To configure a no-service loopback port on the 7210 SAS

Before you begin

When you configure a port loopback with MAC swap on a 7210 SAS NE, you must configure a no-service port. You can select a physical port or a virtual port. Not all chassis types support virtual no-service ports.

If you select a physical port as a no-service port, the port cannot contain any SAPs.

For virtual no-service ports, the number of available ports and the port names vary depending on the chassis type. Virtual ports are not displayed on the navigation tree.

You cannot select the same no-service port for more than one function.

See the NE documentation for more information.
