Hi,

Following is the config output of CIsco 6509E chasis.

> NOLACORE#sh int te1/6/16

> TenGigabitEthernet1/6/16 is up, line protocol is up (connected)

> Hardware is C6k 10000Mb 802.3, address is f866.f220.5027 (bia f866.f220.5027)

From the output , we can see thatthe speed ste is 10G.

But it is forced or autonegotitated? Which parameter gives that information?

Its a fiber line.

sh run interface [interface number] - will show you if speed is hard coded.

It's forced. You can't neogotiate the speed and/or the duplex to anything else. The parameters are the modules you are using. You are using "10Gbase-LRM" then the link will negotiate to 10Gb, Full duplex and nothing less.

Thanks everybody..

That was really helpful.

We are running into interop issue between SPARC 10G XAUI and CISCO 6509,10G base LRM.

So we were suspecting the negotiation, if anything exists like the one in copper channels
