Restrictions for the Cable IPC Statistics Collection Tool
The Cable IPC Statistics Collection tool has the following restrictions:
Information About the Cable IPC Statistics Collection Tool
The Cable IPC Statistics Collection tool monitors IPC messages between cable interface line cards and the RP in a cable communications network. The IPC messages include configuration commands, responses to the configuration commands, and other events that a cable interface line card reports to the RP.
The tool provides the following message statistics:
- Send and receive message counts and byte counts.
- Wait time between request sent and response received for blocked request messages.
- Process time used by the message handler for received request messages.
The tool provides the following queue statistics:
- Queue size.
- Wait time from a message that is enqueued to a message that is dequeued.
- Enqueue and dequeue message counts.
- Queue flush message counts.
Note | To save system memory and keep the normal operation performance, the Cable IPC Statistics Collection tool is disabled by default. You can enable the tool using the cable ipc-stats command in global configuration mode. When you enable the tool, a new database memory buffer is allocated, and the API functions start updating the statistics database. When you disable the tool, the allocated memory is freed. We recommend that you enable this tool only when it is necessary as the tool consumes considerable amount of CPU memory while running on a Cisco CMTS router. The actual memory usage varies based on how many messages are defined in a particular Cisco IOS image. |
How to Enable the Cable IPC Statistics Collection Tool
This section contains the following procedures:
Enabling the Cable IPC Statistics Collection Tool
The cable ipc-stats command is synchronized to all cable interface line cards from the active RP. You do not have to use this command on cable interface line cards separately.
| Command or Action | Purpose |
|---|
Verifying IPC Statistics
To verify IPC statistics, use the show cable ipc-stats command as shown in the following example:
Router# show cable ipc-stats
ubr10k2apatil#show cable ipc-stats

Note | When you run the show cable ipc-stats command, a separate shadow database buffer is allocated, and the contents of the active database are copied to the shadow database to display the IPC statistics. This ensures that all the statistics are frozen at the same time for easy comparison and analysis. To clear the active database, use the clear cable ipc-stats command in privileged EXEC mode. This command resets all the statistics in the active database to zero. |
Configuration Example for the Cable IPC Statistics Collection Tool
The following example shows how to configure the Cable IPC Statistics Collection Tool on a Cisco CMTS router:
Router# configure terminal Router(config)# cable ipc-stats
