[c-nsp] Switchport link-state loss behaviour

[Brett Looney]

Greets,

I have a requirement where I need a switchport (as it happens a trunk port 
on a 3750) to go into an administratively down (or err-disable - I don't 
mind) state when it loses link state. That is, if it regains link state 
again I don't want it to come back up until an administrator modifies the 
port state.

I know I can do this with a SNMP trap and get a management station to 
modify the switchport (via SNMP/telnet/SSH - whatever) but I would really 
like it to happen on the switch itself. Plus, there's always the risk that 
the SNMP trap will go missing and then the port will just come back up on 
its own...

Is there any automagic way to do this?

Thanks!

B.
