Introduction
The Cisco ASR 1000 Series Aggregation Services Routers are the next generation Cisco midrange router products. The Cisco ASR 1000 Series Aggregation Services Routers use an innovative and powerful hardware processor technology known as the Cisco QuantumFlow Processor. The Cisco ASR 1000 Series Routers consist of three different routers: the Cisco ASR 1002 Router, the Cisco ASR 1004 Router, and the Cisco ASR 1006 Router.
•
•
•
For the single-route-processor Cisco ASR 1000 platforms, the Cisco ASR 1002 and Cisco ASR 1004, the Route Processor has a dual Cisco IOS Software option that allows these routers to use Cisco IOS software redundancy, Cisco high-availability features, Nonstop Forwarding (NSF), and In Service Software Upgrades (ISSUs). This option requires the Cisco ASR 1000 Series Route Processor to have 4 GB of DRAM memory.
The Cisco ASR 1006 Router supports fully redundant Route Processors that allow for full Route-Processor hardware redundancy, NSF, ISSU, and future Route-Processor service upgrades.
The Cisco ASR 1000 Series Routers run Cisco IOS XE Software and introduce a distributed software architecture that moves many operating system responsibilities out of the IOS process. In this architecture, Cisco IOS, which previously was responsible for almost all of the internal software processes, now runs as one of many Cisco IOS XE processes while allowing other Cisco IOS XE processes to share responsibility for running the router.
One of the key features of the Cisco IOS XE Software is support for dual Cisco IOS software consolidated packages in a single Route Processor for software redundancy in the 2-RU and 4-RU chassis systems. These dual Cisco IOS consolidated packages can consist of the same software consolidated packages for backup or different software consolidated packages for resilient upgrade.
Note
The Cisco ASR 1000 Series Routers target both enterprise and service provider applications and provide application-specific features for broadband subscriber aggregation and network application services with improved processing performance and high availability.
For information on new features and Cisco IOS commands supported by Cisco IOS XE Release 2, see the "New and Changed Information" section and the "Related Documentation" section.
System Requirements
This section describes the system requirements for Cisco IOS XE Release 2 and includes the following sections:
•
•
•
•
Software Packaging on the Cisco ASR 1000 Series Routers
The Cisco ASR 1000 Series Routers run Cisco IOS XE Software and use a new software packaging model consisting of:
•
•
•
Each Cisco IOS XE consolidated package contains a collection of individual software sub-packages. Each individual software sub-package is an individual software file that controls a different element or elements of the Cisco ASR 1000 Series Router. Some individual sub-packages may be installed per element (for example, per SPA).
Note
Each individual software sub-package can be upgraded individually, or all individual software sub-packages for a specific Cisco IOS XE consolidated package can be upgraded as part of a complete Cisco IOS XE consolidated package upgrade.
Importantly, IOS (the RPIOS individual software sub-package) is considered one of the individual software sub-packages that makes up the complete Cisco IOS XE consolidated package.
The following are the individual software sub-packages within a consolidated package:
•
–
–
–
Note
–
•
–
•
–
–
A Cisco IOS XE consolidated package allows users to upgrade all individual software sub-packages on the router with a single Cisco IOS XE image download. The Cisco IOS XE consolidated packages available vary based on the Route Processor (RP1 or RP2) installed in the system and the Cisco IOS XE Release.
The following are the RP1 consolidated packages:
•
•
•
•
•
•
Note
The Cisco ASR 1000 Series RP1 ADVANCED ENTERPRISE SERVICES W/O CRYPTO consolidated package is only available beginning with Cisco IOS XE Release 2.2.1 and later releases. This consolidated package is not available with Cisco IOS XE Release 2.1.2 and earlier releases.The following are the RP2 consolidated packages:
•
•
•
•
•
•
Note
The Cisco ASR 1000 Series RP2 ADVANCED IP SERVICES W/O CRYPTO consolidated package is only available with Cisco IOS XE Release 2.3.0 through Cisco IOS XE Release 2.3.x. This consolidated package is not available with any other Cisco IOS XE Releases.The individual software sub-packages within the consolidated packages cannot be downloaded from Cisco.com; only the Cisco IOS XE consolidated packages and optional sub-packages can be downloaded from Cisco.com. Users who want to run the router using individual software sub-packages must first download the consolidated package from Cisco.com and extract the individual software sub-packages from the consolidated package.
In addition to the individual software sub-packages within a consolidated package, optional software sub-packages that are not part of a consolidated package are available. Optional software sub-packages are downloaded separately from Cisco.com and their installation is similar to the installation of an individual software sub-package using a provisioning file. The optional sub-package must be located in the same directory with the provisioning file and the other individual sub-package files. The optional software sub-packages available vary based on the Route Processor (RP) installed in the system: RP1 or RP2:

