What is cefPeerStateChangeNotifEnable?
This object enables or disables SNMP traps for changes in a CEF peer entity's operational state, the state tracked by cefPeerOperState. Enabling this lets an admin get near-real-time alerts when a line card's CEF peer relationship goes down, rather than discovering the outage only when polling happens to catch a peerDisabled(1) reading. On a chassis where line cards occasionally reload, an admin would enable this trap so the NMS logs the exact moment a card's CEF peer state flipped, aiding correlation with other card-level events.
