Cisco Etherchannel Health Status

cliffgoniea

Hello all,

I have a pair of 6509s with a single PAgP link between them using two interfaces on each. Each of these links go from one 6509 via an Ethernet to SONET bridge, through a microwave radio system, then to an identical SONET to Ethernet bridge to the other 6509.

The issue I am experiencing is that one of the interface sets keep dropping out of being bundled to becoming stand-alone. What I would like to have NPM do is to notify me when this occurs.

Thanks!

Cliff

There are MIBs for this:  https://supportforums.cisco.com/discussion/10582256/mibs-monitor-etherchannel-and-trunks-snmp

Object	pagpGroupIfIndex
OID	1.3.6.1.4.1.9.9.98.1.1.1.1.8
Type	InterfaceIndexOrZero
Permission	read-only
Status	current
MIB	CISCO-PAGP-MIB ;   -   View Supporting Images
Description	"If pagpGroupIfIndex is 0, then the inteface is not aggregated to an agport, and is unavailable for normal data reception and transmission. If pagpGroupIfIndex equals the interface's own ifIndex, the interface is aggregated to itself, and behaves as a single interface (as if there were no Fast Etherchannel or PAgP). If pagpGroupIfIndex has any other value, then it must contain the ifIndex of an agport, and the interface is aggregated to that agport. The ifType of an agport is propVirtual(53)."

I also thing there are traps that are thrown when a member goes away which you could also alert on.
