Answer 1

Ankit,
You are trying to set speed 1000 on a 10g sfp.
type is 10Gbase-SR
You will need to insert a 1gig sfp and then you will be able to set the speed.
Also, I noticed that you posted first with interface 2/6 and the output you gave me was for 4/6. Are you sure you're in the right interface?
