ieee8021BridgeBasePortExternal
Module: IEEE8021-BRIDGE-MIB
OID (symbolic): IEEE8021-BRIDGE-MIB::ieee8021BridgeBasePortExternal
OID (numeric): 1.3.111.2.802.1.1.2.1.1.4.1.9
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-only
Description: A boolean indicating whether the port is external. A value of true(1) means the port is external. A value of false(2) means the port is internal.
What is ieee8021BridgeBasePortExternal?
This object indicates whether a bridge port connects to external networks (true) or only to internal bridge components (false). Operators use this distinction to understand the topology and role of each port in managing traffic across bridge domains. External ports carry traffic between the bridge and other network segments, while internal ports are reserved for internal bridging operations.
