hwMacExpire
Module: HUAWEI-ETHERNET-PORT-MIB
OID (symbolic): HUAWEI-ETHERNET-PORT-MIB::hwMacExpire
OID (numeric): 1.3.6.1.4.1.2011.5.14.1.3
Node type: OBJECT-TYPE
Type: TimeTicks
Access: read-write
Description:
What is hwMacExpire?
This object's source DESCRIPTION is blank, but its TimeTicks syntax and name indicate it configures the MAC address table aging time, i.e., how long a learned MAC entry is kept before expiring if no traffic refreshes it. An admin tunes this value to balance forwarding-table churn against how quickly moved or disconnected devices are forgotten. Illustratively, setting it to 30000 (in TimeTicks, hundredths of a second) would apply a roughly 5-minute aging period.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2011.5.14.1.3 snmpwalk -v2c -c public <target> HUAWEI-ETHERNET-PORT-MIB::hwMacExpire
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2011.5.14.1.3.1 snmpget -v2c -c public <target> HUAWEI-ETHERNET-PORT-MIB::hwMacExpire.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.2011.5.14.1.3.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> hwMacExpire.1
