undo ft1 loopback [ local | remote ]
View
T1-F interface view
Parameter
local: Places the interface in local loopback.
remote: Places the interface in remote loopback.
Description
Using the ft1 loopback command, you can configure a T1-F interface in local or
remote loopback. Using the undo ft1 loopback command, you can disable the local
and remote loopbacks on the interface.

cable itself. These functions should be disabled in normal cases. On an interface,
using this command but with different arguments can respectively enable local
loopback and remote loopback, but these two functions cannot be enabled at the
same time.
