Checking and Troubleshooting
Checking and Troubleshooting
Use the following procedure as a quick checkout of the tag switching configuration and operation
with respect to the BPX switch.
Step 1 Wait a while, and check whether the controller sees the interfaces correctly;
on the TSC, enter the following command:
tsc# show controllers VSI descriptor
and the an example output is:
Note Check the TSC on-line documentation for the most current information.

Step 2 If there are no interfaces present, first check that card 4 is up,
with, on the BPX switch:
dspcds
and, if the card is not up:
resetcd 4 h
and/or remove the card to get it to reset if necessary.
Note This example assumes that the controller is connected to card 4 on the switch. Substitute a
different card number, as applicable.
