Module: CISCOSB-CDP-MIB
OID (symbolic): CISCOSB-CDP-MIB::rlCdpInterfaceMaxNeighborsExceededInMainCache
OID (numeric): 1.3.6.1.4.1.9.6.1.101.137.19.1.10
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: specifies the number of times a CDP neighbor could not be stored in the main cache.
What is rlCdpInterfaceMaxNeighborsExceededInMainCache?
This read-only Counter32 counts how many times a discovered CDP neighbor could not be stored in the main neighbor cache because it was full. An admin monitors it to detect when an interface (often a shared segment or hub) has more CDP neighbors than the main cache can hold. For example, an admin seeing this counter increase on an uplink port would investigate whether an unexpectedly large number of devices are appearing as CDP neighbors there.
