Memory Recommendations
The memory recommendation tables have been removed from the Cisco IOS Release 12.2S release notes to improve the usability of the release notes documentation. The memory recommendations that were provided by these tables are available through Cisco Feature Navigator.
Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS and Catalyst OS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or by feature set (software image). Under the release section, you can compare Cisco IOS software releases side by side to display both the features unique to each software release and the features that the releases have in common.
Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:

Any Transport over MPLS for PXF
Any Transport over MPLS (AToM) transports Layer 2 packets over a Multiprotocol Label Switching (MPLS) backbone. AToM enables service providers to connect customer sites with existing data link layer (Layer 2) networks, by using a single, integrated, packet-based network infrastructure— a Cisco MPLS network. Instead of separate networks with network management environments, service providers can deliver Layer 2 connections over an MPLS backbone. AToM provides a common framework to encapsulate and transport supported Layer 2 traffic types over an MPLS network core.
The AToM for PXF features introduces AToM in the PXF-processing path for the Cisco 7304 router.
IP and Ethernet interworkings are supported in PXF as part of this feature.
The following AToM transport modes are now supported on line card, port adapter, shared port adapter, and the native Gigabit Ethernet interface on the Cisco 7304 processor:
•
•
•
•
•
The following modes are supported on the PA-A3-OC3 only:

Layer 2 Tunneling Protocol v3 for PXF on the Cisco 7304 NSE-100
L2TPv3 is an Internet Engineering Task Force (IETF) l2tpext working group draft that provides several enhancements to L2TP for the capability to tunnel any Layer 2 payload over L2TP. Specifically, L2TPv3 defines the L2TP protocol for tunneling Layer 2 payloads over an IP core network using Layer 2 Virtual Private Networks (VPNs).
L2TP has two fundamental parts:
•
•
L2TPv3 signaling is responsible for negotiating control plane parameters, session IDs, and cookies; for performing authentication; and for exchanging configuration parameters. L2TPv3 is also used to reliably deliver hello messages and circuit status messages. These messages are critical to support circuit interworking, such as the Local Management Interface (LMI), and to monitor the remote circuit status.
This feature introduces L2TPv3 in the PXF processing path for Cisco 7304 routers using an NSE-100 (this feature is already available for the NPE-G100). Specifically, the following is supported for L2TPv3 in the PXF processing path:

ATM PVC Trap Enhancements for Segment and End AIS/RDI Failures
When an ATM permanent virtual circuit (PVC) cannot be used to transmit data because of a connectivity failure, it may be placed in a down state. To detect a connectivity failure, various types of Operation, Administration, and Maintenance (OAM) cells can be used. The operator can inform the network management system (NMS) about OAM failures using ATM PVC trap notifications. Depending on the PVC trap notification that is enabled, the PVC state can be kept up or can brought down. The various ATM PVC trap notifications supported for different types of PVC connectivity failure detection mechanisms are as follows:
•
•
•
•
•
When connectivity is restored and the PVC is in a down state, it is changed to an up state and data transfer is allowed to occur over the PVC. This restoration of connectivity can be detected using OAM cells, and the following recovery trap notifications can be used to inform the NMS:
•
•
•
•
•
If the traps in these lists were sent for each PVC failure and recovery, they would generate much traffic for the NMS. To reduce this traffic, at most one trap of each type could be generated in each notification interval. However, because there can be multiple PVCs, each of which can have multiple failures and recoveries, the trap may contain multiple PVCs. To reduce the size of the trap packet, successive PVCs that have the same failures or recoveries are expressed by means of ranges.
In the F5 AIS/RDI failure and recovery traps listed above, separate segment and end AIS/RDI traps are not implemented. The ATM PVC Trap Enhancements for Segment and End AIS/RDI Failures feature introduced in Cisco IOS Release 12.2(25)S allows the generation of separate ATM F5 segment and end AIS/RDI failure and recovery trap notifications. This enhancement also adds the ifDescr object to the traps.

Frame Relay FRF.1.2 Annex A Support
The Frame Relay FRF.1.2 Annex A Support feature is also known as Local Management Interface (LMI) segmentation and supports an enhancement to the Frame Relay LMI protocol where LMI full status messages are segmented because MTU constraints or large numbers of permanent virtual circuits (PVCs). This feature is useful when the MTU size cannot be increased but 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 Frame Relay FRF.1.2 Annex A Support feature, users cannot change the MTU size on the Frame Relay side and place all the PVC data into one LMI packet. With the Frame Relay FRF.1.2 Annex A Support functionality, this problem is solved.
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 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 previous "Full status continued" STATUS message and is considered to be an error event and PVC information elements (IEs) will not be processed. The next time the T391 timer expires, the "Full status" STATUS ENQUIRY procedure is reinitiated.
This feature follows the FRF1.2 implement agreement [1] and allows the Cisco IOS software to be compliant with the FRF1.2 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 using the debug frame-relay lmi privileged EXEC command. An extra field, 04, has been added to the display output. The following example indicates where in the report to look for this field (text in bold for purpose of example):
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 0104 53 02 7E 7DThe string segment "active/inactive" in 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.

