Hello good people...
has anyone encountered CSCtc03951 - IP packets with unicast DSTIP and multicast DMAC dropped when incoming and leaving the same distributed etherchannel? I have customer with a large installed base of MS NLB clusters, the setup is based around VSS and multichassis (i.e., distributed) etherchannels, and I'm seeking for a simple workaround until the vendor C gets the issue fixed. It's reported with PFC3C, downgrade to PFC3B mode is not possible as it would conflict with VSS, and topological workarounds seem being quite complicated - there are multiple VLANS with such clusters and I would have to isolate them to a separate VRF each in order to make the traffic always pass some other interface for server-to-server communications. Any experience shared will be much appreciated Thanks -- Tomas Daniska Senior CSE/BDM Soitron, a.s.