Note
For further information on the advantages and disadvantages of running individual sub-packages or a complete Cisco IOS XE consolidated package, and the process of extracting the individual sub-packages, see the following document:
Cisco ASR 1000 Series Aggregation Services Router Software Configuration Guide at the following location:
http://www.cisco.com/en/US/docs/routers/asr1000/configuration/guide/chassis/asrswcfg.html
RP Memory Recommendations
The Cisco IOS XE images and packages available vary based on the Route Processor (RP) installed in the system: RP1 or RP2.
•
•
•
•
Each Cisco IOS XE image also contains two provisioning files: asr1000rpx-packages.image.version.conf and packages.conf. A provisioning file is used for booting only in cases where the individual modules are extracted from the Cisco IOS XE image and then used to run the router. Either provisioning file can be used.

New Hardware Features in Cisco IOS XE Release 2.4.0
The following new hardware features are supported by the Cisco ASR 1000 Series Routers for Cisco IOS XE Release 2.4.0:
Cisco ASR 1002-Fixed Router
The Cisco ASR 1002-Fixed (Cisco ASR 1002-F) Router is the smallest of the Cisco ASR 1000 Series Aggregation Services Routers and supports all the general-purpose routing and security features of the Cisco ASR 1002 Router.
The Cisco ASR 1002-F Router uses the same internal control and data-plane architecture as the Cisco ASR 1002 router with the following variations:
•
•
•
For information about the Cisco ASR 1002-F Router, see the following documents:
Cisco ASR 1000 Series Aggregation Services Routers Hardware Installation Guide at the following location:

New Shared Port Adapters
Cisco IOS XE Release 2.4.0 introduces support for the following new shared port adapters (SPAs):
POS SPAs
•
•
•
•
Services SPA
•
The Cisco WebEx Node for ASR 1000 Series is a full-height SPA designed to run an application which is part of the WebEx MediaTone network management application. The Cisco WebEx Node for ASR 1000 Series improves the functionality of WebEx meeting services by adding the meeting servers into the SPA itself. This technology provides the following advantages:
–
–
–
By moving the switching components of the WebEx Collaboration Cloud into the Cisco WebEx Node for ASR 1000 Series, the WebEx clients in the enterprise network need only connect to the Cisco WebEx Node for ASR 1000 Series. This reduces the traffic between the enterprise network and the WebEx MediaTone network, greatly reducing the customer's Internet bandwidth requirements.
Each Cisco WebEx Node for ASR 1000 Series can be configured to perform either web conferencing or voice and video conferencing, but not both features at the same time. Each Cisco WebEx Node for ASR 1000 Series uses the same software package that includes both features; the conferencing feature that actually runs on each SPA is determined by the WebEx Service Plan the customer has purchased. The WebEx MediaTone network retains the Cisco WebEx Node for ASR 1000 Series configuration files that the SPA retrieves each time the SPA boots. Multiple Cisco WebEx Nodes for ASR 1000 Series can be installed on the same Cisco ASR 1000 Series Router chassis to increase the conferencing performance or to provide conferencing coverage for both web and voice and video sessions.
For information about the SPAs supported on the Cisco ASR 1000 Series Routers, see the following documents:

Etherchannel Flow Based Limited 1:1 Redundancy
The EtherChannel Flow-Based Limited 1:1 Redundancy feature provides a way to configure load balancing at the port-channel level based on different flows of traffic. You can identify different flows of traffic based on key fields in the data packet and balance the traffic load according to those traffic flows. To use EtherChannel flow-based limited 1:1 redundancy, you configure an EtherChannel with two ports (one active and one standby). If the active link goes down, the EtherChannel stays up and the system performs fast switchover to the hot-standby link. When the failed link becomes operational again, the EtherChannel performs another fast switchover to revert to the original active link.

