Module: CISCO-LECS-MIB
OID (symbolic): CISCO-LECS-MIB::lecsMacConfigLastUsed
OID (numeric): 1.3.6.1.4.1.9.9.38.1.2.3.1.3
Node type: OBJECT-TYPE
Type: TimeStamp
Access: read-only
Description: The value of sysUpTime when this entry was last used to map a MAC address to an ELAN name. Managers may opt to use this object to garbage collect entries that have not been used for a prolonged period of time.
What is lecsMacConfigLastUsed?
This timestamp records the sysUpTime value the last time this MAC-to-ELAN mapping entry was actually used to resolve a configuration request, and the MIB explicitly suggests using it to garbage-collect stale entries that haven't been used in a long time. An admin cares because MAC-based ELAN mappings tend to accumulate for retired or replaced devices, and this field is the tool for identifying which entries are safe to prune. For example, a mapping entry whose lecsMacConfigLastUsed corresponds to a sysUpTime from many months ago likely belongs to a decommissioned device and can be deleted.
