New Software Features in Release 12.1(2)E

Note   Release 12.1(2)E on MSFC2 supports configuration of up to 1000 VLAN interfaces.

Local Proxy ARP

The Local Proxy ARP feature allows the MSFC to respond to ARP requests for IP addresses within a subnet where normally no routing is required. With the local proxy ARP feature enabled, the MSFC responds to all ARP requests for IP addresses within the subnet and forwards all traffic between hosts in the subnet. Use this feature only on subnets where hosts are intentionally prevented from communicating directly by the configuration on the switch to which they are connected.

The local proxy ARP feature is disabled by default. Use the ip local-proxy-arp interface configuration command to enable the local proxy ARP feature on an interface. Use the no ip local-proxy-arp interface configuration command to disable the feature. ICMP redirects are disabled on interfaces where the local proxy ARP feature is enabled.

WCCP Layer 2 PFC Redirection

The WCCP Layer 2 PFC Redirection feature allows directly connected Cisco Cache Engines to use Layer 2 redirection, which is more efficient than Layer 3 redirection via GRE encapsulation. A directly connected Cache Engine can be configured to negotiate use of the WCCP Layer 2 PFC Redirection feature. The WCCP Layer 2 PFC Redirection feature requires no configuration on the MSFC. The show ip wccp web-cache detail command displays which redirection method is in use for each cache. Observe the following guidelines:

Configure the Cisco IOS Web Cache Communication Protocol (WCCP) as described in the Cisco IOS Configuration Fundamentals Configuration Guide, under "Configuring Web Cache Services Using WCCP", at:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/fun_c/fcprt3/fcd305.htm

Jumbo Frame Feature on MSFC2

With an MSFC2, you can configure the MTU size on VLAN interfaces to support routing of jumbo frames.

The jumbo frame feature supports only a single larger-than-default MTU size on the switch. Configuring a VLAN interface with an MTU size greater than the default automatically configures all other VLAN interfaces that have an MTU size greater than the default to the newly configured size. VLAN interfaces that have not been changed from the default are not affected.

To configure the MTU value, perform this task:
Step Command Purpose

    1. 

Router(config)# interface vlan vlan_ID

Access VLAN interface configuration mode.

    2. 

Router(config-if)# mtu mtu_size

Set the MTU size. Valid values are from 64 to 17952 bytes.

Note—Set the MTU size no larger than 9216, which is the size supported by the supervisor engine.

    3. 

Router# show interface vlan 111

Verify the configuration.

This example shows how to set the MTU size on a VLAN interface and verify the configuration:

Router(config)# interface vlan 111 
Router(config-if)# mtu 9216
Router(config-if)# end
Router# show interface vlan 111
<...Output Truncated...>
MTU 9216 bytes, BW 1000000 Kbit, DLY 10 usec,
<...Output Truncated...>
Router#

Configure support for junbo frames on the supervisor engine as described in the "Configuring Ethernet, Fast Ethernet, and Gigabit Ethernet Switching" chapter of the Catalyst 6000 Family Software Configuration Guide.

New Software Features in Release 12.1(1)E2

None.

New Software Features in Release 12.1(1)E

ARP on STP Topology Change Notification

The ARP on STP Topology Change Notification feature ensures that excessive flooding does not occur when the MSFC receives a topology change notification (TCN) from the supervisor engine. The feature causes the MSFC to send ARP requests for all the ARP entries belonging to the VLAN interface where the TCN is received. When the ARP replies come back, the PFC learns the MAC entries, which were lost as a result of the topology change. Learning the entries immediately following a topology change prevents excessive flooding later.

There is no configuration required on the MSFC. This feature works with supervisor engine software 5.4(2) or later.

Router-Port Group Management Protocol (RGMP)

RGMP constrains multicast traffic that exits through ports to which disinterested multicast routers are connected. To effectively constrain traffic, RGMP must be supported on both the switches and the routers in the network.

Note   CGMP and IGMP snooping constrain multicast traffic that exits through switch ports to which hosts are connected. They do not constrain traffic that exits through ports to which one or more multicast routers are connected.
Restrictions

The following restrictions apply to RGMP on the MSFC:

  RGMP supports PIM sparse-mode only. RGMP does not support PIM dense-mode. RGMP explicitly supports the two AutoRP groups in dense-mode by not restricting traffic to those groups but by flooding it to all router ports. For this reason, you should configure PIM sparse-dense-mode. If you configure groups other than the AutoRP groups for dense-mode, their traffic will not be correctly forwarded through router ports that have been enabled for RGMP.
Configuration Tasks

Refer to the Catalyst 6000 Software Configuration Guide for guidelines on how to configure RGMP on the Catalyst 6000 family switches:
http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/sw_5_4/index.htm

Step 1   Establish an appropriate topology on the VLANs where you want to use RGMP.

