up.
To view the status of all cards and modules, the
Note

administration EXEC mode.
Verifies the spanning tree.
Enter this command for each RP and SCGE card in the
•
system.
The output for each RP and SCGE card should display
•
the following:
In the Switched Interface column, one GE port
–
should be in the forwarding (FWD) state.
Each RP and SCGE card should display the same
–
designated root MAC address.
Verify that the designated root address matches the
•
expected Catalyst switch, as defined by the Catalyst
switch configuration. The root address should be the
switch with the lowest priority number (0).
For more information to configure and verify the