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 memory, Cisco IOS software allows CRLs either to be stored in cache after being processed or to be decoded. Configuring the CRL cache size allows the amount of memory to be decreased (for example, if low memory conditions exist) or to be increased (for example, when a large number of CRLs are being processed), resulting in better performance.
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.

Cisco Firewall and WAAS Inter-Op
The Cisco Firewall and WAAS Interoperability feature enables a router configured with a firewall to successfully communicate with a cache engine, such as a Wide Area Application Acceleration (WAAS) device that is using the Web Cache Communication Protocol (WCCP).
WAAS optimizes remote access to applications.When the cache engine is a WAAS device, it can optimize TCP flow by modifying TCP headers. During the TCP three-way handshake, the WAAS device can add an extra TCP option in the header to indicate that the flow will be optimized. When the TCP session is established, the WAAS device can modify the sequence and acknowledge number in the TCP header to optimize the data flow.
When a Cisco firewall is configured on the router, the packets have to be inspected by the firewall. Depending on the deployment scenario, the firewall inspects packets as follows:
•

Integrated Session Border Controller
Cisco IOS XE Release 2.2.1 introduces support for the following new Integrated Session Border Controller (SBC) features:
•
•
•
•
•
Full Support for Wildcard Response
Previously Session Border Controller (SBC) supported H.248 wildcard operations that were restricted to W-Modify or W-Subtract requests, which yielded summary wildcard responses. This feature introduces support for a complete wildcard response. A wildcard H.248 Subtract or Modify operation now returns a complete response with per-termination statistics.
H.248 Protocol—Acknowledgment Support for Three-Way Handshake
The data border element (DBE) supports a three-way handshake for H.248 messages. The DBE supports sending of an acknowledgement for a three-way handshake after receiving the transaction response from the media gateway controller (MGC), as described in Annex D.1.2 and Annex D.1.2.2 of H.248.1 v3 Gateway Control Protocol.H.248 ServiceChange Handoff
The ServiceChange Handoff functionality on Integrated Session Border Controller conforms to section 7.2.8, ServiceChange, and section 7.2.8.1.1, ServiceChangeMethod, of the H.248.1 v3 Gateway Control Protocol. The ServiceChange Handoff functionality allows a media gateway controller (MGC) to hand over control of a media gateway (MG) to another MGC. The MGC sends a ServiceChange message to the MG that it is currently associated with to request that the MG terminate that association and the MG form a new association with an MGC identified in the ServiceChange message.
Improved Media Timeout Detection
In the previous media timeout functionality on the data border element (DBE), if no SBC packets have been seen by the configured number of seconds since the call has been established, then the DBE generates a media timeout alert to the SBE. The Improved Media Timeout Detection feature delays reporting of the media timeout event by instructing the DBE to wait until it has received the first packet since the call has been established. Only then does the media timeout timer start counting the number of seconds for which it has not seen an SBC packet. At the end of the count, the DBE generates an alert to the SBE.
Interim Authentication Header Full Support
Integrated SBC offers full support of Interim Authentication Header (IAH) that conforms to section 10.2, Interim AH Scheme, of the H.248.1 v3 Gateway Control Protocol. An IAH is part of every H.248 message generated by the data border element (DBE) to the media gateway controller (MGC). Information in the IAH is used to authenticate and check the integrity of packets, thus ensuring packet security. The DBE generates an IAH for outgoing H.248 messages and can verify the Authentication Header for incoming H.248 messages. The IAH scheme inserts the IAH within the H.248.1 protocol header.IPSec Pinhole Support—Twice NAT for IPv4 and No NAT for IPv6
The IPSec Pinhole Support—Twice NAT for IPv4 and No NAT for IPv6 feature adds support for voice calls over IPSec tunnels and adds support for IPSec address-only pinholes. This support enables the DBE to forward IPSec packets when the port cannot be determined because the port is within the encrypted portion of the frame. Thus, IPSec support handles the IPSec requirement that does not allow use of port numbers for session lookup or translation. Currently single IPSec pinholes are supported, whereby both IKE and the encrypted IPSec traffic passes through the same pinhole.
For information about these SBC features, see the following document:
http://www.cisco.com/en/US/docs/routers/asr1000/configuration/guide/sbc/2_xe/sbc_2_xe_book.html

