Thanks for all the responses. I forgot to mention that this link is going
via Dense wavelength division multiplexing (DWDM) transmission network. DWDM
transmission equipment is in the same building. I dont think so distance
should be a problem. One doubt.....whether DWDM supports Ethernet? I read
somewhere that it will support ATM and SONET/SDH. There is no mention of

*Sunil *- There is nothing configured except duplex on both sides. If DWDM
supports Ethernet is there  any thing specific to configure under chassis or
GE interface.
