asxOutputQueueCellLoss
Module: Fore-Switch-MIB
OID (symbolic): Fore-Switch-MIB::asxOutputQueueCellLoss
OID (numeric): 1.3.6.1.4.1.326.2.2.0.1025
Node type: NOTIFICATION-TYPE
Description: This trap indicates that the output queue for the given priority has overflowed and cells have been dropped.
What is asxOutputQueueCellLoss?
This SNMP trap (notification) is generated when an output queue at a given priority level overflows and begins discarding ATM cells. It signals an immediate congestion event at the egress interface. An operator receives this alert to understand when and where cell loss is occurring on the switch fabric.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' Fore-Switch-MIB::asxOutputQueueCellLoss snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.326.2.2.0.1025
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
Example snmptrapd log entry:
zoo11-linux.zoo [UDP: [192.168.30.111]:63572->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (75333204) 8 days, 17:15:32.04 SNMPv2-MIB::snmpTrapOID.0 = OID: Fore-Switch-MIB::asxOutputQueueCellLoss
