swL2PortStUndersizeFrames
Module: SW-LAYER2-PORT-MANAGEMENT-MIB
OID (symbolic): SW-LAYER2-PORT-MANAGEMENT-MIB::swL2PortStUndersizeFrames
OID (numeric): 1.3.6.1.4.1.326.2.20.1.2.2.2.28.2.4.3.1.27
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: This counter is incremented once for every received packet which meets all the following conditions: 1. Packet data length is less than 64 bytes. 2. Packet has valid CRC. 3. Collision event, late collision event and receive error event have not been detected.
What is swL2PortStUndersizeFrames?
Counts received frames under 64 bytes that nonetheless have a valid CRC and no collision or receive error - legitimately-short but undersized frames, distinct from the collision-related fragments counted in swL2PortStFragments.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.326.2.20.1.2.2.2.28.2.4.3.1.27 snmpwalk -v2c -c public <target> SW-LAYER2-PORT-MANAGEMENT-MIB::swL2PortStUndersizeFrames
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.326.2.20.1.2.2.2.28.2.4.3.1.27.1 snmpget -v2c -c public <target> SW-LAYER2-PORT-MANAGEMENT-MIB::swL2PortStUndersizeFrames.1
