delay-restore
Configures a time interval to delay VLT ports bring up after reload or peer-link restoration between the VLT peer switches.
Syntax
delay-restore seconds
Parameters seconds — Enter a delay time, in seconds, to delay bringing up VLT ports after the VLTi device is
reloaded, from 1 to 1200.
Default 90 seconds
Command Mode VLT-DOMAIN
Usage
Information
Use this command to delay the system from bringing up the VLT port for a brief period to allow L3 routing
protocols to converge. If the peer VLT device was up at the time the VLTi link failed, use this command
after you reload a VLT device. The no version of this command resets the delay time to the default value.
Example
OS10(conf-vlt-1)# delay-restore 100
Supported
