e1 | t1 }, which is different from the command of other interfaces.
Exit the Interface View.
In the interface view, input quit to return to the system view.
Set Interface Description The 3Com Router has a configuration item of interface description for router’s
physical interface. Interface description is mainly used to help identifying the
usage of interface. Please use this command in interface view.
Table 81 Set interface description
Set Time Interval for
Flow Control Statistics
The 3Com Router system counts interface flow at every time interval and
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.
Table 82 Set time interval for flow control statistics
The parameter minutes is 5 minutes by default.
Interface Configuration
Method
Before configuring an interface, it is necessary to have a clear idea about the
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.
