Port Monitoring Diagnosing Switch Problems
page 32-26 OmniSwitch AOS Release 7 Network Configuration Guide June 2013
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 -moni-
toring , followed by the port monitoring session ID and resume . For example, to resume port
monitoring session 6, enter:
-> port-monitoring 6 resume
Configuring Port Monitoring Session Persistence
By default, a port monitoring session is enabled. 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 lasts 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. The port monitoring sniffer file can be viewed using software such as
wireShark or ethereal.
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 does 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.
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
To select the the type of port monitoring information captured, use the port-monitoring source CLI
command by entering port-monitoring , followed by the user-specified session ID number, source , the
