Automatic laser shut on Router/Switch port during link(protocol) failure.

How transceiver power of router/switch ports can be automatically shut during any failure on the link?

Hello

May i ask is this for resiliency, meaning do you wish to automatically fail-over from this interface to another active interface when line-protocol failure occurs?

If you so you could have some options depending on your setup to be able to monitor a line protocol failure.:
Object tracking (can be based on line-protocol,route, ipsla monitoring)
Link state tracking ( used for mostly used for server interface resiliency)
Flexlink -  L2 failover ( no need to have stp active between two uplinks)
EEM scripting ( uses a marco script to automatically admin down the port in question)

If you can elaborate on your requirements it is possible one of the above could be applicable for you.

The failure on a physical link is baked into the transcievers so the link will go down, if you want it admin down then you can set the port to err-disable if it flaps to many times or use a EEM script that was suggested above, just depends on what you are trying to acheive

Actually, a customer wants his device(having ALS feature and connected to the Cisco router/switch) to shut its laser. Whenever there is physical or protocol failure on the link between his devices.

He is not looking for resiliency.

Will that shut the laser(admin down) or shut the port(won't send frames but still trans laser).
