CDP is OK on all

Show etherchannel show all link (check up OK)

Traffic pass over all the link (except between 4503-1 and 4503-2 normal)

When we unplug 1/1 from 4503-1 : We don't discover the etherchannel 6509-4503

When we delete equipment 4503-1 on Campus : We don't discover the etherchannel 6509-4503

Any ideas are welcome to appears the etherchannel 6509-1 - 4503-1 on campus.

Thank You.

It is hard to say without seeing the debug logs. May be you can try this;

1. Delete the 6509-1 and 4503-1 devices.

2. Enable debug and trace for topo thru debugging options page

3. Select and discover 6509-2 and 4503-2 devices from Topo map.

4. Disable logging thru debugging options page
