Description Use the
dialer threshold
command to set the traffic threshold of a single link on
the dialer interface. When the percentage of the traffic on the link to available
bandwidth exceeds the threshold, another link is brought up to call the same
destination address.
Use the undo dialer threshold command to restore the default.
By default, MP flow control is not enabled.
In DCC applications, you may configure load thresholds for links.
If you set a link load threshold in the range 1 to 99, MP tunes allocated bandwidth
according to actual traffic percentage as follows:
■
When the percentage of traffic on a link to bandwidth exceeds the defined
traffic threshold, the system automatically brings up the second link, and
assigns them to one MP bundle. When the percentage of traffic on these two
links to bandwidth exceeds the defined traffic threshold, the system brings up
the third link, and assigns it to the MP bundle, so on and so forth. This ensures
appropriate traffic distribution on DCC links.
■
On the contrary, when the percentage of the traffic on N (which is an integer
greater than 2) links to the bandwidth of N - 1 links decreases under the
defined traffic threshold, the system automatically shuts down a link, so on and
so forth. This ensures the efficient use of DCC links.
If you set the link load threshold to zero, DCC brings up all available links when
triggered by auto-dial or packets instead of looking at traffic size before doing
that. In addition, the
dialer threshold 0 command voids the dialer timer idle
command. DCC does not tear down links that has been established for timeout.
This command must be used in conjunction with the ppp mp command. To
implement MP with DCC, you must use dialer interfaces.
