Group Last Changed: The value of system uptime since any of the following conditions occurred:

hub cold or warm-started

this instance of group was created (such as, when a device or module was added to the system)

a change in the value of hub operational status

ports were added or removed as members of the group (such as, group admin. enabled or disabled)

any of the counters associated with this hub that have been reset.

Group Partitioned Ports: The total number of partitioned ports in the group.
