Configuring Loopback on 2-QDD-C Card
From R7.3.1 onwards, 2-QDD-C card supports loopback on the 100 and 400GE controllers.
On applying client side loopbacks, traffic is looped and does not continue in the 2-QDD-C card. QSFP
squelching happens on applying internal loopback.
Note
To configure the loopback on the controllers, use the following commands.
configure
controller controllertype Rack/Slot/Instance/Port/Lanenumber
sec-admin-state maintenance
loopback [ line | internal ]
commit
The following is a sample in which the internal loopback is configured on the 100GE controller.
