dot1qTpVlanPortInDiscards
Module: Q-BRIDGE-MIB
OID (symbolic): Q-BRIDGE-MIB::dot1qTpVlanPortInDiscards
OID (numeric): 1.3.6.1.2.1.17.7.1.4.6.1.3
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of valid frames received by this port from its segment that were classified as belonging to this VLAN and that were discarded due to VLAN-related reasons. Specifically, the IEEE 802.1Q counters for Discard Inbound and Discard on Ingress Filtering.
What is dot1qTpVlanPortInDiscards?
This counter measures how many received frames on a port were discarded specifically because of VLAN-related rules or filtering. Network engineers check this to spot configuration problems like overly strict filtering or mismatched VLAN settings. High discard counts indicate traffic being blocked that should be allowed through.
