In the above output, some of the information is in bold which has the following implications:
Port 1813 is used for Event Messaging
There is an open TCP LISTENING socket at port number 2126, which is waiting to accept new COPS connections
There are two ESTABLISHED COPS TCP connections from Call Management Servers to the CMTS at port 2126 – one
connection from 10.1.2.48.45490 and one connection from 10.1.240.82.52639
Port 3918 is used for PCMM Policy Servers. There are two established PCMM Policy Server connections: one from
10.43.200.226.42259 and another from 10.43.200.227.41968.
Enabling and Disabling PacketCable Services
By default, PacketCable services are disabled on the C4/c CMTS. When PacketCable Services are disabled, the C4/c CMTS
disallows any PacketCable signaling connections using the Common Open Policy Service (otherwise known as COPS) from a
Call Management Server (CMS) or Policy Server (PS). As a result, all PC1.x and PCMM requests fail.
To enable PacketCable services on the C4/c CMTS, issue the CLI command:
configure packetcable
PC1.x and PCMM can be enabled independently using the following commands:
configure packetcable dqos no shutdown
configure packetcable pcmm no shutdown
When PacketCable services transition from enabled to disabled, all PacketCable calls in progress are aborted and signaling
links to all C4/c CMTSs are torn down. If PCMM is shut down, all associated PacketCable gates are torn down and all
signaling links to the PSs are torn down.
