Verifying Bridging
Configuration
Use the following procedure to verify the bridging configuration of the
ATM Backbone SwitchModule:
1
Use the following command to display information about the LEC
bridging configuration.
CB5000> show bridge_port <slot.lec>
verbose
Verify that the bridge port is set to a valid vbridge (1 through 240).
If the bridge port is not set to a valid vbridge, use the following
command to reset it to the correct vbridge:
CB5000> set bridge_port <slot.lec>
vbridge <vbridgenumber>
2
Use the following command to display information about the vbridge
configuration:
CB5000> show bridge_port <slot.bridgeport>
Verify that the vbridge is assigned to the correct Ethernet or FDDI
SwitchModule port.
Verifying Data
Movement
Use the following procedure to determine if there is packet and ATM
cell data movement through the ATM Backbone SwitchModule:
1
Use the following command to display ATM statistics:
CB5000> show atm <slot> statistics
Note the values for the ATM and AAL5 ATM cell counters.
2
Reissue the ATM statistics command and check that the counters have
changed.
3
Use the following command to display bridge port interface statistics:
CB5000> show counter bridge_port <slot.lec> interface
Note the values for the Packet Counters statistic
4
Reissue the bridge port interface command and check that the Packet
Counters statistic has changed.
