[c-nsp] How to bring one link down if another related link goes down

[Geert Nijs]

Hi,

BTW: in which version of Nexus NX-OS has it appeared ? i am looking for that
for some time.

Real world scenario: if your uplink goes down in blade switches, you want
your downstream server interfaces also to go
down to trigger NIC failover to the backup nic (based on link state, with
link state tracking this is quicker than with running hello probes on the
NIC interfaces)

regards,
Geert
