7.4 MLS on the Switch
7.4.4 MLS configuration example
This example illustrates a basic MLS configuration using a Catalyst 5505 Switch with an RSM. Because MLS in enabled by default on the switch, we will focus on the configuration of the RSM.

By looking at the show running-config command on the RSM, it can be seen that three VLANs configured. VLAN 1 is the management VLAN, and we are enabling MLS between VLAN 100 and 200.

Several show commands are listed to verify the MLS configuration. The important output of these commands has been bolded.
