Retained port assignments
No port assignments are retained if you are performing a platform upgrade
(NAC 1 to NAC 2).
If the number of available ports on the new system is less than the number
of available ports on the old system, only the existing port assignments are
retained. For example, if a 32-port NAC 2 system was upgraded to a
24-port NAC 2 system, the port assignments for the first 24 ports would be
retained from the previous NAC 2 system.
If your upgrade has no hardware platform change and the new number of
ports is equal to or greater than the number of ports on the previous system,
all port assignments are retained.
If you want to change your port assignments after the installation is
complete, you must alter the port assignments through maintenance. Refer
to the NAC 2 System Administration and Maintenance Guide (NTP
553-4011-510), "Maintenance and administration programs: system shut
down" chapter, "Using the maintenance and administration program"
section, "Configure NAC system" subsection for more information.
