Avaya M770 ATM Switch User’s Guide 49
Disabling a Physical Port
Before any physical port parameters can be changed, cleared, or reset, you must
disable the physical port. To disable a physical port, use the pport
disable command.
Enabling a Physical Port
To enable a physical port, use the pport enable command.
Setting Physical Port Parameters
You can set individual parameters for a physical port. Once a physical port
parameter has been set, ILMI will not override the parameter when the physical
port is re-enabled.
You can set the following parameters for all physical ports:
• payload scrambling
• framing mode
• transmit rate limit
You can set the following parameters only for physical DS3 ports:
• cable length
• mapping mode
• loopback type
• Tx clock source
Note: You must disable the physical port before you can change, clear or reset any
physical port parameters. For more information about how to disable a physical
port, see Disabling a Physical Port on page 49.
To set a parameter for a physical port, you must perform the following steps:
1 Disable the physical port.
2 Set the parameter for the disabled physical port, as required.
3 Enable the physical port.
