CONVERSATIONAL MAC ADDRESS LEARNING MAC
N7K02-RECT-CORE2 %L2FM-4-L2FM_MAC_MOVE: Mac 408d.5c39.0e4c in vlan 100 has moved from 15 to 1įrom nexus RECT i have been able to decipher the foreign port of nexus CPDA which apparently looks like it is flood of some kind.
On the nexus RECT which has the same kickstart version 6.2.(16), but the last reset shows system version 6.2(10), i can see the logs properly. I am unable to identify the port of origin because most probably there is a bug on this version which is 6.2(16). The nexus CPDA is directly connected to this remote branch and as the switch-id of 100, i can see that there is a mac move from a foreign port to the port where the remote branch is connected to. Since the beginning of times i see mac moves on only one of the vlans that goes through this link, and so far i have been unable to figure out why is this happening, the Vlan in question is VID 100. The link that connects this remote branch as no special configuration, is just a L2 link with the spanning-tree disable.
All the remote branches connect to the core network via a VPC, except one remote branch that connects to the core network via a single link, therefore is connected only to one of the core nexus. They are inter-connected with a fabricpath mode port-channel.

I have been troubleshooting a mac move behaviour on my core network, which is made of 2 Nexus 7K with F3 series modules.
