OL-1581-08

Chapter 5      Cisco CMTS Debugging Commands

debug packetcable gate

Usage Guidelines

Use this command to enable debugging for the individual PacketCable functional systems on the 
Cisco CMTS. As a general rule, selectively use these commands to debug or troubleshoot problems 
instead of turning on all debugging with the 

debug packetcable all

 command. 

In Cisco IOS Release 12.2(15)BC1 and later, you must also enable debugging for one or more IP 
addresses, using the 

debug packetcable subscriber

 command, before the 

debug packetcable gate

 

command displays any output. The 

debug packetcable gate events process

 command is an exception 

to this, however, because it does not display subscriber-related information. 

Note

The 

debug packetcable all

 command is equivalent to repeatedly giving the 

debug packetcable gate

 

command with each of its possible options. 

Tip

To display detailed debugging output in Cisco IOS Release 12.2(15)BC1 and later releases, use the 

verbose

 option when you enable PacketCable debugging output using the 

debug packetcable 

subscriber

 command. 

Examples

This section shows typical examples for each type of debugging message. 

Commit Event Debugging

The following example shows typical debugging messages for the commit events on a gate. Omit the 

verbose 

option if you do not want to display the header and message contents.
