What is ipadDLCIRxCongestionExceeded?
This trap notification is sent when the receive congestion threshold on a Frame Relay Data Link Connection Identifier (DLCI) is exceeded, as indicated by reception of BECN or FECN congestion notification flags. The trap alerts operators that the remote end is experiencing congestion and the local device should reduce transmission. Operators use this to implement congestion response policies and monitor WAN health.
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> '' IPADv2-MIB::ipadDLCIRxCongestionExceeded snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.321.100.1.999.0.25005
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
