Description: The UDP Port within a L2TPv3 Session PDU the EQAM uses to map DEPI flows to the EQAM channels associated to this table entry. When the EQAM device does not support UDP port mapping to DEPI flows, this object reports the value 1701 (the default UDP port when M-CMTS Initiates a DEPI session with L2TPv3 header over UDP).
What is docsIfMCmtsEqamDownstreamUdpPortMapping?
Reports the UDP port the EQAM uses inside an L2TPv3 DEPI session to map incoming flows to this specific QAM channel; if the EQAM doesn't support per-flow UDP port mapping it just reports the DEPI default of 1701. An operator checking DEPI connectivity issues can use this to confirm which UDP port a given downstream's traffic is actually arriving on at the edge-QAM.
