Nortel Networks 8100, 1000BASE-XD manual Port Interface

Using the Passport 8100 Modules

To correct this mode mismatch problem:

1.Use the CLI to disable autonegotiation for the suspect port.

Refer to Reference for the Passport 8000 Command Line Interface Switching Operations for the appropriate CLI commands.

2.Use the CLI to set the speed and duplex mode of the port to match the speed/duplex mode of the connected station.

You may have to try several settings before you find the correct speed/duplex mode of the connected station.

If the problem persists, follow these additional steps:

1.Using the CLI, disable the autonegotiation feature at the connected station.

2.Manually set the speed/duplex mode of the connected station to the same speed/duplex mode you have manually set for the Passport 8100 module port.

Note: Nortel Networks recommends that you manually set the Passport 8100 module port to the desired speed/duplex mode when connecting to any of the following Nortel Networks products:

•Nortel Networks 28000 product family

•Nortel Networks 58000 product family

•BayStack™ 302T switch (100 Mb/s port)
