Chapter 7 Managing Module Hardware

Managing the speed for the serial port

To display the current speed for the serial interface port, use the hardware serial speed command.

Command: M15-155s8:/>hardware serial speed

Output: M15-155s8:/>9600

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:

Command:

M15-155s8:/>hardware serial speed [480096001920038400]

Example:

M15-155s8:/>hardware serial speed 9600

Parameters:

[4800960019200384

Select the speed at which the serial interface port will

communicate.

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:.

Command:

M15-155s8:/>hardware

vpivcibits

 

 

 

 

Output:

Configured number

of

vpi bits:

3,

vci

bits:

12

 

Current number of

vpi bits:

3,

vci

bits:

12

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.

Command: M15-155s8:/>hardware vpivcibits <vpibits> <vcibits>

Example: M15-155s8:/>hardware vpivcibits 4 11

Parameters: <vpibit>

The maximum number of VPI bits for all ports on the module

<vcibits>

The maximum number of VCI bits for all ports on the module

The number of bits that can be used varies with each ATM module. See the table below on the allowed parameters..
