Spanning-Tree Operation
802.1D Spanning-Tree Protocol (STP)
In this example, ports 2 and 3 have
already been configured as a port
trunk (Trk1), which appears at the end
of the port listing.
All ports (and the trunk) are in their
default STP configuration.
Note: In the actual menu screen, you
must scroll the cursor down the port
list to view the trunk configuration
(ports A2 and A3).
