12.1(5c)EX
Support for this command was introduced on the Supervisor Engine 2.
12.1(8a)E
Support for this command on the Supervisor Engine 2 was extended to the 12.1 E release.
Usage Guidelines
This command is supported on systems configured with a Supervisor Engine 2 only.
In systems configured with a Supervisor Engine 2 with a PFC and an MSFC2, hardware Layer 3 switching provides IP unicast and IP multicast Layer 3 switching for a Supervisor Engine 2, a PFC2, an MSFC2, and fabric-enabled switching modules that have a DFC.
In systems configured with a Supervisor Engine 1 with a PFC and an MSFC or an MSFC2, Layer 3 switching with MLS is provided. Refer to the "Configuring IP Unicast Layer 3 Switching on Supervisor Engine 1" and "Configuring IPX Unicast Layer 3 Switching on Supervisor Engine 1" chapters in the Catalyst 6500 Series Switch Cisco IOS Software Configuration Guide for more information.
Hardware Layer 3 switching applies to IP traffic only.
You can enter this command on the supervisor engine and hardware Layer 3 switching module consoles only. Enter the remote login command to session into the supervisor engine and DFC-equipped module to enter the commands.
Examples
This example shows how to display all the hardware Layer 3 switching table entries:

12.1(5c)EX
Support for this command was introduced on the Supervisor Engine 2.
12.1(8a)E
Support for this command on the Supervisor Engine 2 was extended to the 12.1 E release.
Usage Guidelines
This command is supported on systems configured with a Supervisor Engine 2 only.
The module number keyword and argument designate the module and port number. Valid values depend on the chassis and module used. For example, if you have a 48-port 10/100BASE-T Ethernet module installed in a 13-slot chassis, valid values for the module number are from 2 to 13 and valid values for the port number are from 1 to 48.
In systems configured with a Supervisor Engine 2 with a PFC and an MSFC2, hardware Layer 3 switching provides IP unicast and IP multicast Layer 3 switching for a Supervisor Engine 2, a PFC2, an MSFC2, and fabric-enabled switching modules that have a DFC.
In systems configured with a Supervisor Engine 1 with a PFC and an MSFC or an MSFC2, Layer 3 switching with MLS is provided. Refer to the "Configuring IP Unicast Layer 3 Switching on Supervisor Engine 1" and "Configuring IPX Unicast Layer 3 Switching on Supervisor Engine 1" chapters in the Catalyst 6500 Series Switch Cisco IOS Software Configuration Guide for more information.
Hardware Layer 3 switching applies to IP traffic only.
Hardware Layer 3 switching adjacency statistics are updated every 60 seconds.
You can view hardware-switched IP directed broadcasts information by entering the show mls cef adjacency mac-address number detail command. The number argument is the 48-bit hardware address of the next hop.
For each hardware Layer 3 switching FIB entry, hardware Layer 3 switching stores Layer 2 information from the MSFC2 for adjacent nodes in the hardware Layer 3 switching adjacency table. Adjacent nodes are nodes that are directly connected at Layer 2. To forward traffic, hardware Layer 3 switching selects a route from a hardware Layer 3 switching FIB entry, which points to a hardware Layer 3 switching adjacency entry, and uses the Layer 2 header for the adjacent node in the adjacency table entry to rewrite the packet during Layer 3 switching. Hardware Layer 3 switching supports 256,000 adjacency table entries.
Examples
This example shows how to display information for all adjacency nodes:

12.0(7)XE
Support for this command was introduced on Catalyst 6500 series switches.
12.1(11b)E
This command was changed to include the ge-wan, atm, and pos keywords.
Usage Guidelines
The interface-number argument designates the module and port number. Valid values for interface-number depend on the specified interface type and the chassis and module used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module installed in a 13-slot chassis, valid values for the module number are from 2 to 13 and valid values for the port number are from 1 to 48. This definition also applies to the module number keyword and argument.
If your system is configured with a Supervisor Engine 1, valid values for vlan-id are from 1 to 1005. If your system is configured with a Supervisor Engine 2, valid values for vlan-id are from 1 to 4094. Extended-range VLANs are not supported on systems configured with a Supervisor Engine 1.
When you view the output, note that a colon (:) is used to separate the fields.

show mls ip multicast
To display the MLS IP information, use the show mls ip multicast command.
show mls ip multicast [{complete | partial} [{group {hostname | ip-address} [ip-mask | {interface {interface interface-number}} | {source {hostname | ip-address}}] | {interface {interface interface-number}} | {source {hostname | ip-address} [ip-mask]}]
show mls ip multicast [connected | consistency-check | summary]
show mls ip multicast statistics [group {hostname | ip-address} [source {hostname | ip-address}]]

Usage Guidelines
The interface-number argument designates the module and port number. Valid values for interface-number depend on the specified interface type and the chassis and module used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module installed in a 13-slot chassis, valid values for the module number are from 2 to 13 and valid values for the port number are from 1 to 48.
The number of valid values for port-channel num depends on the software release. For releases prior to Release 12.1(3a)E3, valid values are from 1 to 256; for Releases 12.1(3a)E3, 12.1(3a)E4, and 12.1(4)E1, valid values are from 1 to 64. Release 12.1(5c)EX and later support a maximum of 64 values ranging from 1 to 256. Release 12.1(13)E and later support a maximum of 64 values ranging from 1 to 282; values 257 to 282 are supported on the CSM and FWSM.
If your system is configured with a Supervisor Engine 1, valid values for vlan-id are from 1 to 1005. If your system is configured with a Supervisor Engine 2, valid values for vlan-id are from 1 to 4094. Extended-range VLANs are not supported on systems configured with a Supervisor Engine 1.
When you view the output, note that a colon (:) is used to separate the fields.
For complete shortcuts, the MSFC does not see the packets coming into the RPF interface and replication/forwarding on all the oifs are done by the EARL. For partial shortcuts, the MSFC sees the packet in the incoming VLAN. When a partial shortcut is established, the MSFC does not forward the packet to the interfaces that are getting hardware forwarded.
