Description: port Id of downstream or upstream channel

What is cadMacChlPortId?

This read-only object identifies the physical port number associated with either a downstream or upstream cable channel on a CMTS (Cable Modem Termination System). Network engineers use this information to map logical channel assignments to physical ports for troubleshooting and management of cable network infrastructure. The identifier is critical for understanding the channel-to-port topology of DOCSIS cable systems.

Examples
