a3ComSysBridgeAddressThreshold
Module: A3COM-SWITCHING-SYSTEMS-BRIDGE-MIB
OID (symbolic): A3COM-SWITCHING-SYSTEMS-BRIDGE-MIB::a3ComSysBridgeAddressThreshold
OID (numeric): 1.3.6.1.4.1.43.29.4.10.2.1.6
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: A reporting threshold for the total number of addresses known for the bridge identified by this entry. When this threshold is reached, the event a3ComSysBridgeAddressThresholdEvent is generated. The range of valid values for setting this object is between 1 and the corresponding value reported by a3ComSysBridgeAddressTableSize + 1 (Note that this range applies to values issued in set requests. The current value may be outside this range, for example if the corresponding value of a3ComSysBridgeMode is changed). Setting this object to one greater than the address table size disables the generation of a3ComSysBridgeAddressThresholdEvents since the limit will never be reached.
What is a3ComSysBridgeAddressThreshold?
Sets an integer threshold; when the MAC table exceeds this value, an alert event fires. Engineers use this to proactively warn of address table exhaustion before capacity is reached. Setting it to 7000 on an 8000-capacity bridge triggers an alert when 7000 addresses are learned, allowing buffer room.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.43.29.4.10.2.1.6 snmpwalk -v2c -c public <target> A3COM-SWITCHING-SYSTEMS-BRIDGE-MIB::a3ComSysBridgeAddressThreshold
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.43.29.4.10.2.1.6.1 snmpget -v2c -c public <target> A3COM-SWITCHING-SYSTEMS-BRIDGE-MIB::a3ComSysBridgeAddressThreshold.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.43.29.4.10.2.1.6.1 i <value>
