For example, to configure port monitoring session 6 on port 2/3 with a data file called “user_port” in the
/flash directory that will not overwrite older packets if the file size is exceeded, enter:

Note. The size and no overwrite options can be entered on the same command line.
Suppressing Port Monitoring File Creation
By default, a file called pmonitor.enc is created in /flash memory when you configure and enable a port
monitoring session. To prevent the file from being created, use the
monitoring session. To prevent the file from being created, use the
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, and no file.

For example, to configure port monitoring session 6 on port 2/3 with no data file created enter:
-> port monitoring 6 source 2/3 no file
Configuring Port Monitoring Direction
By default, port monitoring sessions are bidirectional. To configure the direction of a port mirroring
session between a mirrored port and a mirroring port, use the
session between a mirrored port and a mirroring port, use the
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, and inport, outport, or bidirectional.
the port to be monitored, a slash (/), the port number of the port, and inport, outport, or bidirectional.
For example, to configure port monitoring session 6 on port 2/3 as unidirectional and inward bound, enter:
-> port monitoring 6 source 2/3 inport
To configure port monitoring session 6 on port 2/3 as unidirectional and outward bound, for example,
enter:
enter:
-> port monitoring 6 source 2/3 outport
For example, to restore port monitoring session 6 on port 2/3 to its bidirectional direction, enter:
-> port monitoring 6 source 2/3 bidirectional
