Tag Switching 9-21
Configuration Example
Step 5 On the BXM in slot 4, bring up the ports 4.1, 4.2, and 4.3, as follows:
Note The following example enables ports 4.1, 4.2, and 4.3 in trunk mode with the uptrk command,
they could also all be upped in port mode using the upport command. This is because tag switching
and the VSI make no distinction between a “port” and a “trunk”.
uptrk 4.1
uptrk 4.2
uptrk 4.3
