This was an IOS bug. I was using 12.1 SUPIV IOS (basic IP) for 4507R. I
just upgraded to '4500 series SUPIV 12.2(31) Enterprise Services' And
bandwidth is showing right.

        First check the "show etherchannel summary" output and make sure
that all the interfaces are actually in the channel. If they are and
you want to statically set it to 6Gbps just issue the "bandwidth"
statement on the port-channel interface accordingly. This may be an IOS
bug because as interfaces are added and removed from the channel the
interface bandwidth is supposed to adjust accordingly. This allows
spanning-tree to calculate the correct cost based on the aggregate
bandwidth of the members in the channel group.

Well, this ether-channel is L2. 'show int po 1' output shows this as 1
gig BW.

What routing protocol are you running?

Dear Group, I do have Ether-channel running between 4507 gig module and
3560 gig switch. I am bundling 6 ports to form the channel. There are
no probs with the channel. But I just noticed the port channel is
showing as 1 gig BW, well it should be 6 gig in my config.

Why does it show 1 gig BW in all show commands, is there any way to see
the real BW of an ether-channel in IOS.
