Alex ,
"Move" means a mac/vlan in cam table changes its port
index, usually it is caused by :
1/ misconfiguration . The switch to learn the same
mac/vlan from two different ports in turns.
2/ spt loops
Here is how you can get some insight in the problem ;
If i recall correctly ;
on the switch type 'show mls notification'
You will get something like ;
1: (0005f9df-00023380) Noti Chg TA 1d9de OI 180 V 1
OI ===> port index it learns,
take 4 high bits plus 1 = module number
take 6 low bits plus 1 = port number
TA ==> table address in the cam table .
Now in the example ;
OI 180 ===> 000110000000
^^^^^^ + 1 = port number
^^^^ + 1 = module number
This case 7/1 .
To find the mac address that causes the moves do :
'sh looktable < TA-value from above>
This tells you the mac involving the moves and on what
ports it is 'moving' .
Next step is finding what/were this mac is .
