Dialer Timer Autodial - HP MSR series Command Reference Manual

Parameters
traffic-percentage: Percentage of actual traffic on the link to bandwidth, in the range of 0 to 99.
in: Considers only incoming traffic in actual load calculation.
in-out: Considers either incoming traffic or outgoing traffic in actual load calculation, whichever is
greater.
out: Considers only outgoing traffic in actual load calculation.
Usage guidelines
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.
In DCC applications, you can configure load thresholds for links.
If you set a link load threshold in the range of 1 to 99, MP tunes allocated bandwidth according to actual
traffic percentage following these guidelines:
• 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 (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. 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 have been
established due to timeout.
This command must be used in conjunction with the ppp mp command. To implement MP with DCC, you
must use dialer interfaces.
Examples
# Set the link traffic threshold on interface Dialer1 to 80%.
<Sysname> system-view
[Sysname] interface dialer 1
[Sysname-Dialer1] dialer threshold 80
