Module: OPCD-SUPPORT-MIB-V2

Node type: NOTIFICATION-TYPE
Description:
SS7 link down
What is ss7LinkDown?
This is a notification trap that is generated when a Signaling System 7 (SS7) communication link is detected as down or non-operational. The trap alerts network monitoring systems to SS7 connectivity failures that could affect call routing or telecom signaling. Operations teams use this alert to quickly respond to SS7 infrastructure failures and reroute signaling traffic.
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> '' OPCD-SUPPORT-MIB-V2::ss7LinkDown snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.30374.3.1.0.22
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
