Set Time Interval for The 3Com Router system counts interface flow at every time interval and Flow Control Statistics calculates the unit flow as the reference for standby center. Other flow control

methods (including the dialer threshold command) need this parameter.

Perform the following configuration in system view.

Interface Configuration Before configuring an interface, it is necessary to have a clear idea about the Method networking requirement and network diagram. The following operations must be

implemented at least for the interface configuration.

■If the interface is a physical interface, be clear about the connection state, working mode of the physical interface to be selected and related working parameters.

■If the interface is a WAN interface, assign the encapsulated link layer protocol and working parameters that should be abided by for the opposite port connected with this interface.

■Configure network protocol (such as IP) address of this interface.

■Configure the static route that can reach the destination network via this interface, or configure working parameters of the dynamic route protocol on this interface.

■If the interface supports dial-up, please configure working parameters and management to Modem.

■If the interface acts as the main interface or standby interface at the standby center application, please configure related working parameters of the standby center.
