. The SSG MIB contains objects that correspond to various SSG features and that allow the collection of statistics and management of certain SSG configurations.

In Cisco IOS Release 12.3(8)T, the SSG MIB has been enhanced to provide statistics and the ability to manage the configuration of the SSG Transparent Autologon feature. The SSG Transparent Autologon feature enables SSG to authenticate and authorize users based on IP packets received from users. SSG authorizes users based on the source IP address received on the downlink interface. The SSG MIB includes objects for reporting transparent autologon statistics such as the current number of transparent passthrough, suspect, waiting-for-authorization, and unidentified users. The MIB also includes read-write objects that allow certain SSG transparent autologon thresholds and values to be configured in the MIB in addition to configuration using the command-line interface.

For detailed definitions of the SSG MIB objects, see the CISCO-SSG-MIB. To locate and download MIBs, use Cisco MIB Locator found at the following URL:

http://www.cisco.com/go/mibs

SSG Open Garden Configuration Enhancements

A Service Selection Gateway open garden is a collection of websites or networks that subscribers can access as long as they have physical access to the network. Subscribers do not have to provide authentication information before accessing the websites in an open garden. Before the introduction of this feature, open garden services had to be configured in local service profiles. The SSG Open Garden Enhancements allows service profiles for open garden services to be defined and managed locally or remotely on the RADIUS server.

SSG Permanent TCP Redirection

For detailed information about this feature, see the following document:

SSG Support for Overlapping Subscriber IP Addresses

For detailed information about this feature, see the following document:

http://www.cisco.com/en/US/docs/ios/12_3t/12_3t11/feature/guide/gtssgovr.html

SSG Support for RADIUS Attributes 27 and 29

The SSG Support for Radius Attributes 27 and 29 feature introduces SSG compliance with RFC 3580 with respect to RADIUS attributes 27 (Session-Timeout) and 29 (Termination-Action). RFC 3580 recommends using attributes 27 and 29 in Access-Accept packets during authentication to enforce periodic reauthentication of users. For details, see RFC 3580, "IEEE 802.1X Remote Authentication Dial In User Service (RADIUS) Usage Guidelines."

For instances that indicate reauthentication after the session timeout, SSG uses the cached username and password while performing reauthentication. If SSG does not have these credentials, the session is brought down as if reauthentication had failed. If a particular deployment makes use of one-time passwords for authenticating users, SSG reauthentication will fail and the session will be brought down.

For SSG transparent autologon (TAL) hosts (TAL users who have host objects created on SSG), SSG will perform TAL reauthorization upon session timeout whenever attribute 29 is present in the RADIUS profile of the user. (Note that for TAL users, SSG performs reauthorization, not reauthentication, because the user profile is downloaded on the basis of the IP address and service password.)

In SSG RADIUS proxy deployments, SSG will not perform session timeout processing when attribute 29 is present in the Access-Accept packet and is set to reauthenticate.

SSG Support for Subnet Based Authentication

The Subnet-Based Authentication for SSG feature allows a service provider to identify subscribers to services by their subnet, rather than by a subscriber's IP address.

http://www.cisco.com/en/US/docs/voice_ip_comm/cusrst/admin/srst/configuration/guide/srs_over.html

RFC 2833 DTMF Support from SCCP Devices to Cisco Unity Express

Cisco Skinny Client Control Protocol (SCCP) phones, such as those used with Cisco SRST systems, provide only out-of-band DTMF digit indications. To enable SCCP phones to send digit information to remote SIP-based IVR and voice-mail applications, Cisco SRST 3.2 and later versions provide conversion from the out-of-band SCCP digit indication to the SIP standard for DTMF relay, which is RFC 2833. You select this method in the SIP VoIP dial peer using the dtmf-relay rtp-nte command.

For detailed information about this feature, see the "Preparing Cisco SRST Support for SIP" chapter in the Cisco IOS Survivable Remote Site Telephony Version 3.2 System Administrator Guide:

http://www.cisco.com/en/US/docs/voice_ip_comm/cusrst/admin/srst/configuration/guide/srstsa.html

Translation Profiles Support (CME and SRST)

Cisco SRST 3.2 supports translation profiles. Translation profiles allow you to group translation rules and to associate translation rules with the following:

Called numbers

Calling numbers

Redirected called numbers

For detailed information about this feature, see the "Setting Up Call Handling" chapter in the Cisco IOS Survivable Remote Site Telephony Version 3.2 System Administrator Guide:

Survivable Remote Site Telephony (SRST) 3.3

Secure Cisco IP phones that are located at remote sites and that are attached to gateway routers can communicate securely using the WAN with Cisco CallManager. But if the WAN link or Cisco CallManager goes down, all communication through the remote phones becomes nonsecure. To overcome this situation, gateway routers can now function in secure SRST mode, which activates when the WAN link or Cisco CallManager goes down. When the WAN link or Cisco CallManager is restored, Cisco CallManager resumes secure call-handling capabilities.

