I have 3750E with c3750e-universalk9-mz.122-50.SE3 IOS. I have two redundant Links to different ISPs with equal Cost. G0/1 and G0/2, both are advertised in ospf within same area with equal cost. I have snmp enable traps and my snmp is connected in a remote location via these ospf links.
Normally snmp-serve receives these traps via G0/2 link and when G0/2 link fails the snmp-server will receive these traps via g0/1. But in this case snmp-server does not receive the Adj-changes logs OR G0/2 down logs. Logs are generated on local Switch but they are not seen on SNMP-SERVER, so in this case Person Monitoring the snmp-server cannot identify that the link g0/2 is now down or ospf nei is down via g0/2.
help me to resolve this issue.
