Application Performance Assurance Network Module

Cisco Application Performance Assurance (NME-APA) lets you manage traffic by enabling or disabling the flow of packets through the router and the service module. There are two interfaces to configure for traffic management; the router interface and the service module interface.

Use the service-module apa traffic-management [monitor | inline] to configure the traffic management mode on the router interface.

Monitor mode will copy the packet and designate the copy as the one forwarded to NME-APA.

Inline mode will send the packet to NME-APA, rather than send a copy of the packet to NME-APA. Once NME-APA has finished processing the packet, it will send it back to the router.

Use the Application Performance Assurance (APA) graphical user interface (GUI) to configure the service module interface.

http://www.cisco.com/en/US/docs/ios/voice/sip/configuration/guide/sip_cg-msg_tmr_rspns.html

SIP Multicast Music on Hold (MoH)

The Session Initiation Protocol (SIP) Multicast Music on Hold (MoH) feature allows the SIP gateway to subscribe to multicast music on hold when the SIP gateway is put on hold by the Cisco Unified Communications Manager.

When a VoIP phone puts a call on hold, the Cisco Unified Communications Manager asks the MoH server to stream Real-Time Transport Protocol (RTP) packets on a preconfigured multicast address. The Cisco Unified Communications Manager also sends a midcall invite with the "recv-only" attribute and multicast address to the SIP gateway. The SIP gateway subscribes to this multicast address. RTP packets are received from the MoH server and relayed by the SIP gateway to the voice interfaces.

When the VoIP phone resumes the call, the SIP-Service Provider Interface (SPI) instructs the multicast MoH server to unsubscribe from the multicast group. The IP layer drops any received multicast packets. The two-way audio channel is reestablished between the plain old telephone system (POTS) phone and the VoIP phone.

For more information on the Music on Hold features in Cisco Unified Communications Manager, see the following:

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/admin/7_0_1/ccmcfg/b04mohas.html

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/admin/7_0_1/ccmcfg/b04mohfx.html

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/admin/7_0_1/ccmcfg/b04mohsv.html

http://www.cisco.com/en/US/docs/ios/voice/cminterop/configuration/guide/vc_ucm_mgcp_gw.html#wp1063184

The following commands are associated with the SIP Multicast Music on Hold feature:

ccm-manager music-on-hold

cm-manager music-on-hold bind

debug ccm-manager music-on-hold

show ccm-manager music-on-hold

The ccm-manager music-on-hold command enables the multicast MoH feature. The feature is turned off by default. The ccm-manager music-on-hold bind command binds the multicast music-on-hold feature to a designated interface, which decreases bandwidth usage. The debug ccm-manager music-on-hold command enables debugging. The show ccm-manager music-on-hold command displays media information.

For detailed information about the commands associated with the SIP Multicast Music on Hold feature, see the Cisco IOS Voice Command Reference:

http://www.cisco.com/en/US/docs/ios/voice/command/reference/vr_book.html


Note SIP Multicast Music on Hold (MoH) is not supported on Cisco AS5400XM or Cisco AS5350XM (or any Cisco AS5xxx) platform.


SIP SRTP Fallback to Nonsecure RTP for CUBE

The SIP SRTP Fallback to Nonsecure RTP feature enables a Cisco IOS SIP gateway to fall back from SRTP to RTP by accepting or sending an RTP/AVP(RTP) profile in response to an RTP/SAVP(SRTP) profile. This feature also allows inbound and outbound SRTP calls with nonsecure SIP signaling schemes (such as SIP URL) and provides the administrator the flexibility to configure TLS, IPsec, or any other security mechanism used in the lower layers for secure signaling of crypto attributes. This functionality was extended to the Cisco Unified Border Element (CUBE) in Cisco IOS Release 12.4(22)T.

For more information about configuring SRTP fallback and negotiation, see the srtp, srtp negotiate, and voice-class sip srtp negotiate commands in the Cisco IOS Voice Command Reference at http://www.cisco.com/en/US/docs/ios/voice/command/reference/vr_book.html.

SIT Detection and Reporting

The SIT Detection and Reporting feature provides detection of the eight U.S. special information tones (SITs) and reporting of the detected SIT with a preassigned disconnect cause code for disconnect supervision. This capability is supported for analog FXO trunk and T1/E1 channel-associated signaling (CAS) FXO loop-start. The SIT reporting complies with standard Q.850 messages in order for fax servers to uniquely identify each condition.

The SIT detection and reporting feature enabled by the supervisory sit us command is supported only on C5510 digital signal processors (DSPs). No other DSPs support this feature.

For more information, see the supervisory sit us command in the Cisco IOS Voice Command Reference:

http://www.cisco.com/en/US/docs/ios/voice/command/reference/vr_s12.html#wp1201855

For detailed information about this feature, see the following:

http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/admin/configuration/guide/cmelocal.html

VRF Support on Cisco Unified Communications Manager Express, Survivable Remote Site Telephony and Secure VRF Traversal for Audio Calls

The Virtual Route Forwarding (VRF) feature divides a physical router into multiple logical routers, each having its own set of interfaces and routing and forwarding tables. Adding VRF awareness to voice gateways allows a voice gateway to exist in the same router as a customer edge (CE) or provider edge (PE) WAN router.

http://www.cisco.com/en/US/docs/ios/qos/configuration/guide/qos_frhqf_support.html

FXO Delayed Caller ID Delivery

Before Cisco IOS Release 12.4(11)XW, Foreign Exchange Office (FXO) Caller ID in North America was delivered between the first and second ring cycles based on the Telcordia GR-30-CORE standard. FXO software was configured to wait for Caller ID delivery before initiating the call setup for the next leg. As a result, the destination endpoint did not start ringing until after 1.5 to 2 ring cycles on the FXO port.

