Q-BRIDGE-MIB

Q-BRIDGE-MIB

Functions Overview

Q-BRIDGE-MIB, defined in RFC 2674, describes the VLAN configuration, status of ports in a VLAN, and port-based or VLAN-based traffic statistics. This MIB can query status of a VLAN, information about the static creation of a VLAN, port-based or VLAN-based traffic statistics, and learning restrictions in a VLAN.

The OID of root objects is as follows:

iso(1).org(3).dod(6).internet(1).mgmt(2).mib-2(1).dot1dBridge(17).qBridgeMIB(7).
