Conguring a VLT Port Delay Period
To congure a VLT port delay period, use the following commands.
1 Enter VLT-domain conguration mode for a specied VLT domain.
CONFIGURATION mode
vlt domain domain-id
The range of domain IDs from 1 to 1000.
2 Enter an amount of time, in seconds, to delay the restoration of the VLT ports after the system is rebooted.
CONFIGURATION mode
delay-restore delay-restore-time
The range is from 1 to 1200.
The default is 90 seconds.
Reconguring the Default VLT Settings (Optional)
To recongure the default VLT settings, use the following commands.
1 Enter VLT-domain conguration mode for a specied VLT domain.
CONFIGURATION mode
vlt domain domain-id
The range of domain IDs is from 1 to 1000.
2 (Optional) After you congure the VLT domain on each peer switch on both sides of the interconnect trunk, by default, the system
elects a primary and secondary VLT peer device.
VLT DOMAIN CONFIGURATION mode
primary-priority value
To recongure the primary role of VLT peer switches, use the primary-priority command. To congure the primary role on a VLT
peer, enter a lower value than the priority value of the remote peer.
The priority values are from 1 to 65535. The default is 32768.
3 (Optional) When you create a VLT domain on a switch, the system automatically creates a VLT-system MAC address used for internal
system operations.
VLT DOMAIN CONFIGURATION mode
system-mac mac-address mac-address
To explicitly congure the default MAC address for the domain by entering a new MAC address, use the system-mac command. The
format is aaaa.bbbb.cccc.
Also, recongure the same MAC address on the VLT peer switch.
Use this command to minimize the time required for the VLT system to synchronize the default MAC address of the VLT domain on
both peer switches when one peer switch reboots.
4 (Optional) When you create a VLT domain on a switch, the system automatically assigns a unique unit ID (0 or 1) to each peer switch.
