Configuring a VLT Port Delay Period
To configure a VLT port delay period, use the following commands.
1. Enter VLT-domain configuration mode for a specified 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.
Reconfiguring the Default VLT Settings (Optional) To reconfigure the default VLT settings, use the following commands.
1. Enter VLT-domain configuration mode for a specified VLT domain.
CONFIGURATION mode
vlt domain domain-id
The range of domain IDs is from 1 to 1000.
2. (Optional) After you configure 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 reconfigure the primary role of VLT peer switches, use the primary-priority command. To
configure 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 configure the default MAC address for the domain by entering a new MAC address, use
the system-mac command. The format is aaaa.bbbb.cccc.
