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
The L2TP Congestion Avoidance feature provides packet flow control and congestion avoidance by throttling Layer 2 Transport Protocol (L2TP) control messages, as described in RFC 2661. For detailed information about this feature, see the following:

The L2TP Forwarding of PPPoE Tag Information feature allows you to identify and uniquely map subscribers to Point-to-Point Protocol over Ethernet (PPoE) sessions through the subscriber's remote ID. This feature passes subscriber information collected on the Digital Subscriber Line Access Multiplexer (DSLAM) through to the Line Network Server (LNS) using a Layer 2 Tunneling protocol (L2TP) attribute-value (AV) pair. For detailed information about this feature, see the following:

Mobile IP Route Propagation Within VRF on Home Agent
The Home Agent supports overlapping IP addresses for mobile nodes for the mobile IP flows that are opened for different realms. This feature is based on the Multi-VPN Routing and Forwarding (VRF) CE network architecture and expands the BGP/MPLS VPN architecture to support multiple VPNs per Customer Edge (CE) device.
In the Cisco Home Agent Release 3.0, the VRF feature is enhanced to configure the network access identifier (NAI) to VRF mapping on the RADIUS server.

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.

ADSL2/2+ Annex M support on CISCO 877-M, CISCO 1801-M, and HWIC-1ADSL-M
The Asymmetric Digital Subscriber Line (ADSL) 2/2+ Annex M feature supports routed bridge encapsulation over VC bundles on specific platforms in Cisco IOS Release 12.4(11)XJ. ADSL 2/2+ Annex M supports an upstream data rate of up to 3 Mbps and a downstream data rate of up to 24 Mbps. The increase of the Annex M (upstream) data rate is achieved by using some of the tones that were previously used in the downstream data rate in Annex A. As a result, downstream data rates are decreased in Annex M.
The ADSL training log generation command, dsl-enable-training-log, has been enhanced to specify the time when to capture a log file. This command enables the training log to record firmware debug messages.

http://www.cisco.com/univercd/cc/td/doc/product/software/ios122sr/newft/122sra33/srethoam.htm
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
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:

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:
•
•
•
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:
•
•
•
•
•
•
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.

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 up17:42:39: datagramstart = 0x40058DA4, datagramsize = 1317:42:39: FR encap = 0x0001030817:42:39: 00 75 51 01 04 53 02 7E 7DThe 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.

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:
•
•
•
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:
•
•
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.

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 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.
•
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:
•
•
•
•
•
•
•
•
•
•
•
•
•
•
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:
•
•
•
•
•
•
•
•
•
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:
•
•
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:
•
•
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
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.

MIBs
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
If Cisco MIB Locator does not support the MIB information that you need, you can also obtain a list of supported MIBs and download MIBs from the Cisco MIBs page at the following URL:
http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml
To access Cisco MIB Locator, you must have an account on Cisco.com. If you have forgotten or lost your account information, send a blank e-mail to cco-locksmith@cisco.com. An automatic check will verify that your e-mail address is registered with Cisco.com. If the check is successful, account details with a new random password will be e-mailed to you. Qualified users can establish an account on Cisco.com by following the directions found at this URL:

Deprecated and Replacement MIBs
Old Cisco MIBs will be replaced in a future release. OLD-CISCO-* MIBs are being converted into more scalable MIBs without affecting existing Cisco IOS products or network management system (NMS) applications. You can update from deprecated MIBs to the replacement MIBs as shown in Table 1.
Limitations and Restrictions
The following sections contain limitations and restrictions that apply to 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:

Note
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.
