l2PortDemandAgeLowBound

Module: CTRON-SSR-L2-MIB

OID (symbolic): CTRON-SSR-L2-MIB::l2PortDemandAgeLowBound

OID (numeric): 1.3.6.1.4.1.52.2501.1.2.8.1.5

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: The l2PortDemandAgeLowBound value determines how many MAC entries need to be aged-out. See l2PortDemandAgeHiBound. Default value is 85%. Example: if - L2 table capacity = 10,000 entries - l2PortDemandAgeHiBound = 95% - l2PortDemandAgeLowBound = 85%

When the L2 table reaches 95% capacity (9500 MAC entries), 10% of the entries will be aged-out.

What is l2PortDemandAgeLowBound?

This sets what percentage of entries get aged out once demand aging triggers via l2PortDemandAgeHiBound; for example, with a 95% high bound and an 85% low bound, reaching 9,500 of 10,000 entries ages out 10% of them. Admins tune it to control how aggressively the table is trimmed once it nears capacity.
