Optionally, the unit ID can be manually configured as shown in theexamples above to minimize the time required for the VLT system to determine the unit ID assignedto each peer switch when one peer switch reboots.8.3 Environment Three: Verifying VLT ConnectivityVLT connectivity can be checked using the VLT commands listed in Table 11.show commandsCommand Purposeshow vlt brief Displays brief information about the VLT configurationshow vlt detail Displays running configuration for VLT membersshow mac-address-table Displays the MAC address tableOn each switch participating in VLT, perform a show vlt brief, show vlt detail and showmac-address-table.
