IEEE8021-PFC-MIB
The IEEE8021-PFC-MIB enables monitoring and management of Priority-based Flow Control (PFC) states and counters on IEEE 802.1Q-compliant network switches to prevent head-of-line blocking in Data Center Bridging (DCB) environments. It exposes specific metrics including pause frame transmission/reception counts, enabled priority states, and flow control status for individual traffic classes to facilitate congestion control verification.

This allows administrators to verify and manage data center network flow control policies and VLAN membership attributes via SNMP.
The IEEE8021-Q-BRIDGE-MIB enables monitoring and configuration of IEEE 802.1Q VLAN-tagged bridging domains, specifically tracking VLAN membership, port filtering tables, and bridge protocol data unit (BPDU) states on Layer 2 network switches.
SNMP MIB module
The LLDP-V2-MIB module manages IEEE 802.1AB-2009 compliant Link Layer Discovery Protocol agents to monitor local system identity, remote neighbor topology, and per-port transmission statistics, specifically supporting multi-agent architectures where distinct MAC addresses are associated with a single physical port.
The IEEE8021-EVB-MIB provides SNMP management capabilities for Ethernet Virtual Bridging (EVB) devices, specifically monitoring and configuring virtual station interfaces (VSIs), virtual bridge ports, and associated bridge domain parameters as defined in IEEE 802.1Q-2014. It enables the retrieval of operational states, configuration parameters, and performance counters for virtualization features such as MAC-in-MAC encapsulation and port isolation within IEEE 802.1Q-compliant network infrastructure.
The IEEE8021-MSTP-MIB enables the monitoring and configuration of IEEE 802.1Q Multiple Spanning Tree (MSTP) instances, specifically tracking MST region definitions, instance-to-VLAN mappings, and port state transitions across bridged network devices. It provides granular visibility into MSTP topology convergence, including root bridge election status, path costs, and port roles (designated, root, blocked) to ensure loop-free Layer 2 redundancy.
