diag portloopbacktest

Usage Guidelines During abnormal termination, the system might be in unusable state. Perform reload to reboot the
chassis or switch to recover.
In slot-based systems, the blade under test undergoes a reset or a reinitialization sequence as
part of cleanup.
The rbridge-id is an optional parameter. If the rbridge-id is not specified, the test is assigned to the
local RBridge ID.
CAUTION
This is a disruptive command. You must disable the chassis and switch before running the test. In
addition, you must reload or fastboot the switch or chassis after the test has completed running.