Beginning with Cisco IOS Release 12.4(11)XW, the immediate keyword is added to the connection plar opx command. When this keyword is included in the syntax, the FXO port sets up calls immediately so that the ring-cycle discrepancy is eliminated, and the perception of the number of rings is the same for both the caller and the called party. When the Caller ID is available, it is forwarded to the called number. If the called party answers the call before the Caller ID has been forwarded, the Caller ID update will not be forwarded to the display at the called party. Refer to the Cisco IOS Voice Command Reference:

http://www.cisco.com/en/US/docs/ios/voice/command/reference/vr_book.html

G.729br8 Codec as a Superset of G.729r8 and G.729br8 Codecs

The G.729br8 Codec as a Superset of G.729r8 and G.729br8 Codecs feature enables a Cisco IOS Session Initiation Protocol (SIP) gateway to treat G.729br8 as a superset of G.729r8 (G.729 or G.729a) and G.729br8 (G.729b or G.729ab). When this feature is enabled, the Cisco IOS gateway presumes that the remote endpoint supports both G.729r8 and G.729br8 codecs and negotiates which codec to use based on the local configuration. Similarly, when the Cisco IOS SIP gateway sends a G.729br8 offer, it can accept either a G.729r8 or G.729br8 response from the remote endpoint. In both cases, the negotiated codec is downloaded to the DSP and used by both endpoints.

For more information about this feature, see the g729-annexb-all and voice-class sip g729 annexb-all commands in the Cisco IOS Voice Command Reference at http://www.cisco.com/en/US/docs/ios/voice/command/reference/vr_book.html.

Cisco IOS IP Service Level Agreements (SLAs) is a capability embedded in Cisco IOS software that allows Cisco customers to understand IP service levels, increase productivity, lower operational costs, and reduce the frequency of network outages. In Cisco IOS Release 12.4(7), support for the IP SLAs Responder in IP Base Cisco IOS Packaging was introduced on several Cisco platforms. The IP SLAs Responder provides the capability to easily obtain precision network response time measurements between Cisco IOS source and destination devices. In the IP Base feature set, the IP SLAs Responder supports the User Datagram Protocol (UDP) echo, UDP jitter, and TCP connect operations.

In Cisco IOS 12.4(20)T, support for the IP SLAs Responder in IP Base Cisco IOS Packaging is made available on a larger number of Cisco platforms. Use Cisco Feature Navigator to find information about platform support and Cisco IOS and Catalyst OS software image support. To access Cisco Feature Navigator, go to http://www.cisco.com/go/cfn. An account on Cisco.com is not required.

IP SLAs VRF Aware 2.0

The IP SLAs VRF Aware 2.0 feature provides the capability to monitor IP service levels within Multiprotocol Label Switching (MPLS) Virtual Private Networks (VPNs). Using IP SLAs within MPLS VPNs allows service providers to plan, provision, and manage IP VPN services according to the service level agreement (SLA) for a customer. Use the vrf command to configure an IP SLAs operation for a specific VPN by entering a VPN routing and forwarding (VRF) name.

In Cisco IOS Release 12.2(2)T, support for VRF awareness was introduced for the following IP SLA operations:

ICMP echo

Path echo

Path jitter

UDP echo

UDP jitter

In Cisco IOS Release 12.4(20)T, support for VRF awareness is made available for the following additional IP SLA operations:

DNS

PKI—CLI to Control Certificate Revocation List (CRL) Cache

The PKI—CLI to Control Certificate Revocation List (CRL) Cache feature allows the administrator to control the CRL cache size. CRLs are received by Cisco IOS software in Distinguished Encoding Rules (DER) encoded format. Because processing a DER encoded CRL uses CPU time, Cisco IOS software allows CRLs either to be stored in cache after being processed or to be decoded for the first time. Configuring the CRL cache size allows the amount of memory used for the CRL cache to be reduced (for instance, if low memory conditions exist) or to be increased for better performance (for instance, when a large number of CRLs are being processed).

The following commands were introduced or modified by this feature: crypto pki crl cache and show crypto pki crls. The crypto pki crl cache command allows the administrator to set the maximum amount of volatile memory used to cache CRLs. When the crypto pki crl cache command is configured, the show crypto pki crls command output includes information on the CRL cache size.

For detailed information about the commands that are introduced or modified by the PKI—CLI to Control Certificate Revocation List (CRL) Cache feature, see the Cisco IOS Security Command Reference:

SIP SRTP Fallback to Nonsecure RTP

The SIP SRTP Fallback to Nonsecure RTP feature enables a Cisco IOS SIP gateway to fall back from SRTP to RTP by accepting or sending an RTP/AVP(RTP) profile in response to an RTP/SAVP(SRTP) profile. This feature also allows inbound and outbound SRTP calls with nonsecure SIP signaling schemes (such as SIP URL) and provides the administrator the flexibility to configure TLS, IPsec, or any other security mechanism used in the lower layers for secure signaling of crypto attributes.

For more information about configuring SRTP fallback and negotiation, see the srtp, srtp negotiate, and voice-class sip srtp negotiate commands in the Cisco IOS Voice Command Reference at http://www.cisco.com/en/US/docs/ios/voice/command/reference/vr_book.html.

http://www.cisco.com/en/US/docs/ios/12_3/sip/configuration/guide/ip_local.html

ISDN Setup: Hash Character Within Called Party Information Element

Before Cisco IOS Release 12.4(15)T, for overlap receiving, the "sending complete" indication was obtained through the Sending Complete IE. A hash mark (#) character received in the Called Party Number IE of an Information message was notified to the application without any special consideration and simply passed "as is" for number matching.

