Verifying a VLT Configuration
To monitor the operation or verify the configuration of a VLT domain, enter any of the following show
commands in EXEC mode on the primary and secondary VLT switches:
Show Command Syntax Description
show vlt backup-link Displays information on backup link operation (see Figure 53-364).
show vlt brief Displays general status information about VLT domains currently
configured on the switch (see Figure 53-365).
show vlt detail Displays detailed information about the VLT-domain configuration,
including local and peer port-channel IDs, local VLT switch status,
and number of active VLANs on each port channel (see
Figure 53-366).
show vlt role Displays the VLT peer status, role of the local VLT switch, VLT
system MAC address and system priority, and the MAC address and
priority of the locally-attached VLT device (see Figure 53-367).
show running-config vlt Displays the current configuration of all VLT domains
(Figure 53-368) or a specified group on the switch.
show vlt statistics Displays statistics on VLT operation (see Figure 53-369).
show spanning-tree rstp Displays the RSTP configuration on a VLT peer switch, including the
status of port channels used in the VLT interconnect trunk and to
connect to access devices (see Figure 53-370).