L2TP HA Session SSO/ISSU on LAC/LNS
The L2TP HA Session SSO/ISSU on a LAC/LNS feature provides a generic Stateful Switchover/In Service Software Upgrade (SSO/ISSU) mechanism for Layer 2 Tunneling Protocol (L2TP) on a Layer 2 Access Concentrator (LAC) and a Layer 2 Network Server (LNS). This feature preserves all fully-established Point-to-Point Protocol (PPP) and L2TP sessions (including Multihop) during an SSO switchover, or an ISSU upgrade or downgrade.
For information about this feature, see the following document:
http://www.cisco.com/en/US/docs/ios/vpdn/configuration/guide/l2tp_sso.html
L3 MPLS VPN Over GRE
L3 MPLS VPN over GRE provides a mechanism for tunneling Multi Protocol Label Switching (MPLS) packets over a non-MPLS network.
The L3 MPLS VPN over GRE feature utilizes MPLS over Generic Routing Encapsulation (MPLSoGRE) to encapsulate MPLS packets inside IP tunnels; thus creating a virtual point-to-point link across non-MPLS networks. This allows users of primarily MPLS networks to continue to use existing non-MPLS legacy networks until migration to MPLS is possible.

Per Subscriber Firewall on LNS
The Per-Subscriber Firewall on LNS feature enables the zone-based policy firewall configuration model to be implemented on the Cisco ASR 1000 Series Router. Zone-based policy firewall is a unidirectional firewall policy between groups of interfaces known as zones. (Previously, Cisco firewalls were configured as an inspect rule only on interfaces. Traffic entering or leaving the configured interface was inspected based on the direction that the inspect rule was applied.) Now, interfaces are assigned to zones, and inspection policies are applied to traffic moving between the zones. Interzone policies offer considerable flexibility and granularity, so different inspection policies can be applied to multiple host groups connected to the same router interface.
In addition to the zone-based policy firewall model, the Per-Subscriber Firewall on LNS feature introduces the following additional functionality for the Cisco ASR 1000 Series Router:
•
Subscribers can be assigned to a zone in one of two ways:
–
–
•
Stateful inspection and application monitoring occur at the PPP session, enabling the full suite of firewall and broadband features to be applied per subscriber, simultaneously. That is, extra routers or service blades are not required to support the firewall functionality. The firewall functionality is applied by the packet processor engine (PPE) in the forwarding path for broadband traffic.
•
Service providers can track drops on a per-subscriber basis by including the subscriber's username in the drop log messages. These drop log messages can also be sent to an off-box server for additional processing.
•
Service providers can customize the firewall policy for traffic between subscribers in the same zone. Customization is useful for overriding the default behavior, which is the passage of all traffic within the same zone.

