|
| rtr(config)#int fas3/1
| rtr(config-if)#me?
| % Unrecognized command
|
|
| So questions:
|
| Is is so that media-type MII and the MII connectors are no longer
| supported?
|
| Why the router thought that the link was up even though there was no
| RJ45 cable connected to the interface?

What type of FastEthernet is it?  PA-FE-TX?  Something else?

Was it working prior to upgrading?  What version were you running previously?
