648 CHAPTER 45: CONFIGURING A STANDBY CENTER
main interface is a physical interface or sub-interface, use the following
commands in system view to enter the view of the interface.
Table 695 Enter the View of the Main Interface
If the main interface is a virtual circuit, it should be treated differently depending
on the type of the virtual circuit. First, specify its logic channel number in the view
of the physical interface to which it is subordinate, then enter the corresponding
logic channel view.
Use the following commands in the logical channel view.
Table 696 Enter the Logic Channel View
Specifying a Standby
Interface and the
Priority Used by the
Main Interface
Any physical interface or logic channel, including a virtual circuit or dialer route,
can work as a standby interface of the main interface.
Use the following commands in the view of the main interface.
Table 697 Specify Standby Interface and Priority Used by the Main Interface
If one main interface has multiple standby interfaces, repeat these operations. In
addition, if the standby interface is a logic channel, the logic channel should be
made to correspond to the actual virtual circuit or dialer route.
Please perform the following tasks in the views of the physical interface to which
the virtual circuit or the dialer route belongs, and specify the corresponding logic
channel number.
