Learn about how to configure circuits in Prisma SD-WAN.
Circuits consist of circuit categories which
are used in policy rules to identify paths allowed for an application. By
default, there are a few pre-defined circuit categories in the system
that you can use when configuring circuits.
When configuring
circuits, use the optimum parameters for the circuit based on the
circuit category. For example, when using metered circuit categories
in circuits, ensure that you minimize metered LTE
usage.
To add and edit an internet circuit perform
the following steps:
To configure an internet circuit, select
Add
Circuits
.
Select a circuit and the internet service provider from
the drop-down to
Edit
.
Add a name and
(optional)
description for the
circuit.
Enter the
LINK DOWN
and
LINK
UP
speed.
For Bandwidth (BW) Configuration, leave the default as
manual.
(Optional)
Enable
BW Monitoring
if
you would like ongoing measurement of link capacity.
BW Monitoring is enabled by default.
(Optional)
Select
Yes
for
QoS
to
enable shaping and queuing of traffic as defined in your application
policy rules.
(Optional)
Select the setting for
Use
for Application Reachability Probes
.
(Optional)
Enable
LQ Monitoring
if
you would like ongoing measurement of link quality, such as latency,
loss, and jitter.
LQM is enabled by default on branch to data center paths.
For Bidirectional Forwarding Detection (BFD) Mode, select
Aggressive
or
Non-aggressive
and
for devices on version 5.4.1 and later set the VPN Keep Alive Failure
Count and VPN Keep Alive timeout Interval.
Aggressive—Choose aggressive for fast failure detection
of links. This mode is the default mode and is recommended by Prisma
SD-WAN.
Non-aggressive—Choose non-aggressive when you want to reduce
the amount of probe traffic, or for links that are subjected to
high loss or poor quality.
Retain the default cost and click
Done
.
By default, the Cost for a circuit is 128; a value lower
than 128 indicates a lower circuit cost, making the circuit a preferred choice.
