What's the best way to watch for Trunk Ports going up and down?

Via SNMP or Syslog?

Most switches on this network have two trunk ports uplinking them to core or distribution switches. I want to find the best way to monitor when the redundant trunk port goes down or becomes unavailable.


Re: What's the best way -

You can use either or. For redundancy, you may use both :)

It all depends on the NMS you plan to use.

Re: What's the best way -

I agree that it is relative to the NMS or Syslog collector you plan to use.

IMHO, syslog collectors are not as flexible. In my case I can just pass the syslog message or the name of the device having the problem. I can only key on a type of message and not the type of interface. Which means that I will see all %LINK-3-UPDOWN: for example. Getting more out of it means getting comfortable with PERL scripting:o)

With an SNMP manager you can use the power of the MIB and key on specific OID's. They also tend to be more flexible with the amount and type of information passed in the alert.

Is there a specific OID for trunk port up/down messages?