Starting with Cisco IOS Release 12.4(15)T, the hash mark (#) within the Called Party Number IE can also be used as an indication of "sending complete" and digit collection is stopped. As a result, the hash mark is treated as a terminating character for the Called Number. Receiving this hash mark character is equivalent to receiving a Sending Complete IE.

This feature is enabled by using the following command:

isdn overlap-receiving terminating-char #

L2TP Congestion Avoidance

Warm Reload

The Warm Reload feature is supported on the Cisco 7200 VXR router with the NPE-G2 network processing engine. The Warm Reload feature allows users to reload their routers without reading images from storage. That is, the Cisco IOS image reboots without ROM monitor mode (ROMMON) intervention by restoring the read-write data from a previously saved copy in the RAM and by starting execution without either copying the image from flash to RAM or self-decompression of the image. Thus, the overall availability of the system improves because the time to reboot the router is significantly reduced.

X.25 Call Record

The X.25 Call Record feature makes it possible to generate a record on the source, destination, and intermediate routers for each X.25 call made through those routers. The Record also logs that Call Record onto a specified remote syslog server. This feature is disabled by default. The Record will be generated for each call that is set up and terminated successfully, each call that is set up successfully but terminates abnormally without exchange of X.25 Clear packets, and each call that fails to set up.

IGMP Version 3

Support for the Internet Group Management Protocol Version 3 (IGMPv3) feature was added on the Cisco 87x and the Cisco 1800 series Integrated Services Routers (ISRs) and on EtherSwitch high-speed WAN interface cards (HWICs) and EtherSwitch network modules running on the Cisco 1841, 2800, and 3800 series ISRs.


Note Source Specific Multicast (SSM), IGMPv3 explicit host tracking, and IGMPv3 fast-leave processing are not supported on these platforms, EtherSwitch HWICs, and EtherSwitch network modules.


IGMPv3 provides supports for source filtering, which enables a multicast receiver host to signal to a router which groups it wants to receive multicast traffic from, and from which sources this traffic is expected. Enabling the IGMPv3 feature with IGMP snooping on Cisco ISRs provides Basic IGMPv3 Snooping Support (BISS). BISS provides constrained flooding of multicast traffic in the presence of IGMPv3 hosts. This support constrains traffic to approximately the same set of ports as regular IGMPv2 snooping does with IGMPv2 hosts. The constrained flooding only considers the destination multicast address.

In support of the IGMPv3 feature in Cisco IOS Release 12.4(15)T, the groups and count keywords were added to the show ip igmp snooping command and the output of the show ip igmp snooping command was modified to include global information about IGMP snooping groups. Use the show ip igmp snooping command with the groups keyword to display the multicast table learned by IGMP snooping for all VLANs or the show ip igmp snooping command with the groups keyword, vlan-id keyword, and vlan-id argument to display the multicast table learned by IGMP snooping for a specific VLAN. Use the show ip igmp snooping command with the groups and count keywords to display the number of multicast groups learned by IGMP snooping.

iLBC Support for SIP and H.323

The iLBC Supports for SIP and H.323 feature supports the internet Low Bitrate Codec (iLBC), a standard, high-complexity speech codec that is suitable for robust voice communication over IP. This codec is supported on both SIP and H.323.

For detailed information about this feature, see the "Dial Peer Overview" chapter and "Dial Peer Features and Configuration" chapter in Dial Peer Configuration on Voice Gateway Routers.

ISDN QEP

The ISDN QEP feature introduces the isdn layer2-flap command. When you include the isdn layer2-flap command in the ISDN configuration, the router (as a user agent) sends a RESTART or STATUS-ENQUIRY message to the remote peer when a Layer 2 flap and recovery occurs. This notification enhances the gateway's ability to gracefully recover from a Layer 2 flap or failure error condition. This graceful recovery frees gateway resources to handle future calls and to increase the call completion rate.

Use the isdn layer2-flap command with the isdn timer t309 command in your configuration. The isdn timer t309 command enables the router to hold or drop calls. The effect of using these two commands in the event of a Layer 2 flap and recovery is summarized as follows:

Layer 2 failure and then a Layer 2 recovery before the T309 timer expires (with T309 timer enabled)—STATUS-ENQUIRY message

Layer 2 failure and then a Layer 2 recovery after the T309 timer expires or with the T309 timer not enabled—RESTART message

USB eToken 64KB Smartcard Support

The Cisco universal serial bus (USB) eToken 64KB smartcard support feature enables device authentication and simplifies the deployment and secure configuration of Cisco routers. It uses smart card technology in a USB form factor to facilitate the authentication and configuration process. The token provides secure access to the route. The token and a PIN are necessary to access the configuration, keys, and credentials.

Some Cisco access router models have USB ports that can be used with Cisco USB flash memory modules or with the Aladdin USB eToken Pro key. These USB modules can be used with a supported Cisco access router for the following functions:

USB eToken Pro key provides a secure means of storing and deploying information, such as a bootstrap configuration or VPN credentials, apart from the router chassis. The USB eToken uses smart card technology to protect a small area of memory.

The USB eToken grants access using a personal identification number (PIN). When IP Security (IPSec) VPN credentials are stored on the USB eToken, they are outside the router. When the USB eToken is inserted in a USB port, and when the user enters the PIN and unlocks the USB eToken, the user retrieves the credentials and copies them into running memory. When the USB eToken is removed, the router erases the credentials from running memory, ensuring that they cannot be retrieved from the router itself.

NPE-G2 Network Processing Engine

The Network Processing Engine NPE-G2 is the latest and highest performing routing engine with largest scalability within the network processing engines family for the Cisco 7200VXR Series. A new chip design on the NPE-G2 offers up to double of the performance compared to the NPE-G1 network processing engine. This great performance improvement with the NPE-G2 makes it an ideal Cisco 7200 solution for new aggregation services for the enterprise as well as service provider segment.

