ieee8021CnCpDiscardedFrames

Module: IEEE8021-CN-MIB

OID (symbolic): IEEE8021-CN-MIB::ieee8021CnCpDiscardedFrames

OID (numeric): 1.3.111.2.802.1.1.18.1.5.1.10

Node type: OBJECT-TYPE

Type: Counter64

Access: read-only

Description: The number of data frames discarded by the queue controlled by this Congestion Point due to queue congestion.

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 object of the associated interface (if any).

What is ieee8021CnCpDiscardedFrames?

Counts data frames this specific Congestion Point's queue dropped due to congestion; watching this per-CP counter, as opposed to the bridge-wide ieee8021CnGlobalDiscardedFrames, pinpoints exactly which queue is overwhelmed.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.18.1.5.1.10
snmpwalk -v2c -c public <target> IEEE8021-CN-MIB::ieee8021CnCpDiscardedFrames

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.18.1.5.1.10.1
snmpget -v2c -c public <target> IEEE8021-CN-MIB::ieee8021CnCpDiscardedFrames.1
