Cisco nexus 6000 mac moving not working

Hi friends,

I have 6001 Chassis one unit dc switch.

mac move detection is enabled as stated in documentation:

# configure
# mac address-table notification mac-move
# logging level spanning-tree 6
# logging level fwm 6
# logging monitor 6

But id does not work at all.

Looks like it is enabled:

 # show running-config | include move
 mac address-table notification mac-move
 # show logging level 
 Facility        Default Severity        Current Session Severity
 --------        ----------------        ------------------------
 ...
 fwm                     6                       6
 ...
 stp                     3                       6
 ...

When I try to test this out (Simply reconnecting between ports on downstream switches. The vlan is the same, so the mac really flaps between ports on upstream NX-OS switch), notifications are not sended to my logs.

 

And I found that this output is a little bit strange:

# show mac address-table notification mac-move
 MAC Move Notify Triggers: 2814884
   Number of MAC Addresses added: -1214153019 
   Number of MAC Addresses moved: 0 
   Number of MAC Addresses removed: -1214196878 
# show version
...
kickstart: version 7.2(1)N1(1)
system:    version 7.2(1)N1(1)

Re: Cisco nexus 6000 mac moving not working

Thanks, for sharing.

The main problem that I have old cisco 7600 connected to nexus 6000 side by side, with mac-move enabled too.

7600 complains (even spams with messages), when I've reconnected my servers, but nexus not