BFD IPv6 Encaps Support
The Bidirectional Forwarding Detection for IPv6 (BFDv6) protocol provides fast forwarding path failure detection times for all media types, encapsulations, topologies, and routing protocols. In addition to fast forwarding path failure detection, BFD provides a consistent failure detection method for network administrators. The BFD IPv6 Encaps Support feature updates the Bidirectional Forwarding Protocol (BFD) protocol to provide IPv6 support and accommodate IPv6 addresses.
For information about this feature, see the following document:
http://www.cisco.com/en/US/docs/ios/ipv6/configuration/guide/ip6-bfd.html
BFD—IPv6 Static Route Support
The BFD—IPv6 Static Route Support feature enables BFD for IPv6 to be used to verify next-hop reachability for IPv6 static routes.
For information about this feature, see the following document:
http://www.cisco.com/en/US/docs/ios/ipv6/configuration/guide/ip6-bfd.html
DHCP—DHCPv6 Relay Agent Notification for Prefix Delegation
The DHCP—DHCPv6 Relay Agent Notification for Prefix Delegation feature allows the router working as a DHCPv6 relay agent to find prefix delegation options by reviewing the contents of a DHCPv6 packet that is being relayed by the relay agent to the client.
For information about this feature, see the following document:
http://www.cisco.com/en/US/docs/ios/ipv6/configuration/guide/ip6-dhcp.html
DHCP Relay Server ID Override and Link Selection Option 82 Suboptions
The DHCP Relay Server ID Override and Link Selection Option 82 Suboptions feature enables the relay agent to be part of all DHCP message exchanges by supporting the use of two suboptions of the relay agent information option (option 82). This design allows DHCPv4 to operate in networks where direct communication between the client and server is not possible or desired. When used together, these two suboptions enable the deployment of an architecture where it is desirable to have all DHCP traffic flow through the relay agent, allowing for greater control of DHCP communications.
This feature also introduces the capability to manually configure the interface for the relay agent to use as the source IP address for messages relayed to the DHCP server. This configuration allows the network administrator to specify a stable, hardware-independent IP address (such as a loopback interface).
For information about this feature, see the following document:
http://www.cisco.com/en/US/docs/ios/ipaddr/configuration/guide/iad_dhcpservidlink_mcp.html
DHCPv6 Ethernet Remote ID Option
The DHCPv6 Ethernet Remote ID Option feature adds the remote-ID option to relayed (RELAY-FORWARD) DHCPv6 packets.
For information about this feature, see the following document:
http://www.cisco.com/en/US/docs/ios/ipv6/configuration/guide/ip6-dhcp.html
Integrated Session Border Controller
The Integrated Session Border Controller (SBC) is introduced on the Cisco ASR 1000 Series Routers. The Integrated SBC is integrated with other features on the Cisco ASR 1000 Series Routers, without requiring additional application-specific hardware, such as service blades, or the need to create an overlay network of standalone SBC appliances.
Session border controllers are used as key components in interconnecting Voice over IP (VoIP) and multimedia networks of different enterprise customers and service providers. SBCs are deployed at the edge of networks to meet the need for secure, intelligent border element functions. Using SBCs, the end user can make voice and video calls to another end user without being concerned about protocols, network reachability, or safety of the network.
The SBC enables direct IP-to-IP interconnect between multiple administrative domains for session-based services providing protocol and signaling interworking, security, Quality of Service (QoS), network hiding, statistics gathering, and admission control and management.
Currently the data border element (DBE) functionality of the Integrated Session Border Controller is supported on the Cisco ASR 1000 Series Routers.

http://www.cisco.com/en/US/docs/ios/ipv6/configuration/guide/ip6-stat_routes.html
MQC—Distribution of Remaining Bandwidth Using Ratio
The MQC—Distribution of Remaining Bandwidth Using Ratio feature allows service providers to configure a bandwidth-remaining ratio on subinterfaces and class queues. This ratio specifies the relative weight of a subinterface or queue with respect to other subinterfaces or queues. During congestion, the router uses this bandwidth-remaining ratio to determine the amount of excess bandwidth (unused by priority traffic) to allocate to a class of nonpriority traffic.
For information about this feature, see the following document:
http://www.cisco.com/en/US/docs/ios/qos/configuration/guide/bwdth_remain_ratio.html
PPPoE Session Limit Local Override
The PPPoE Session Limit Local Override feature enables the session limit configured locally on the broadband remote access server (BRAS) or L2TP access concentrator (LAC) to override the per-NAS-port session limit downloaded from the RADIUS server when Subscriber Service Switch (SSS) preauthorization is enabled.