Step 2   Enable RGMP on the switch:

Switch> (enable) set igmp enable
Switch> (enable) set rgmp enable

The first command enables IGMP snooping, the second enables RGMP. Enabling these features on the switch is a global configuration. RGMP has no effect in those VLANs where there is not at least a single router also configured for RGMP.

Step 3   Enable RGMP on each interface that has a topology appropriate for RGMP:

router(config)# vlan-interface 10
router(config-if)# ip rgmp

Step 4   Monitor RGMP on the switch:

Switch> (enable) show  rgmp group [<mac_addr>] [<vlan_id>]
Switch> (enable) show  rgmp group count [<vlan_id>]
Switch> (enable) show  rgmp statistics [<vlan>]
Switch> (enable) clear rgmp statistics
Switch> (enable) show  multicast router [igmp|rgmp] [<mod>/<port>] [<vlan_id>]
Switch> (enable> show  multicast protocol status

Step 5   Monitor RGMP on the MSFC:

router(enable)# debug ip rgmp [<name-or-group_address>]

Limitations and Restrictions

MSFC Limitations and Restrictions

  The above command sets the IPX cache inactivity-timeout to 1 minute and the maximum invalidations per minute to 100.
  HSRP addresses only first hop redundancy; it ensures that the default gateway configured on the clients (workstations) remains up even if one router from the HSRP group goes down.
  HSRP ensures that traffic going from the client through the default gateway to the ultimate destination is supported with the loss of one MSFC.
  The HSRP MAC and IP addresses are never known to the other routers, which means that the reverse traffic from the destination to the originating client may or may not go through the same router. This is especially true if the source and destination are more than one hop away. The second hop router (from the client) will see that the client is reachable through both the MSFCs and through load balancing, and could spread the reverse traffic between the two MSFCs.
  When one MSFC fails, the HSRP detects it fairly fast (10 seconds based on default HSRP settings), which means that traffic from the client to its destination goes through. However, the second hop router has to rely on the routing protocol's (RIP/OSPF) convergence time (from 30 to 90 seconds) to realize that one MSFC is down and will try to send the reverse traffic to the failed MSFC.
  The reverse traffic can flow through either MSFC if the source and destination are more than one hop away.
  By making the ACL used for NAT more specific, you can limit the software-handled packets to only those requiring NAT translation.
  For example, if you use a general ACL (such as permit ip any any) to specify the traffic that requires NAT, then all traffic inbound or outbound on the NAT outside interface will be software routed (including traffic not originating or destined to NAT inside interfaces). If it is possible to use a more specific ACL (such as permit ip 10.1.1.0 0.0.0.255 any), then only the NAT outside traffic matching that ACL will be software routed. This traffic will still be software routed regardless of whether it is originating or destined to NAT inside interfaces. By making the ACL more specific, you can limit the amount of traffic that is software routed due to the NAT ACL.
  If the ACLs on an interface with high priority do not fit in the TCAM, the ACLs for interfaces of lower priority will not be inserted into the TCAM until it is possible to fit the high-priority ACLs into the TCAM.
  Refer to the Catalyst 6000 Family Multilayer Switch Feature Card and Policy Feature Card Configuration Guide for detailed information.
  where tftp_interface is the interface the TFTP boot server is on.
  When a delivery acknowledgment timeout occurs for opcode 118 (i.e. multicast MLS SCP messages), then the impact depends on whether MMLS is in IDLE or ACTIVE state (can be determined by entering the show mls ip multicast statistics command). If MMLS is ACTIVE, the message is only a warning and can be ignored. If MMLS is IDLE, this message displays:
    Multicast MLS is disabled due to internal messaging error
  The feature is disabled on the MSFC. You must disable and reenable the IGMP feature on the NMP before reenabling MMLS on the MSFC.

FlexWAN Module Limitations and Restrictions

Caveats

Open MSFC Caveats - Release 12.1(2)E

  The MSFC does not send a global purge request to the supervisor engine NMP the first time you enter the no ip routing command on the MSFC after a reload. IP traffic continues to be switched by the NMP even after the MSFC is configured with no ip routing.
  Workaround: Issuing the ip routing command followed by the no ip routing command a second time sends a global purge message to the NMP which purges shortcuts on the supervisor engine NMP. (CSCdm91663)
