SmartLink question on how it works

[chuckk281]

Mark had a question on Smartlink for a customer:

*******************

Does anyone know how SmartLink works?

Is it just monitoring carrier detect, or does it test in some way for vLAN ‘operational’?

We have a customer where the physical uplinks do not appear to be disconnecting (according to the switches), but some of the servers are seeing the vNICs go down – and taking the FCoE with it.

SmartLink only monitors VC uplinks state. This is not a per VLAN monitoring.

From the VC interface you can easily identify when SmartLink has been triggered because the FlexNIC would show as “Not Linked/Smart Link” status :