NAT—dCEF Support
The NAT—dCEF Support feature enhances the overall performance of Route Switch Processors (RSPs) on a Cisco 7500 series by enabling line cards to perform address translation. Without this feature, any distributed Cisco Express Forwarding (dCEF) switched packet that needs address translation must be switched by the Route Switch Controller (RSC), which increases load and reduces system performance and throughput.
Line cards are able to maintain a subset of the RSC's NAT table. This enables the line cards to switch packets and perform express forwarding within and between port adapters. Because embedded address translation cannot occur at the line card level, packets that require payload translation are punted to the next higher level switching mechanism in the RSC.
NAT—Performance Enhancement—CEF Switching Support
The NAT—Performance Enhancement—CEF Switching Support feature enhances router performance by optimizing packet processing. Through Cisco Express Forwarding (CEF), decisions to translate, punt, drop, or forward a packet are made with a single lookup. To improve performance, packets that do not require translation and fragmented packets are not punted to the process level. Those packets that have special flags, such as TCP syn/fin/reset, are processed in the CEF path itself. Any action that is CPU-intensive is performed by a background process or by process-level NAT code.
NAT—Performance Enhancement—Translation Table Optimization
The NAT Translation Table Optimization Performance enhancement provides greater structure for storing translation table entries and an optimized look up in the table for associating table entries to IP connections.
NAT—Performance & Scalability Enhancement—Timer Wheel
The NAT—Performance & Scalability Enhancement—Timer Wheel feature reduces CPU utilization in cases where routers must manage large numbers of Network Address Translation (NAT) entries and it eliminates the performance bottleneck caused by the previous timer tree model. By using a more efficient data structure and a priority queue to sort the timer and eliminate the sorting operation during a timer insertion, the process of inserting and removing a timer is faster, improving the scalability of a router that is running NAT.
NAT—Rate Limiting NAT Translation

Secure SNMP Views
The User Security Model (USM), View-Based Access Control Model (VACM), and Community MIBs (SNMP-USM-MIB, SNMP-VACM-MIB, and SNMP-COMMUNITY-MIB) contain information that can potentially be used to gain access to a router using Simple Network Management Protocol (SNMP). Therefore, the USM, VACM, and Community MIBs are excluded from the default SNMP access view so as not to allow remote access unless it is specifically configured. However, when an SNMP view is created with any parent object identifier (OID) of these MIBs included (for example "internet included"), these MIBs also are included in the view. To increase security, the Secure SNMP Views feature excludes these MIBs from SNMP access views even when parent OIDs are included in the view.
In releases earlier than this release, when you configure SNMP views with parent OIDs that include the USM, VACM, or Community MIBs, you must explicitly exclude them. For example, the following configuration can be used to exclude security-sensitive MIBs from the SNMP view that is named "test":
! - include all MIBs under the parent tree "internet" snmp-server view test internet included
! -- exclude snmpUsmMIB snmp-server view test 1.3.6.1.6.3.15 excluded
! -- exclude snmpVacmMIB snmp-server view test 1.3.6.1.6.3.16 excluded
! -- exclude snmpCommunityMIB snmp-server view test 1.3.6.1.6.3.18 excludedAs of Cisco IOS Release 12.0(26)S, 12.2(25)S, and 12.2(2)T, the USM, VACM, and Community MIBs are excluded from any parent OIDs in a configured view by default. If you wish to include these MIBs in a view, you must now explicitly include them.

PXF Logical Interface Options on the Cisco 7304 Router Using an NSE-100
On the Cisco 7304 router using an NSE-100, the PXF processing path is enhanced in Cisco IOS Release 12.2(20)S5 to support up to 63 classes per QoS policy (previous IOS releases supported up to 23 classes per QoS policy).
The pxf max-logical-interfaces command is introduced as part of this feature. This command allows you to choose the number of PXF logical interfaces that you want to support on the router. There is a direct trade off between the number of supported PXF logical interfaces on the router and the number of supported QoS traffic classes per policy in PXF. You can configure the pxf max-logical-interfaces command by using either the 4k or 16k options. If the router is configured to support 4,096 PXF logical interfaces (with the pxf max-logical-interfaces 4k command), up to 63 QoS classes per policy can be supported in PXF. If the router is configured to support 16,384 logical interfaces (which is the default setting, or which can be restored by entering the pxf max-logical-interfaces 16k command), up to 23 QoS classes per policy can be supported in PXF.
The show max-logical-interfaces command is also introduced to show the selected number of PXF logical interfaces that is configured in both the running and startup configurations.
For additional information on this feature, see the PXF Logical Interface Options document:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122s/122snwft/release/122s20/pxflio.htm
FPGA Upgrade Prompt Options on the Cisco 7304 Router
In Cisco IOS Release 12.2(20)S5, the [no] upgrade fpga prompt command is introduced. This command enables and disables FPGA prompting when an FPGA incompatibility is detected. FPGA upgrading prompting is still enabled by default. If FPGA prompting is disabled (with the no upgrade fpga prompt command), an FPGA upgrade is automatically performed when an FPGA incompatibility is detected by the router.
For additional information about this command, see the FPGA Bundling and Update document:

