dot1dSrPortHopCountExceededDiscards
Module: RFC1286-MIB
OID (symbolic): RFC1286-MIB::dot1dSrPortHopCountExceededDiscards
OID (numeric): 1.3.6.1.2.1.17.3.1.1.16
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The number of explorer frames that have been discarded by this port because the Routing Information Field has exceeded the maximum route descriptor length.
What is dot1dSrPortHopCountExceededDiscards?
This counter tracks the number of explorer frames this port has discarded because the Routing Information Field exceeded the maximum allowed route descriptor length. Admins use it to detect explorer frames traversing too many bridge hops, which can happen in large or poorly segmented source-routed topologies. A high count would suggest raising dot1dSrPortHopCount or redesigning the segment topology to shorten explorer paths.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.17.3.1.1.16 snmpwalk -v2c -c public <target> RFC1286-MIB::dot1dSrPortHopCountExceededDiscards
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.17.3.1.1.16.1 snmpget -v2c -c public <target> RFC1286-MIB::dot1dSrPortHopCountExceededDiscards.1
