Diagnosing Switch Problems Port Monitoring

OmniSwitch 6800/6850/9000 Network Configuration Guide June 2006 page 29-23

Pausing a Port Monitoring Session

To pause a port monitoring session, use the port monitoring command by entering port monitoring,

followed by the port monitoring session ID and pause. For example, to pause port monitoring session 6,

enter:

-> port monitoring 6 pause

To resume a paused port monitoring session, use the port monitoring command by entering port

monitoring, followed by the port monitoring session ID and resume. For example, to resume port moni-

toring session 6, enter:

-> port monitoring 6 resume

Configuring Port Monitoring Session Persistence

By default, a port monitoring session will never be disabled. To modify the length of time before a port

monitoring session is disabled from 0 (the default, where the session is permanent) to 2147483647

seconds, use the port monitoring source CLI command by entering port monitoring, followed by the

user-specified session ID number, source, the slot number of the port to be monitored, a slash (/), the port

number of the port, timeout, and the number of seconds before it is disabled.

For example, to configure port monitoring session 6 on port 2/3 that will last 12000 seconds before it is

disabled, enter:

-> port monitoring 6 source 2/3 timeout 12000

Configuring a Port Monitoring Data File

By default, a file called pmonitor.enc is created in the /flash directory when you configure and enable a

port monitoring session. This file can be FTPed for later analysis. To configure a user-specified file, use

the port monitoring source CLI command by entering port monitoring, followed by the user-specified

session ID number, source, the slot number of the port to be monitored, a slash (/), the port number of the

port, file, and the name of the file.

For example, to configure port monitoring session 6 on port 2/3 with a data file called “user_port” in the

/flash directory, enter:

-> port monitoring 6 source 2/3 file /flash/user_port

Optionally, you can also configure the size of the file and/or you can configure the data file so that more-

recent packets will not overwrite older packets in the data file if the file size is exceeded.

To create a file and configure its size, use the port monitoring source CLI command by entering port

monitoring, followed by the user-specified session ID number, source, the slot number of the port to be

monitored, a slash (/), the port number of the port, file, the name of the file, size, and the size of the file in

16K byte increments. (The maximum size is 140K bytes.)

For example, to configure port monitoring session 6 on port 2/3 with a data file called “user_port” in the

/flash directory with a size of 49152 (3 * 16K), enter:

-> port monitoring 6 source 2/3 file /flash/user_port size 3
