Need a flapping interface resource

Hi all,

Has anyone figured out how to make a web resource for flapping objects such as IF up/down? It seems I can make an alert for this but not a web resource.

Thanks - Andy

What exactly is the logic you would want to use to define a flapping interface, should be pretty easy to whip up a report from the event history table of any interface with more than x numer of status changes within y minutes. Or even simpler, if you don't have a particularly noisy environment just list off every interface down or up event for the last 24 hours or so.

We just had an issue this morning where a cable or SFP was beginning to freak out. "Freak out" is a technical term for those non-network types out there. The flap was detected based on syslog messages:

%DUAL-5-NBRCHANGE: EIGRP-IPv4 1: Neighbor xxx.xxx.xxx.xxx (GigabitEthernet0/0/1) is down

%DUAL-5-NBRCHANGE: EIGRP-IPv4 1: Neighbor xxx.xxx.xxx.xxx (GigabitEthernet0/0/1) is up: new adjacency

However, EIGRP is also being monitored by Orion...so that might be another method as well. Or maybe IP SLA or NetPath are options.

Just some random ideas.

Maybe this will assist....
