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

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.
