UDP 1161
Synopsis
- UDP 1161 is used by the Broadcom (formerly CA/Concord) SystemEDGE agent for its Health Polling service; CA eHealth and CA Spectrum/DX NetOps managers poll SystemEDGE on this port in production deployments.
- IANA registers UDP 1161 as “health-polling,” matching the CA eHealth/SystemEDGE implementation; its companion traps are on UDP 1162 (“health-trap”).
- Many enterprises expose UDP 1161 on servers running the SystemEDGE agent so their CA/Broadcom monitoring platforms can collect health and performance data.
- In practice, some Net-SNMP deployments listen on UDP 1161 as a non-privileged alternate SNMP port (e.g., inside Linux containers or when run unprivileged), with firewall/NAT forwarding from 161 to 1161.
