Each row entry represents a fabric card slot in a chassis in
the system. Entries cannot be created and deleted via
SNMP SET operations. When a tmnxChassisEntry is created,
a tmnxFabricEntry is created for each fabric card slot in that
chassis. Before a tmnxChassisEntry can be deleted, each
tmnxFabricEntry for that chassis must be in the proper state
for removal.
