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.