The NPE-G2 offers following benefits:

Provides double the performance compared to the Cisco 7200 VXR NPE-G1—Up to 2 million packets per second (pps) in Cisco Express Forwarding (CEF)

Offers three 10/100/1000 Mbps copper Ethernet ports and optical ports (10/100/1000 Mbps over copper or 1000 Mbps over industry-standard SFP) for LAN/WAN connectivity

Provides two USB ports for general storage and security token storage

Provides one dedicated 10/100-Mbps copper Ethernet port for management

Offers 1 GB of DRAM memory by default and 2 GB DRAM is available as an option (which makes the Cisco 7200 Series, for example, ideal as Route Reflector, Master Controller of OER (Optimized Edge Routing), IP SLA, etc.)

Eliminates the requirement for an I/O controller

Extends the use of the available I/O slot for a single port adapter in combination with the Port Adapter Jacket Card (C7200-JC-PA) or a Cisco 7200VXR VPN Services Adapter (C7200-VSA)

Offers greatly improved price/performance ratio


Note An I/O controller module can be used with the NPE-G2, but it is not necessary for system functionality. Installing an I/O controller in a Cisco 7200VXR chassis with the NPE-G2 activates the console and auxiliary ports on the I/O controller and automatically disables the console and auxiliary ports the NPE-G2. However, you can still use the CompactFlash Disk slots and Ethernet ports on both the NPE-G2 and I/O controller when both cards are installed.


PA-MC-T3-EC and PA-MC-2T3-EC

The PA-MC-T3-EC is a single-width port adapter that comes in both a one-port version, PA-MC-T3-EC and two port version, PA-MC-2T3-EC. It supports both a channelized mode of operation, and an unchannelized mode of operation.

Cisco IOS Release 12.4(11)T supports the Cisco Quality ID feature in Cisco transceivers (Gigabit Interface Converter [GBIC] or small form factor pluggables [SFP]) on the NPE-G2 for Cisco 7200 VXR routers.

The Cisco Quality ID feature primarily consists of the following components: 1) a unique encrypted code in the GBIC module or SFP module which enables Cisco IOS to identify Cisco-pluggable parts, and 2) the ability of Cisco IOS to enable only those ports populated with Cisco parts. The Cisco Quality ID feature allows customers to have confidence that the GBIC modules or SFP modules being deployed are certified to be compatible with the Cisco network device in which they are being deployed.

HWIC-1ADSL Supporting the Cisco 1841, Cisco 2800 and Cisco 3800 Platforms

This is an incremental set of Quality of Service (QoS) features that allow customers to deploy differentiated services on ADSL/ADSL2/ADSL2+ lines with the HWIC-1ADSL WAN Interface Card (WIC) on the modular Cisco 1800, 2800 and 3800 series integrated services routers. This complements the rich set of IP and ATM QoS features already supported on the platforms with an ADSL2+ interface. These additional features allow users, applications and traffic to get appropriate Service Level Agreements (SLA) as well as provide service providers with opportunities for incremental revenue generation through differentiated services.

Today, QoS is an important infrastructure component that facilitates the widespread adoption of broadband in SMB and enterprise branch office environments. In response to customer requirements and pressures, network operators and service providers are finding it critical to offer QoS features for DSL deployments. This release enables service providers with their ADSL2+ deployments with a critical set of features such as:

Support for UBR+ class of service

Multi queue support

ATM oversubscription for DSL

UBR+ Support

Traditionally the unspecified bit rate (UBR) service class has been used for data communications applications such as file transfer and email. UBR is a best effort service and is the lowest class of service in the ATM service class hierarchy. There are no guarantees to the actual bandwidth allowed. Therefore, UBR virtual circuits (VCs) are susceptible to a large number of cell drops or a high cell transfer delay as cells move from the source to the destination. Unspecified bit rate plus (UBR+) is a special ATM service class designed to provide a minimum bandwidth guarantee. With UBR+, the ADSL ATM interface has the ability to assure a minimum as well as maximum bandwidth on the line. As a result, the user can have some assurance of a range of bandwidth values necessary for QoS.

Multiqueue Support

Today's access networks are increasingly carrying voice, video and data traffic over physical lines. Thus it is crucial for the access routers to honor latency, jitter and other requirements for delay sensitive traffic. The multiqueue feature provides for 2 separate hardware queues on the access router for every permanent virtual circuit (PVC) in the system, one to carry high priority and the other to carry regular (data) traffic.

ATM Oversubscription for DSL

Today, more and more business customers demand high availability in the networks. In many cases they use primary as well as secondary WAN interfaces for 24x7 connectivity. In ADSL networks, loss of connectivity may arise when the ADSL line is down or when the PVC is non-functional because of equipment failure in core networks. In order to overcome the challenges posed by the latter case, service providers are increasingly deploying primary and backup PVCs on the ADSL interface. However with a backup PVC, the configurable bandwidth requirement of all the PVCs in the system may be greater than the ADSL line rate. This may cause PVCs that need minimum bandwidth guarantees to be downgraded to a UBR class of service. The ATM Oversubscription feature allows the operator to configure oversubscription on the ADSL interface up to a defined bandwidth. The operator can configure variable bit rate (VBR) and unspecified bit rate plus (UBR+) service classes for PVC connections with a sum of sustainable cell rates (SCRs) greater than the line rate. Resource limitations on Cisco xDSL interfaces require a way to configure bandwidth oversubscription up to a defined bandwidth (a finite oversubscription of bandwidth by a factor of 2).

