Command Reference
dialer threshold
Purpose Use the dialer threshold command to configure the traffic threshold of a link
on the DCC interface so that another link can be enabled to call the same destination
address when the ratio of traffic on all connected links on the DCC interface to the
available bandwidth exceeds the preset percentage.
Use the undo dialer threshold command to restore the default value.
Syntax dialer threshold traffic-percentage [ in | in-out | out ]
undo dialer threshold
Parameters traffic-percentage
Percentage of the actual traffic on the link over the
bandwidth. Valid values are 0 to 99.
in
Only the inbound traffic is calculated.
in-out
Calculates the larger one of the inbound traffic and
the outbound traffic in the actual traffic calculation.
out
Only the outbound traffic is calculated
Default By default, MP flow control is not enabled.
Example Set the traffic threshold on Dialer1 to 80%.

Description If the ratio of the traffic on a link of a DCC interface to the bandwidth exceeds the
defined threshold, the second link is brought up to form an MP bundle with the first
one. When the ratio of traffic on the two links to the bandwidth exceeds the specified
threshold, the third link is brought up, so on and so forth.
On the contrary, when the ratio of the traffic on N (N is an integer greater than or
equal to 2) links to the bandwidth of N-1 links is less than the specified threshold, a
link is dropped. When only one link is left in the MP bundle, whether and when to
disconnect it depends on the timer configured using the
dialer timer idle
command. So far, this command is not available with physical interfaces. It is only
applicable to dialer interfaces and must be used together with the
ppp mp
command.
With traffic-percentage set to 0, the router does not look at the ratio of traffic
to bandwidth when making calls to bring up links. Rather, all the available links come
up automatically. As for links that already exist, they are not torn down because of
