IEEE8021-PFC-MIB
AI MIB Summary
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.
Priority-based Flow Control module for IEEE 802.1Q.
