Node type: OBJECT-TYPE

Type: Integer32

Access: read-write

Description: This attribute defines, in seconds, the aging time for non-accessed entries in the Bridge mapping table. The default shall be 300secs. If this set to 0, then aging is disabled.

What is hcxEtherAgeTime?

This read-write Integer32, in seconds and defaulting to 300, sets how long an unused entry stays in the Ethernet card's bridge MAC-address mapping table before being aged out, with a value of 0 disabling aging entirely. It lets an administrator tune how quickly the bridge forgets inactive subscriber devices, trading memory usage against table freshness. For example, an operator seeing the bridge table fill with stale entries from disconnected ComPorts might shorten this value to reclaim table space faster.

Examples