Smartports on ISR EtherSwitch

Smartports macros are supported in EtherSwitch network modules that are installed in a Cisco Integrated Service Router (ISR). The EtherSwitch network module is a high-density voice network module that provides Layer 2 switching across Ethernet ports. Smartports macros, also known as role-based macros, are sequences of CLI commands that enable features and configure settings on a switch port. Because they support an easily repeatable mechanism for enabling features and configuring settings, Smartports macros provide a simple method for configuring switch ports based on the location of the switch within the network. Smartports macros are also useful for customizing specific switch port configurations for mass deployment.

When you apply a Smartports macro on an EtherSwitch module or interface, the CLI commands within the macro are configured both on the target interface (or interfaces) and on any existing module or interface configurations. The new commands are added to the interface and are saved in the running configuration file.

Six default Smartports macros are provided as part of the Cisco IOS software. Each of these macros configures features suitable for connecting a switch port to a specific type of device:

The cisco-global global macro configures a switch in global configuration mode.

The cisco-desktop interface macro configures a port connected to a standard desktop.

The cisco-phone interface macro configures a port connected to a standard desktop and Cisco IP phone.

The cisco-router interface macro configures a port connected to a Cisco router.

The cisco-switch interface macro configures a port connected to a Cisco switch.

The cisco-wireless interface macro configures a port connected to a Wireless Access Point.

Although you cannot modify the default Smartports macros, you can create any number of customized Smartports macros. Customized macros can be tailored to define alternative or customized switch port configuration profiles.

VLAN.DAT to NVGEN

The VLAN.DAT to NVGEN feature enables you to save VLAN database configuration information for EtherSwitch network modules installed in a Cisco Integrated Service Router (ISR) in a single configuration file. The EtherSwitch network module is a high-density voice network module that provides Layer 2 switching across Ethernet ports. This feature enables network administrators of modular switches that contain VLAN information to back up the switch system in a single configuration file stored in NVRAM, rather than with multiple configuration files. With versions of Cisco IOS software prior to Release 12.4(11)T, VLAN database configuration information is stored in the compact flash memory in a VLAN.dat file and is not included in the startup configuration file. To save and restore a complete backup of a modular switch system with versions of Cisco IOS software prior to Release 12.4(11)T, you must manage both the startup configuration and VLAN.dat files.

With the introduction of this feature, an ISR EtherSwitch that uses the VLAN.DAT to NVGEN feature is in VTP server mode by default. When the switch is in VTP server mode, you can save the VLAN information to the VLAN.dat file only. To save the VLAN database configuration information to NVRAM instead, first use the vtp transparent global configuration command to set the device to the transparent VTP device mode; configuring the switch as VTP transparent disables VLAN Trunking Protocol (VTP) from the VTP management domain but does not remove the domain from the switch. Then configure VLAN information in the new config-vlan command mode. The VLAN database configuration information will be included in the startup configuration file that is generated by the nonvolatile generation (NVGEN) process invoked by the copy running-config command.


Note For backward compatibility, Cisco IOS software continues to support the original method, in which VLAN information is configured in global configuration mode and stored in a separate VLAN.dat configuration file.

FRF 1.2 Annex A Support

The FRF 1.2 Annex A Support feature is also called Local Management Interface (LMI) segmentation. It supports an enhancement to the Frame Relay LMI protocol by which LMI full status messages are segmented because of MTU constraints or large numbers of permanent virtual circuits (PVCs). This feature is useful when the maximum MTU size is insufficient to accommodate the large number of PVCs on the link. During Frame Relay internetworking with other Layer 2 protocols, the MTUs on each interface must match. In software that does not have the FRF 1.2 Annex A Support feature, you cannot change the MTU size on the Frame Relay side and place all PVC data in one LMI packet. The FRF 1.2 Annex A Support feature removes this limitation.

The FRF 1.2 Annex A standard adds a new message type "Full status continued" to an LMI packet. When a DCE determines that it cannot fit all PVCs into one packet (enforced by the MTU size), the message type is set to "Full status continued." The DTE responds immediately to "Full status continued" messages that are sent to this packet instead of waiting for the T391 timer to expire. The DCE sends the remaining PVCs in one or more "Full status continued" messages until all the remaining PVCs can fit into one message. At this point, a normal "Full status" message is sent.

If the DTE receives a "Full status" or "Full status continued" STATUS message in response to a "Full status continued" STATUS ENQUIRY message, this exchange indicates a lower-valued data-link connection identifier (DLCI) than the prior "Full status continued" STATUS message (and is considered to be an error event), and PVC information elements (IEs) are not processed. The next time the T391 timer expires, the "Full status" STATUS ENQUIRY procedure is reinitiated.

This feature follows the FRF 1.2 implementation agreement and allows Cisco IOS software to be compliant with the FRF 1.2 standard. The implementation is platform-independent and applies to all platforms running Cisco IOS software that support Frame Relay. This feature interoperates only with existing Cisco IOS software releases in which all PVCs can be reported in one packet. A router running the new functionality must be able to interoperate with routers that are running existing Cisco IOS software releases and with routers that support the new functionality using the continuation status request and reply frames. Only LMI types Q.933A and ANSI support the FRF 1.2 Annex A standard.

You can track "Full status continued" packets by using the debug frame-relay lmi command in privileged EXEC mode. An extra field, 04, has been added to the display output (the last row in the following example indicates where in the report to look for this field):

17:42:39: Serial1(out): StEnq, myseq 126, yourseen 125, DTE up 
17:42:39: datagramstart = 0x40058DA4, datagramsize = 13 
17:42:39: FR encap = 0x00010308 
17:42:39: 00 75 51 01 04 53 02 7E 7D 
 
   

The string segment "active/inactive" in the display of the show interface commands indicates whether the FRF 1.2 Annex A standard is triggered. The report indicates active when routers receive the "Full status continued" message; otherwise, the report indicates inactive.

