Parameter  Description 
Max Users 
Enter the maximum amount of users allowed here. This value must be between 1 
and 1000. By default, this option is 1000. 
Deny MAC-Move 
Select to enable or disable the deny MAC-move feature here. This option controls 
whether to allow authenticated hosts to do roaming across different Switch ports 
and only controls whether a host, which is authenticated at a port set to the multi-
authenticate mode, is allowed to move to another port. 
If a station is allowed to move, there are two situations. It may either need to be 
re-authenticated or directly moved to the new port without re-authentication based 
on the following rule. If the new port has the same authentication configuration as 
the original port, then re-authentication is not needed. The host will inherit the 
same authorization attributes with new port. The authenticated host can do 
roaming from port 1 to port 2, and inherit the authorization attributes without re-
authentication. If the new port has the different authentication configuration as the 
original port, then re-authentication is needed. The authenticated host on port 1 
can move and re-authenticated by port 2. If the new port has no authentication 
method enabled, then the station is directly moved to the new port. The session 
with the original port is removed. The authenticated host on port 1 can be moved 
to port 2. 
If this feature is disabled and an authenticated host moves to another port, then 
this is treated as a violation error.
