change carrier-delay Nexus 3064

[santox]

Hi, I have a Nexus 3064 version 6.0(2)U6(7)  where I connected 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

You need to change carrier delay so networkl will co-up with suggestions :

look at the config :  ( nexus 7K, same config works on nexus 3K)

ok man I will try this config.

Provider tells me that I must do the change in phisical port and not in vlan so I dont try this command.

Now I do a test and let u know.

Thank you again and have a nice day

Hi we try but doesnt work

Nexus port send LOS in case of sub 50ms service flaps so this command doest have effect on it.
