We have etherman plus circute terminated in our router fastethernet port and we also created subinterface on this and the encapsulation for the subinterface is dot1q and for phisical interface is 802.1q.
The problem is the link is not coming up when i see the interface status it shows interface is up and protocol is down.
I have changed the duples and speed and tried and removed the encapsulation on logical interface also... but link has not come up.
Please help me in this regard and suggest what i have to do ... or i am missing somthing??
