Supported Hardware
These sections describe the hardware supported in Release 12.2ZU:
•Cisco ME 6500 Series Ethernet Switches (ME6524)
•Gigabit Ethernet SFPs
•Fast Ethernet SFPs
Note The PFC3C partitions the hardware FIB table to route IPv4 unicast, IPv4 multicast, MPLS, and IPv6 unicast and multicast traffic in hardware. Traffic for routes that do not have entries in the hardware FIB table are routed by the MSFC in software. The defaults are:
•IPv4 unicast and MPLS—192,000 routes
•IPv4 multicast and IPv6 unicast and multicast—32,000 routes
The size of the global internet routing table plus any local routes might exceed the default partition sizes.
These are the theoretical maximum numbers of routes for the supported protocols (the maximums are not supported simultaneously):
•IPv4 and MPLS—Up to 239,000 routes
•IPv4 multicast and IPv6 unicast and multicast—Up to 119,000 routes
Enter the mls cef maximum-routes command to repartition the hardware FIB table. IPv4 unicast and MPLS require one hardware FIB table entry per route. IPv4 multicast and IPv6 unicast and multicast require two hardware FIB table entries per route. Changing the partition for one protocol makes corresponding changes in the partitions of the other protocols. You must enter the reload command to put configuration changes made with the mls cef maximum-routes command into effect.

•Clear hardware interface counters—See this publication:
http://www.cisco.com/en/US/docs/switches/metro/me6500/software/12.2_18_ZU/command/reference/cr.html
•CNS Interactive CLI—Network management applications can use the Cisco Networking Services (CNS) agents to manage network routers. The CNS agent provides the capability to send commands to a router from a programmable source. The CNS Interactive CLI feature introduces a new XML interface that allows you to send interactive commands to a router, such as commands that generate prompts for user input. A benefit of this feature is that interactive commands can be aborted before they have been fully processed. For example, for commands that generate a significant amount of output, the XML interface can be customized to limit the size of the output or the length of time allowed for the output to accumulate. The capability to use a programmable interface to abort a command before its normal termination (similar to manually aborting a command) can greatly increase the efficiency of diagnostic applications that might use this functionality. The new XML interface also allows for multiple commands to be processed in a single session. The response for each command is packaged together and sent in a single response event.
•Configurable Per VLAN MAC Learning (PVL)—See the mac-address-table learning command in this publication:
http://www.cisco.com/en/US/docs/switches/metro/me6500/software/12.2_18_ZU/command/reference/cr.html

•Hardware switching for ICMP traffic when Cisco IOS reflexive ACLs are configured. (CSCeb20666)
•Hardware-assisted IP-in-IP tunneling and generic routing encapsulation (GRE) tunneling—The PFC3C support the following tunnel commands:
–tunnel destination
–tunnel mode gre
–tunnel mode ipip
–tunnel source
–tunnel ttl
–tunnel tos
Other supported types of tunneling run in software on the MSFC2A.
The tunnel ttl command (default 255) sets the TTL of encapsulated packets.
The tunnel tos command, if present, sets the ToS byte of a packet when it is encapsulated. If the tunnel tos command is not present and QoS is not enabled, the ToS byte of a packet sets the ToS byte of the packet when it is encapsulated. If the tunnel tos command is not present and QoS is enabled, the ToS byte of a packet as modified by PFC QoS sets the ToS byte of the packet when it is encapsulated.
To configure GRE tunneling and IP-in-IP tunneling, see these publications:
http://www.cisco.com/en/US/docs/ios/12_2/interface/configuration/guide/icflogin.html
/en/US/docs/ios/12_2/interface/command/reference/irfshoip.html
To configure the tunnel tos and tunnel ttl commands, see this publication:
http://www.cisco.com/en/US/docs/ios/12_0s/feature/guide/12s_tos.html
Note the following information about tunnels:
–Each hardware-assisted tunnel must have a unique source. Hardware-assisted tunnels cannot share a source even if the destinations are different. Use secondary addresses on loopback interfaces or create multiple loopback interfaces. (CSCdy72539)
–Each tunnel interface uses one internal VLAN.
–Each tunnel interface uses one additional router MAC address entry per router MAC address.
–The PFC3C supports PFC QoS features on tunnel interfaces.
–The MSFC2A supports tunnels configured with egress features on the tunnel interface. Examples of egress features are output Cisco IOS ACLs, NAT and PAT (for inside to outside translation), and encryption.
•Hardware-assisted Multiple-path Unicast Reverse Path Forwarding (Unicast RPF)—See this publication:

•Hardware-assisted NetFlow Aggregation—See this publication:
http://www.cisco.com/en/US/docs/switches/metro/me6500/software/12.2_18_ZU/configuration/guide/nde.html
•Hardware-assisted Network Address Translation (NAT) and Port Address Translation (PAT) for IPv4 unicast and multicast traffic—Note the following information about hardware-assisted NAT:
–The PFC3C does not support NAT or PAT for multicast traffic.
–The PFC3C does not support NAT or PAT configured with a route map that specifies length.
–The PFC3C does not support NAT or PAT configured with a route map that specifies static translations.
–When you configure NAT or PAT and NDE on an interface, the PFC3C sends all traffic in fragmented packets to the MSFC2A to be processed in software. (CSCdz51590)
To configure NAT or PAT, see the "Configuring Network Address Translation" section at this URL:
http://www.cisco.com/en/US/docs/ios/12_2/ip/configuration/guide/1cfipadr.html
For information about configuring NAT or PAT with route maps, see this publication:
http://www.cisco.com/en/US/tech/tk648/tk361/technologies_q_and_a_item09186a00800e523b.shtml
To prevent a significant volume of NAT or PAT traffic from being sent to the MSFC2A, due to either a DoS attack or a misconfiguration, enter the mls rate-limit unicast acl {ingress | egress} command described in this publication:
http://www.cisco.com/en/US/docs/switches/metro/me6500/software/12.2_18_ZU/command/reference/M1.html
(CSCea23296)
•Hardware-assisted policy-based routing (PBR) for route-map sequences that use the match ip address, set ip next-hop, and set ip default next-hop PBR keywords.
To configure PBR, see the "Configuring Policy-Based Routing" section at this URL:
http://www.cisco.com/en/US/docs/ios/12_2/qos/configuration/guide/qcfpbr_ps1835_TSD_Products_Configuration_Guide_Chapter.html
When configuring PBR, follow these guidelines and restrictions:
–The PFC3C provides hardware support for PBR configured on a tunnel interface.
–The PFC3C does not provide hardware support for PBR configured with the set ip next-hop keywords if the next hop is a tunnel interface.
–If the MSFC2A address falls within the range of a PBR ACL, traffic addressed to the MSFC2A is policy routed in hardware instead of being forwarded to the MSFC2A. To prevent policy routing of traffic addressed to the MSFC2A, configure PBR ACLs to deny traffic addressed to the MSFC2A.
–Any options in Cisco IOS ACLs that provide filtering in a PBR route map that would cause flows to be sent to the MSFC2A to be switched in software are ignored. For example, logging is not supported in ACEs in Cisco IOS ACLs that provide filtering in PBR route maps.
–PBR traffic through switching module ports where PBR is configured is routed in software if the switching module resets. (CSCee92191)
