Hi, I have a Nexus 3064 where is connect a L2 protected.
When I have a fiber cut, provider switch automatically to backup line withouth problem. When master is going up, they cant switch to the master because flap of Nexus port is <50ms.
They tell me to
"be able to advise how to increase “carrier-delay down” time on your ports in order to not send LOS during protection switch (sub 50ms flaps)."
I try to find something on the internet but I cant.
Someone can help me to try a way to fix this?
have a nice day

Hi marce
I try this command and set to 300msec to my used vlan and doesnt work.
ports send LOS in case of sub 50ms service flaps

- Check current software version being used on the 3064 , use an advisory release if applicable , check if that can help.

Hello @santox ,
you should apply the command to the physical interface not on an SVI or at VLAN level.
Hope to help

Hi,
i find this command that seems to be good for my problem.
I try to use but doesnt work.
i cant believe that I replace my Mikrotik switches with Nexus and now I have this problem with my L2 links.
any ideas?
have a nice day
Debounce time: The port debounce time is the amount of time that an interface waits to notify the supervisor of a link going down. During this time, the interface waits to see if the link comes back up. The wait period is a time when traffic is stopped.

This command is only for SVI with Nexus - Cisco Nexus 7000 Series NX-OS Interfaces Configuration Guide - Configuring Basic Interface Parameters [Cisco Nexus 7000 Series Switches] - Cisco
