ieee8021QBridgeFdbDynamicCount
Module: IEEE8021-Q-BRIDGE-MIB
OID (symbolic): IEEE8021-Q-BRIDGE-MIB::ieee8021QBridgeFdbDynamicCount
OID (numeric): 1.3.111.2.802.1.1.4.1.2.1.1.3
Node type: OBJECT-TYPE
Type: Gauge32
Access: read-only
Description: The current number of dynamic entries in this Filtering Database.
What is ieee8021QBridgeFdbDynamicCount?
Counts the number of dynamically learned MAC address entries currently in the bridge's forwarding table. This tracks active device discovery. An operator monitors this to detect if the bridge is learning too many MACs (possible spoofing or flooding).
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.4.1.2.1.1.3 snmpwalk -v2c -c public <target> IEEE8021-Q-BRIDGE-MIB::ieee8021QBridgeFdbDynamicCount
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.111.2.802.1.1.4.1.2.1.1.3.1 snmpget -v2c -c public <target> IEEE8021-Q-BRIDGE-MIB::ieee8021QBridgeFdbDynamicCount.1
