7.2 Basic MLS Configuration
7.2.8 Verifying MLS configuration
To verify the MLS configuration for an MLS-RP, enter the following command in privileged EXEC mode. This command is not applicable for the Catalyst 6000 Series switch with MSFC or MSFC II performing MLS without any additional configuration.

Router#show mls rp

The display resulting from this command is illustrated in the Figure to the left and displays the following information:

  • Whether multilayer switching is globally enabled or disabled
  • The MLS ID for this MLS-RP
  • The MLS IP address for this MLS-RP
  • The MLS flow mask
  • The name of the VTP domain(s) in which the MLS-RP interfaces reside
  • Statistical information for each VTP domain
  • The number of management interfaces defined for the MLS-RP
  • The number of VLANs configured for MLS
  • The ID of each VLAN configured for this MAC address
  • The number of MLS-SEs to which the router or RSM is connected
  • The MAC address of each switch

Each MLSP-RP is identified to the switch by both the MLS ID and MLS IP address of the Route Processor. The MLS ID is the MAC address of the Route Processor. The MLS-RP automatically selects the IP address of one of its interfaces from MLS enabled interfaces, and uses that IP address as its MLS IP address.

The MLS-SE uses the MLS ID as a determining factor for establishing entries in the MLS cache.

This MLS IP address is used in the following situations:

  • By the MLS-RP and the MLS-SE when sending MLS statistics to a data collection application
  • In the included MLS Route Processor list on the switch