Port Adapter Jacket Card

Port Adapter Jacket Card

The Port Adapter Jacket Card addresses the demand for additional slot density and flexibility on the Cisco 7200VXR Services Aggregation Series by enabling the I/O controller card slot to hold a single (selected) port/service adapter for additional capacity on systems with the Cisco 7200VXR Series NPE-G1 Network Processing Engine and above.

Benefits of the Port Adapter Jacket Card include the following:

Provides one additional slot for single port/service adapter (selected port/service adapters)

Allows a high-bandwidth port adapter—such as the hardware based security encryption module SA-VAM2+ and the 2-Port Packet/SONET OC3c/STM1 Port Adapter—to be moved onto a dedicated Peripheral Component Interconnect (PCI) bus that the Cisco NPE-G1 or NPE-G2 provides

Reduces PCI contention among other port adapters

Provides a cost-effective way to increase the slot density in parallel to the increased switching capacity of the newest engine for the Cisco 7200VXR series—the Cisco NPE-G2

SSHv2 for RPM-XF

Secure Shell (SSH) is an application and a protocol that provides a secure replacement to the Berkeley r-tools. The application is similar to the Berkeley rexec and rsh tools. The protocol secures the sessions by using standard cryptographic mechanisms. Two versions of SSH are available: SSH Version 1 and SSH Version 2. Cisco IOS Release 12.4(6)T implements SSH server and client for both versions. You must have the RPM-XF crypto image installed to use the SSH feature.

The SSH feature on the RPM-XF is useful if you want to manage the card through its management or high-speed back card. More often however, you manage the RPM-XF, and all other cards in the MGX chassis, from the PXM45 controller. The PXM45 controller also implements SSH and provides the same level of security.

If you plan to use SSH on the RPM-XF, consider disabling Telnet access to improve security. Telnet transfers all user ID, password, and session management information between the client and the RPM-XF by using clear text. Clear, or unencrypted text can be read by network analysis and snooping tools.

To use SSH the first time, you must activate the SSH server. You can then enable or disable SSH, or other management protocols, on the asynchronous (vty) ports. You enable the SSH server and configure SSH ports on the RPM-XF as you would other Cisco routers running Cisco IOS Release 12.4(6)T.

Enhancing CISCO-H225-MIB with Disconnect Cause Codes

The CISCO-H225-MIB was enhanced with the Q.931 disconnect cause codes that the H.323 subsystem can receive. A disconnect can originate from the far-end gateway or from the opposite call leg on the local gateway. This enhancement to the MIB allows you to report disconnect cause code information, including the cause code type and the number of cause code disconnects received from either H.323 peer. The enhancement corresponds to the usage of the show h323 gateway command. See the show h323 gateway command for an example of the disconnect cause code display.

The Enhancing CISCO-H225-MIB with Disconnect Cause Codes feature provides SNMP MIB enhancements on the following platforms:

Cisco AS5350 series universal gateways

Cisco AS5400 series universal gateways

Cisco AS5850 universal gateways

The MIB contains objects that represent active H.323 calls and also includes call details. For definitions of the H.323 MIB objects, see the following MIBs:

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.

IPv6 IPsec Router-to-Router Tunnels

For detailed information about this feature, see the following:

http://www.cisco.com/en/US/docs/ios/ipv6/configuration/guide/ip6-fhrp.html

L2TP Tunnel Selection Load Balancing with Random Algorithm

The L2TP Tunnel Selection Load Balancing with Random Algorithm feature introduces an improved algorithm for load balancing Layer 2 Tunnel Protocol (L2TP) sessions when a network access server (NAS) must choose between multiple peer tunnel servers. For information about configuring L2TP load balancing, refer to the "Configuring L2TP Tunnel Server Load Balancing and Failover Using the RADIUS Tunnel Preference Attribute" section of the Cisco IOS VPDN Configuration Guide, Release 12.4T.

When multiple tunnel servers of the same priority are configured, the NAS will select the tunnel server with the lowest number of active sessions. If several tunnel servers have the same number of active sessions, the NAS must use a tie-breaking mechanism to determine which to select.

In Cisco IOS releases prior to 12.4(4)T, the NAS uses a round-robin selection as the tie-breaking mechanism. Because each NAS is aware only of its own session load, multiple NASs using the same round-robin algorithm may unevenly distribute sessions across the tunnel servers (session bunching). Each NAS selects the same tunnel server in the case of a tie because the round-robin tie-breaking mechanism always resolves to the same tunnel server. Session bunching is especially prominent when there is a very low number of sessions on each NAS.

Beginning in Cisco IOS Release 12.4(4)T, the NAS uses a new tie-breaking algorithm. A random selection is made among all peer tunnel servers carrying the same session load. This improved algorithm results in a more even distribution of sessions across tunnel servers, reducing the occurrence of session bunching.

E1 R2 Collect Call Blocking

The E1 R2 Call Blocking feature provides two ways to block incoming collect calls: category-based and double answer. With category-based call blocking, collect calls are blocked based on a specific category. For example, in Brazil, collect calls arrive with a category II-8, for which the Cisco access router sends B-7 as a response instead of an answer signal. This approach is only applicable when switches in the central office support category-based blocking.

For legacy switches that do not support category-based blocking, the double answer method is implemented on the Cisco 2801 router to support the collect-call blocking. For an incoming collect call, the gateway answers the call with a clearback after one second and re-answers the call after two seconds, causing the collect call to be dropped and normal calls to stay connected. This can be implemented as a command-line interface (CLI) option for any country. See the cas-custom command at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios124/124cr/hdia_r/dia_a1h.htm#wp1080542

Secure Communication Between IP-STE Endpoint and Trunkside STE Endpoint

This feature supports encrypted and decrypted calls from IP secure terminal equipment (STE) controlled by Cisco CallManager through a voice gateway to an STE in the Defense Switching Network. This feature implements a subset of the V.150.1 modem relay standard, allowing users to operate U.S. Department of Defense-compliant (Type-1 encryption) devices across a VoIP network, and between VoIP networks and the Defense Switching Network.

Single Source Infrastructure Phase IV

The Single Source Infrastructure Phase IV feature incorporates infrastructure dependencies in order to enable the migration of the Enhanced Interior Gateway Routing Protocol (EIGRP) to a true single source component.

SIP: Domain Name Support in SIP Headers

The SIP: Domain Name Support in SIP Headers feature adds a command-line interface (CLI) switch to provide a host or domain name in the host portion of the locally generated session initiation protocol (SIP) headers (for example, From, RPID, and Call-ID). The SIP: Domain Name Support in SIP Headers feature also affects the outgoing dialog initiating SIP requests (for example, INVITE and SUBSCRIBE message requests).

SIP: Multilevel Precedence and Priority Support

The SIP: Multilevel Precedence and Priority Support feature enables Cisco IOS gateways to interoperate with other multilevel-precedence and preemption (MLPP)-capable circuit-switched networks.

An MLPP-enabled call has an associated priority level that applications that handle emergencies and congestions use to determine which lower-priority call to preempt in order to dedicate their end-system resources to high-priority communications. This feature addresses the aspect of preemption when interworking with defense-switched networks (DSNs) that are connected through the Cisco IOS gateway.

SIP Stack Portability

The SIP Stack Portability feature implements the following capabilities to the session initiation protocol (SIP) gateway Cisco IOS stack:

It receives inbound REFER message requests both within a dialog and outside of an existing dialog from the user agents (UAs).

It sends and receives SUBSCRIBE or NOTIFY message requests via UAs.

It receives unsolicited NOFITY message requests without having to subscribe to the event that was generated by the NOTIFY message request.

The portable stack supports outbound delayed media.

It sends an INVITE message request without Session Definition Protocol (SDP) and provides SDP in either the PRACK or ACK message request for both initial call establishment and midcall re-INVITE message requests.

It sets SIP headers and content body in requests and responses.

The stack applies certain rules and restrictions for a subset of headers and for some content types (such as SDP) to protect the integrity of the stack's functionality and to maintain backward compatibility. When receiving SIP message requests, it reads the SIP header and any attached body without any restrictions.

SIP: User Agent MIB Enhancements

The SIP: User Agent MIB Enhancements feature provides SNMP MIB object enhancements to the CISCO-SIP-UA-MIB and informational updates to the CISCO-SIP-UA-CAPABILITY file. The CISCO-SIP-UA-CAPABILITY file provides information such as the Cisco IOS release number and the capabilities of the CISCO-SIP-UA-MIB. The SIP: User Agent MIB Enhancements feature is available on the following Cisco platforms:

Cisco AS5350 universal gateways

Cisco AS5400 series universal gateways

Cisco AS5850 universal gateways

Cisco CVA120 series cable voice adapters

Cisco IAD2430 series integrated access devices

Cisco uBR925 cable access routers

Cisco 1750, Cisco 1751, Cisco 1760

Cisco 1751-V

Cisco 2610XM, Cisco 2611XM, Cisco 2620XM, Cisco 2621XM, Cisco 2650XM, Cisco 2651XM

Cisco 2801, Cisco 2811, Cisco 2851, Cisco 2821

Cisco 3640, Cisco 3640A, Cisco 3660

Cisco 3825, Cisco 3845

Cisco 3725, Cisco 3745

Cisco 7200 series

The SIP: User Agent MIB Enhancements feature provides SNMP MIB object configuration and counter support that are equivalent to command-line interface additions introduced in the following features:

SIP Call Admission Control Support

SIP Call Transfer Enhancements Using the Refer Method

SIP Cisco IOS Gateway Reason Header and Buffered Calling Name Completion

SIP: Gateway HTTP Authentication Digest

SIP Gateway Support Enhancements to the bind Command

SIP Header/URL Support and Subscribe/Notify for External Triggers

SIP Hold Timer Support

SIP ISDN Suspend/Resume Support

SIP PSTN Transport Using Cisco's Generic Transparency Descriptor (GTD)

SIP RFC 3261 Enhancements (RFC 3261)

In addition, the SIP: User Agent MIB Enhancements feature provides two new MIB objects. In Release 12.3(4)T, the SIP Gateway Support Enhancements to the bind Command feature extended the Cisco IOS bind command by adding the media keyword. The media keyword allows multiple instances of the bind command. One instance defines the control address, and one instance defines the media address. Because the original CISCO-SIP-UA-MIB was defined with a single instance of the bind command, the MIB objects that support the bind command will be replaced with two new MIB objects that support multiple instances.

Any SNMP applications that SET or GET the following objects from the CISCO-SIP-UA-MIB:

cSipCfgBindSrcAddrScope

cSipCfgBindSrcAddrInterface

need to refer to the new objects. Although these objects have not been removed and are still accessible with Release 12.4(2)T, they will be removed in a future release. Users must upgrade any affected application to the following new objects:

cSipCfgBindSourceAddrScope. This object can have a value of either media (1) or control (2).

cSipCfgBindSourceAddrInterface. This object can have any value of the integer interface index.

You can specify pairs of cSipCfgBindSourceAddrInterface and cSipCfgBindSourceAddrScope objects. Specifying pairs allows you to associate one interface address with control traffic and another interface address with media traffic.


Note "Src" in the prior objects has been replaced with "Source" in the new objects.


