730 CHAPTER 51: CONFIGURING DCC
Configuring the timeout of call setting up
When placing DCC calls to some remote ends, the intervals between originating
the calls and establishing the connections are not the same. To effectively control
the time that should wait for the connection after a call is originated, the user can
configure the wait-carrier timer to specify a duration, after which DCC will
terminate the call if the connection cannot be established.
Perform the following configuration in dial interface (physical or dialer interface)
view.
Table 771 Configure the Timeout of Call Setting Up
By default, the timeout of call setting up is 60 seconds.
Configuring the buffer queue length of the dialer
Before a dialer buffer queue is established, a packet received from the dial
interface will be discarded if the connection is not established yet. However, if a
buffer queue is established on the dial interface, the packet will be held until a
connection is established rather than discarded.
Perform the following configuration in dial interface (physical or dialer interface)
view.
Table 772 Configure the Buffer Queue Length of the Dial Interface
By default, no buffer queues are configured on dial interfaces.
Displaying and
Debugging DCC
After completing the above configuration steps, execute the display command in
all views to display the running of the DCC configuration, and to verify the effect
of the configuration.
Execute debugging command in all views for the debugging.
