UDP 1167
Synopsis
- UDP port 1167 is used by Cisco IP SLA Responder (formerly SAA/RTTMON), a feature on Cisco network devices for active performance measurements.
- Real-world examples include Cisco IOS/IOS-XE routers (e.g., ISR/ASR), Catalyst switches (e.g., 2960-X, 3850, 9300), and some NX-OS platforms when ip sla responder is enabled, which listen/respond on UDP 1167 for IP SLA control and test traffic (e.g., UDP echo/jitter).
- Network monitoring tools that configure and run Cisco IP SLA—such as Cisco Prime Infrastructure and SolarWinds Network Performance Monitor—use devices’ responders on UDP 1167 during tests.
