Chapter 7 Managing Module Hardware
98 Avaya M770 ATM Switch User’s Guide
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 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.
The number of bits that can be used varies with each ATM module. See the table
below on the allowed parameters..
Command: M15-155s8:/>hardware serial speed
Output: M15-155s8:/>9600
