I would like to connect an old batm switch to a new cisco catalyst switch with fibre gigabit ethernet but a conenction can not be esablished. I checked the fibre ports on both sides with a pc. They are on both sides (batm + cisco) ok. I figured out that therefore the following configuration setting on the pc ethernet nic is required: FIRST CONFIG: A pc #1 and a pc #2 are connected directly to the gigabit ethernet ports of the cisco catalyst switch. A ping between these divices is possible. SECOND CONFIG: If i now connect pc #1 directly on the gigabit ethernet port of the old batm switch i have to do 2 thinks before the pc is running. First i have to switch the fibre cables TX to RX and the RX to TX and than i must change the gigabit ethernet nic option "Autonegotiation Port A" from the value "On" into "Off". Now the pc is running with a gigabit ethernet connection over the old batm switch. QUESTION: Is there such a configuration option "Autonegotiation Port A - On/Off" on the catalyst too? I alreday checked out the "udld"-commands, but without any positiv result.
