Managing the speed for the serial port
To display the current speed for the serial interface port, use the
hardware
serial speed
command.
To set up the speed for the serial interface port, use the
hardware serial speed
command and type the desired speed after the command as shown:
Managing the number of VPI and VCI bits
You can configure the number of VPI and VCI bits that will be used for the VPI and
VCI ranges on all the physical ports for this module. To display and/or change the
VPI/VCI bits for the ATM module, use the
VCI ranges on all the physical ports for this module. To display and/or change the
VPI/VCI bits for the ATM module, use the
hardware vpivcibits
command.
Use the
hardware vpivcibits
command to display the maximum number of
VPI and VCI bits that are used for all ports on the module:.
Use the
hardware vpivcibits <vpibits> <vcibits>
command to change
the maximum number of VPI and VCI bits that will be used for all ports on the
module. It takes effect only after the next reboot.
