Configuring MLS
Caution
The
set mls flow destination-source
command purges all the existing shortcuts in the MLS cache and
affects the number of the active shortcuts on the PFC. Exercise care when using this command.
To set the minimum IP MLS flow mask, perform this task in privileged mode:
This example shows how to set the minimum IP MLS flow mask to destination-source-ip:
Console> (enable)
set mls flow destination-source
Configured IP flow mask is set to destination-source flow.
Console> (enable)
Displaying CAM Entries on the Supervisor Engine
The
show cam
command displays the content-addressable memory (CAM) entries that are associated
with a specific MAC address. If the MAC address belongs to an MSFC, an “R” is appended to the MAC
address.
If you specify a VLAN number, only those CAM entries that correspond to that VLAN number are
displayed. If a VLAN is not specified, the entries for all the VLANs are displayed.
To display the CAM entries, perform this task:
This example shows how to display the CAM entries:
