ieee8021PfcIndications
Module: IEEE8021-PFC-MIB
OID (symbolic): IEEE8021-PFC-MIB::ieee8021PfcIndications
OID (numeric): 1.3.111.2.802.1.1.21.1.1.1.3
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: A count of the received PFC M_CONTROL.indication primitives.
Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime.
What is ieee8021PfcIndications?
This counter tracks how many times this interface has received a PFC pause indication from its link partner, meaning the other end of the link asked this port to stop sending traffic of a certain priority. An admin monitors this to see whether this port's own transmit traffic is frequently being throttled by the device on the other end, indicating congestion beyond this switch. For example, a steadily climbing ieee8021PfcIndications counter tells the admin the link partner keeps pausing this port's transmit traffic, suggesting congestion further along the path.
