Configuring X-ON/X-OFF Protocol
By default, X-ON/X-OFF protocol is enabled on the console port. To enable and disable the X-ON/X-OFF
protocol on a console port that you are logged into use the
command by entering
session
xon-xoff
followed by either
enable
or
disable
.
For example, to disable X-ON/X-OFF on a console port enter:
-> session xon-xoff disable
Note.
To enable or disable the X-ON/X-OFF protocol on the secondary CMM you must log into the
secondary CMM and then execute the
session xon-xoff
command.
Converting the Console Port to a Modem Port
If you require a modem connection to the switch, you must convert the console port to support modem
connections by installing a hardware jumper on the CMM. To configure the console port to support
modem connections, refer to the steps below.
Anti-Static Warning.
Eliminate any static electricity by grounding yourself properly. Refer to
Using the
Grounding Wrist Strap and Chassis Grounding Lug
in
Chapter 5, “Network Interface (NI) Modules.”
1
Locate the console port jumpers. The jumpers are located on the CMM’s processor board and are
labeled J100 through J102. The factory-default jumper positions (which support a console connection) are
shown in the figure below.
2
Remove each of the jumpers from the J100, J101, and J102 jumper blocks and reinstall them in the
positions shown below. To remove a jumper, pull it straight up and away from the jumper block. To
replace, slide the jumper over both of the specified pins and gently press down until it meets the jumper
block.
