acdErpVlanFdbFlappingVids0to1023
Module: ACD-ERP-MIB
OID (symbolic): ACD-ERP-MIB::acdErpVlanFdbFlappingVids0to1023
OID (numeric): 1.3.6.1.4.1.22420.2.15.0.4.1.1.14
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: Each octet specifies a set of eight VLANs, the first octet specifying VLAN ID 0 through 7, and so on. Within each octet, the most significant bit represents the lowest numbered VLAN ID. If that bit has a value of '1' then that VLAN is included in the set of VLANs; the VLAN is not included otherwise.
What is acdErpVlanFdbFlappingVids0to1023?
Stores a bitmap identifying which VLAN IDs from 0 to 1023 have detected MAC address flapping on their ports. Network engineers monitor this to detect potential network loops or MAC address spoofing attacks that can destabilize the network. A set bit in the bitmap indicates that VLAN is experiencing repeated MAC address changes requiring investigation.