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

SSG—Limiting the Number of Sessions and Services

For detailed information about this feature, see the following:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios124/124newft/124t/124t2/ht_maxcn.htm

SSG Support of RADIUS Disconnect Message

Service Selection Gateway (SSG) supports the RADIUS disconnect message, as specified in RFC 3576—Dynamic Authorization Extensions to Remote Authentication Dial In User Service (RADIUS). This message enables the billing server to request SSG to disconnect an active session.

When SSG receives a disconnect request with a RADIUS code of 40, it disconnects the user and deletes all information related to the host object. For Transparent Auto Logon (TAL) users, SSG deletes the Transparent pass-through (TP) entry. SSG identifies the host based on attribute 8 (framed-ip address) or the vendor-specific attribute (VSA) ssg account-info with subattribute S in the disconnect request. In host key overlap mode, the ssg account-info VSA is required to process the disconnect request. Inactive hosts will not be deleted.

For RADIUS proxy users, SSG deletes the host but does not forward the disconnect request to the downstream devices. The authentication, authorization, and accounting (AAA) RADIUS server forwards the disconnect request to the downstream devices, which removes all the session information.

SSG Support of WISPr Location Attributes

For detailed information about this feature, see the following:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios124/124newft/124t/124t2/ht_wispr.htm

SSG Transient Stateful Host Object

The Microsoft 2000 operating system performs a Dynamic Host Configuration Protocol (DHCP)-Renew when it receives an IP address. An Access Zone Router (AZR) interprets the DHCP-Renew action as a client disconnect. As a result, the AZR sends an Accounting-Stop message to the Service Selection Gateway (SSG) device. The SSG device deletes the host object and all its associated connections, including the ProxyLogonAttrs. When SSG subsequently receives an Accounting-Start message with an IP address, SSG does not have authenticated ProxyLogonAttrs for the WLAN user. SSG creates IPUserAttrs for this user and waits for the user to log in to the Subscriber Edge Services Module (SESM). However, in some situations, SESM does not exist; all services are auto-services. In such cases, the WLAN user cannot log in. Even if the user resets the wireless connection and reauthenticates, the user still cannot log in.

Cisco IOS Release 12.4(2)T introduces an enhancement that accommodates DHCP-Renew actions without causing a complete disconnect. When the SSG device receives an Accounting-Stop message, it retains the host object and puts it in an inactive state. The SSG device waits an amount of time for an Accounting-Start message with an IP address from the AZR. (The IP address timer specifies the amount of time to wait.) If the SSG device receives the Accounting-Start message from the AZR within the specified time, the SSG device activates the host object. If the SSG device does not receive the Accounting-Start message within the specified amount of time, it then deletes the host object. This enhancement improves the call flow between the AZR and the SSG device.


Note This enhancement does not apply to open authentication scenarios (no EAPSIM authentication). SSG deletes the host object when it receives an Accounting-Stop message from the AZR. The WLAN user can log back in to the SESM.

Limitations and Restrictions

Limitations and Restrictions for Cisco IOS Release 12.4(20)T

The following sections contain limitations and restrictions that apply to Cisco IOS Release 12.4(20)T.

Cisco 3200 Router

Cisco IOS Release 12.4(15)XZ introduced CU-CME support on the Cisco 3230/3250 and Cisco 3270 router platforms. Due to memory size limitations on the Cisco 3230/3250 router card, CUCME feature enhancements will be limited to Cisco IOS Release 12.4(15)XZ and Cisco IOS Release 12.4(20)T. Customers that wish to activate CUCME on the Cisco 3230/3250 will need to use the Adventerprisek9 Cisco 3230/3250 image based off Cisco IOS Release 12.4(15)XZ.

The Cisco 3270 platform will continue to support additional CUCME feature enhancements beyond the Cisco IOS Release 12.4(15)XZ. Reference the CUCME technical guides for new feature support on the Cisco 3270 platforms in future CUCME releases.

Limitations and Restrictions for Cisco IOS Release 12.4T

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

802.1x Limitations

The Cisco ISR platforms (800, 1800, 2800) support most of the 802.1x features, but not all of the features are supported. For example, unidirectional 802.1x with the dot1x control-direction command is not supported on these platforms. This command is not supported in Cisco IOS Release 12.4T.

cTCP and VSA Restriction

Cisco Tunnel Control Protocol (cTCP) is not supported on VPN Services Adapter (VSA).

Cisco IOS Firewall Instant Messenger Support Restriction

Cisco IOS firewall supports only the following versions of each Instant Messenger (IM) application:

Yahoo Messenger supported versions: 6.0.0.1922, 6.0.0.1750, 6.0.0.1671, and 6.0.0.1643

MSN supported versions: 6.2.0205 and 7.0.0816

AOL supported version: 5.9.3702


Note All other IM version connections will be reset.


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 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.

Important Notes for Cisco IOS Release 12.4(24)T

The following information applies to all releases of Cisco IOS Release 12.4(24)T.

Cisco IOS Voice Command Reference

The authenticate redirecting-number command and voice-class sip authenticate redirecting-number command are added to the Cisco IOS Voice Command Reference. Use these commands to configure the number that dial peers on a Cisco IOS voice gateway use to authenticate and pass SIP credentials.

Old behavior: If these commands are not configured, all dial peers on the gateway authenticate and pass SIP credentials based always on the calling number.

New behavior: You can specify, for any or all dial peers on a Cisco IOS voice gateway, the number used to authenticate and pass SIP credentials. You can enable one or both of the authenticate redirecting-number commands to specify that one or more dial peers on the gateway authenticate and pass SIP credentials based on the redirecting number if available. When the redirecting number is not available, the calling number is used. (The redirecting number is available only in the headers of forwarded calls.)
