What is ipadDlciRxBECNinCIRAlarm?
This OID triggers an alarm when the device receives a Frame Relay packet marked with BECN (Backward Explicit Congestion Notification) while still within the committed information rate. BECN signals that congestion exists downstream, even though this connection hasn't exceeded its bandwidth limit yet. A network operator sees this alarm to detect early congestion warnings and adjust traffic before the link becomes overloaded.
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::ipadDlciRxBECNinCIRAlarm snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.321.100.1.999.0.25007
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
