delay-restore
Configures a time interval to delay bringing up the VLT ports 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 link is detected, 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 the exchange of
control information, such as, MAC and ARP tables between VLT peers. 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