8-Way CEF Load Balancing
Destination IP prefixes are added to the routing table by routing protocols or static routes. Each path is a valid route to reach the destination prefix. The set of active paths is the set of paths with the best cost. Cisco Express Forwarding load balancing is the ability to share the traffic to a destination prefix over up to eight active paths (an increase from the previous support of six active paths). Load among the active paths can be distributed per destination.
BGP Reduction in Transient Memory Usage
The BGP Reduction in Transient Memory Usage feature implements a reduction in transient memory usage by BGP when BGP updates are built in Cisco IOS XE Release 2.
CEF Support for IP Routing Between IEEE 802.1 Q VLANs
Cisco Express Forwarding (CEF) is supported on interfaces on which IEEE 802.1Q encapsulation has been enabled at the subinterface level. You no longer have to disable CEF operation on interfaces that are using IEEE 802.1Q encapsulation on VLAN subinterfaces.
Class-Based Quality of Service Management Information Base
The Class-Based Quality of Service Management Information Base (Class-Based QoS MIB) provides read access to class-based QoS configurations. This MIB also provides QoS statistics information based on the Modular QoS CLI, including information regarding class map and policy map parameters.
This Class-Based QoS MIB is actually two MIBs: CISCO-CLASS-BASED-QOS-MIB and CISCO-CLASS-BASED-QOS-CAPABILITY-MIB.
Compression Control
The PPP Compression Control Protocol (CCP) defines a method for negotiating data compression over PPP links. These links can be either leased lines or circuit switched WAN links such as ISDN. PPP CCP allows vendors to support multiple data compression algorithms.
DLR Enhancements: PGM RFC-3208 Compliance
In compliance with RFC 3208, the DLR Enhancements: PGM RFC-3208 Compliance feature adds off-tree designated local repairer (DLR) support and redirecting poll response (POLR) capability for upstream DLRs to the Cisco implementation of Pragmatic General Multicast (PGM).
Frame Relay 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 where 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 without the FRF.1.2 Annex A Support feature, you cannot change the MTU size on the Frame Relay side and place all PVC data into 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 to "Full status continued" messages that are sent to this packet immediately 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 implement agreement [1] 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 where all PVCs can be reported in one packet. A router running the new functionality must be able to interoperate with routers 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 following example indicates where in the report to look for this field (the text is in bold for this example):
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.
Interfaces MIB: SNMP Context Based Access
The Interfaces MIB (IF-MIB) has been modified to support context-aware packet information in Virtual Route Forwarding (VRF) environments. VRF environments require that contexts apply to Virtual Private Networks (VPNs) so that clients can be given selective access to the information stored in the IF-MIB. Clients that belong to a particular VRF can access information about the interface from the IF-MIB that belongs to that VRF only. When a client tries to get information from an interface that is associated with a particular context, the client can see only the information that belongs to that context and cannot see IF-MIB information that is associated with interfaces that are connected to another VRF to which it is not entitled. No commands have been modified or added to support this feature.
The IF-MIB supports all tables that are defined in RFC 2863 and the CISCO-IFEXTENSION-MIB.
ISSU - IGMP Snooping
This ISSU - IGMP Snooping feature adds ISSU support for IGMP Snooping.
NAT—Performance Enhancement - Translation Table Optimization
The NAT - Performance Enhancement - Translation Table Optimization feature provides greater structure for storing translation table entries and an optimized look up in the table for associating table entries to IP connections.
Parse Bookmarks
The Parse Bookmarks feature quickly processes consecutive similar commands, such as access-lists and prefix-lists, up to five times faster. The Parse Bookmarks feature reduces boot time and load time for large configurations with many similar consecutive commands. This feature is an enhancement to the parsing algorithm; therefore no configuration changes are needed.
PPPoE Over Gigabit Ethernet Interface
The PPPoE over Gigabit Ethernet Interface feature enhances PPP over Ethernet (PPPoE) functionality by adding support for PPPoE and PPPoE over IEEE 802.1Q VLANs on Gigabit Ethernet interfaces.
RADIUS Attribute 52 and 53 Gigaword Support
The RADIUS Attribute 52 and Attribute 53 Gigaword Support feature introduces support for Attribute 52 (Acct-Input-Gigawords) and Attribute 53 (Acct-Output-Gigawords) in accordance with RFC 2869. Attribute 52 keeps track of the number of times the Acct-Input-Octets counter has rolled over the 32-bit integer throughout the course of the provided service; attribute 53 keeps track of the number of times the Acct-Output-Octets counter has rolled over the 32-bit integer throughout the delivery of service. Both attributes can be present only in Accounting-Request records where the Acct-Status-Type is set to "Stop" or "Interim-Update." These attributes can be used to keep accurate track of and bill for usage.
