Hi everyboby, It's possible configure a fiber optic port in 100Mbits on 6509 to connect with another switch ( in esample a intel 510T that have a module 100FX fiber optic).
The only command that I found is " speed nonegotiate ", but the state remaning DOWN....
GigabitEthernet1/9 is down, line protocol is down (notconnect) Hardware is C6k 1000Mb 802.3, address is 0017.0e88.9c50 (bia
