ISW-218
Cisco IOS IP Switching Command Reference
May 2008
For Cisco 7600 series routers that are configured with a Supervisor Engine 2, the supported syntax for
the show mls cef ip multicast tcam command is show mls cef ip {multicast tcam [prefix [mask]}
[module
num]].
The following keywords are not supported on Cisco 7600 series routers that are configured with a
Supervisor Engine
2:
• detail
• rpf
• vpn
• vrf
The ... indicates that there is additional information.
The vpn keyword is for expert users only and is not documented.
Information in the output of the show mls cef ip command is also displayed in the show mls cef
commands.
The lookup is performed as a “longest prefix match” and displays the TCAM-entry index that applies to
the specified destination IP address.
The information output is in this format: Index, Prefix, Mask, and Adjacency.