Secure SRST provides new SRST security features such as authentication, integrity, and media encryption. Authentication provides assurance to one party that another party is whom it claims to be. Integrity provides assurance that the given data has not been altered between the entities. Encryption implies confidentiality; that is, that no one can read the data except the intended recipient. These security features allow privacy for SRST voice calls and protect against voice security violations and identity theft.

For detailed information about this feature, see the following document:

http://www.cisco.com/univercd/cc/td/doc/product/voice/srst/srst33/srst33ad/index.htm

See the Trunk-Management Features document for configuring information.

For detailed information about this feature, see theVoIP Alternate Path Fallback SNMP Trap document:

http://www.cisco.com/en/US/docs/ios/12_3t/12_3t14/feature/guide/pstntrap.html

VPDN MIB Enhancements for per-VRF Session Counting

An extension has been added to the virtual private dialup network (VPDN) CISCO-VPDN-MGMT-MIB that returns the total number of active sessions for each VPDN template. For customers that associate a VPDN template to each VPN routing and forwarding (VRF) instance, this MIB extension provides a way to monitor session usage per VRF.

Service providers can terminate sessions from multiple customer accounts on the same L2TP network server (LNS). The sharing of the LNS is done by creating one VRF per customer. Session limits on VPDN templates and VPDN groups are configured to control the allocation of sessions among customers and among users within the same customer account. A VPDN template is associated with each VRF, and its session limit restricts the total number of sessions for a customer account. Within that account, users may be assigned to different VPDN groups as their access requirements dictate. Session limits on VPDN groups further control the allocation of customer sessions among its users. In such a setup, the service provider must use the Simple Network Management Protocol (SNMP) to retrieve the total number of active sessions per customer to monitor their usage on the LNS.

Prior to the introduction of this MIB enhancement, only the total number of sessions on the LNS across all customer accounts could be retrieved through SNMP. This enhancement extends the CISCO-VPDN-MGMT-MIB to include a read-only table of VPDN template entries, with each entry reporting the number of active sessions across all VPDN groups that are associated with that template. The table entries can be accessed individually using GET requests or consecutively using repeated GET-NEXT requests.

Limitations and Restrictions

The following sections contain limitations and restrictions that apply to Cisco IOS Release 12.4.

Cisco IOS IP SLAs Proactive Threshold Monitoring Limitation

It has been observed that when trying to configure proactive threshold monitoring for a Cisco IOS IP Service Level Agreements (SLAs) Internet Control Message Protocol (ICMP) echo operation, the rtr reaction-configuration operation-number threshold-type consecutive consecutive-occurrences command does not work. We recommend that you use the ip sla monitor operation-number command to reconfigure the ICMP echo operation and use the ip sla monitor reaction-configuration operation-number threshold-type consecutive consecutive-occurrences command to reconfigure proactive threshold monitoring.

SNMP Version 1 BGP4-MIB Limitations

You may notice incorrect BGP trap OID output when using the SNMP version 1 BGP4-MIB that is available for download at ftp://ftp.cisco.com/pub/mibs/v1/BGP4-MIB-V1SMI.my. When a router sends out BGP traps (notifications) about state changes on an SNMP version 1 monitored BGP peer, the enterprise OID is incorrectly displayed as .1.3.6.1.2.1.15 (bgp) instead of .1.3.6.1.2.1.15.7 (bgpTraps). The problem is not due to any error with Cisco IOS software. This problem occurs because the BGP4-MIB does not follow RFC 1908 rules regarding version 1 and version 2 trap compliance. This MIB is controlled by IANA under the guidance of the IETF, and work is currently in progress by the IETF to replace this MIB with a new version that represents the current state of the BGP protocol. In the meantime, we recommend that you use the SNMP version 2 BGP4-MIB or the CISCO-BGP4-MIB to avoid an incorrect trap OID.