Frame Relay Discard Eligibility Bit Marking (PXF Based)
The ability to mark Frame Relay Discard Eligibility (DE) bits via the set fr-de command is now available in the Parallel Express Forwarding (PXF) processing path on the Cisco 7304 router.
The DE bit in the address field of a Frame Relay frame is used as a method for prioritizing the discarding of frames in congested Frame Relay networks. The Frame Relay DE bit has only two settings, 0 or 1. If congestion occurs in a Frame Relay network, frames with the DE bit set to 1 are discarded before frames with the DE bit set to 0. Therefore, important traffic should have the DE bit set to 0, and less important traffic should be forwarded with the DE bit set to 1.
The default DE bit setting is 0. The Class-Based Packet Marking feature allows users to change the DE bit setting to 1 for various traffic, giving users the option of keeping the default value of 0 or changing the value to 1. Users can therefore use Frame Relay DE bit marking to prioritize frames in a Frame Relay network.
For additional information on this and other PXF features, see the "PXF Features" section in the Cisco 7304 Troubleshooting and Configuration Notes document at the following location:
/en/US/docs/routers/7300/troubleshooting/7304_troubleshooting_guides/1270note.html#65935
For general, non-PXF specific information on this feature, see the Class-Based Marking document at the following location:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121newft/121t/121t5/cbpmark2.htm
Generic Routing Encapsulation Tunnel IP Source and Destination VRF Membership (PXF Based)
The Generic Routing Encapsulation Tunnel IP Source and Destination VRF Membership (PXF Based) feature enables users to specify the Virtual Private Network (VPN) routing/forwarding (VRF) membership of a generic routing encapsulation (GRE) tunnel IP source and destination in the Parallel Express Forwarding (PXF) processing path for the Cisco 7304 router. Before the introduction of this feature, the VRF tunnel interface required the global route to the tunnel destination to remain up. This feature removes this restriction.
For additional information on this and other PXF features, see the "PXF Features" section in the Cisco 7304 Troubleshooting and Configuration Notes document at the following location:
/en/US/docs/routers/7300/troubleshooting/7304_troubleshooting_guides/1270note.html#65935
Hierarchical Aggregate Ingress Policing (PXF Based)
Hierarchical Aggregate Ingress Policing support is now available in the Parallel Express Forwarding (PXF) processing path on the Cisco 7304 router.
Hierarchical Aggregate Ingress Policing enables users to first police the aggregate default traffic and then police (via marking) the traffic that belongs to each nested traffic class.
In a Hierarchical Aggregate Ingress Policing configuration, the child policy map can have up to 23 user-defined classes, and the service policy that contains the child policy can be configured only on the default traffic class.
For additional information on this and other PXF features, see the "PXF Features" section in the Cisco 7304 Troubleshooting and Configuration Notes document at the following location:
/en/US/docs/routers/7300/troubleshooting/7304_troubleshooting_guides/1270note.html#65935
Interface Queueing for Subinterfaces (PXF Based)
The Interface Queueing for Subinterfaces feature is now available in the Parallel Express Forwarding (PXF) processing path for the Cisco 7304 router.
The Port Level Queueing for Subinterfaces feature allows port-level quality of service (QoS) configurations to be applied to 802.1q subinterfaces and data-link connection identifiers (DLCIs). QoS features can still be applied specifically to 802.1q subinterfaces and DLCIs, and the QoS configurations on the 802.1q subinterfaces and DLCIs will always take precedence over the port-level QoS configurations when the 802.1q subinterfaces or DLCI configurations conflict with the port-level QoS configurations.
For additional information on this and other PXF features, see the "PXF Features" section in the Cisco 7304 Troubleshooting and Configuration Notes document at the following location:
/en/US/docs/routers/7300/troubleshooting/7304_troubleshooting_guides/1270note.html#65935
MQC Hierarchical Service-Policy Map Infrastructure (PXF Based)
The MQC Hierarchical Service-Policy Map Infrastructure feature introduces hierarchical service policies that do not require a default class at the parent level in the Parallel Express Forwarding (PXF) processing path on the Cisco 7304 router. A user can now define multiple class queues with multiple classes of traffic feeding into each class queue.
For additional information on this and other PXF features, see the "PXF Features" section in the Cisco 7304 Troubleshooting and Configuration Notes document at the following location:
