Hello all, I'm sure someone can help me out with this one....... I have two 4006's and each have RSM's in SLOT 2. I'm seeing some route flapping between my port-channel from the SUP II's point of view. I have those 2/1-2 port-channelled and trunked. Can someone review the output that I have provided and let me know what's going on????
*NOTICE* I have boths module 2/1-2 trunking modes in NONEGOTIATE due to those backplane channels connecting to the RSM's, I wanted to force that trunk and not generate any DTP frames. Can someone help me out ??
This is a known IOS s/w bug. When channeling in ON mode, the ports show the neighbor info using CDP data. The IOS s/w sends out CDP packets on both channel interface and physical interfaces. One of the cat ports sees multiple CDP neighbors and reports "not directly connected to switch."
