Module: CISCOSB-Tuning
OID (symbolic): CISCOSB-Tuning::rlBrgMacHashChainLen
OID (numeric): 1.3.6.1.4.1.9.6.1.101.29.27
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Current depth of the MAC address hashing Table
What is rlBrgMacHashChainLen?
This read-only INTEGER reports the current depth of the bridge's MAC address hashing table, which affects how many MAC addresses can collide into the same hash bucket before lookup performance degrades. An admin cares because a shallow hash chain length under a very large MAC address table can slow down forwarding lookups. For example, an admin seeing elevated MAC-lookup latency on a switch with a large, busy MAC table would check this current chain depth as a possible contributing factor.
