Usage
Information
All PFC-enabled priority groups can use the shared headroom space. Headroom is the buffer space that
absorbs the incoming packets after the PFC frames reach the sender. After the threshold is reached, PFC
frames generate towards the sender. The packets sent by the sender after the PFC frames generate are
absorbed into the Headroom buffer. The no version of this command returns the value to the default.
