Monitoring CDP status using SNMP?
Posted on 2001-08-15
I would like to know how to discover CDP neighbor visibility from a switch using snmp. I currently have four Cat 5500 switches ( two on each site). The sites are connected by two 100mbit WAN links. In the event of one link failing, CDP shows the disappearance of the relevant neighbour. As this event is occuring at layer 2, i am having difficulty in discovering when link loss is occuring ( Alarms do occur, but this this is generally due to spanning tree reconvergence). At present i am using HP openview and Sitescope to monitor these switches. Ideally i would like to monitor the CDP status with Sitescope.If someone could also provide the correct OID for this task, that would be great.
