lists the hardware combinations and scale numbers for authenticated and walk-by users.
Walk-by users: A maximum of three traffic classes on the default session.
Authenticated users: A maximum of three traffic classes per user, with accounting on each traffic

the system operates at the maximum scale before the switchover, the system might exceed the resource limit. Therefore, it
is advisable to run a redundant system at a reduced scale.
