Exinda Network Orchestrator 2 Getting started | 107
Network Object Location
: The location of a network object (internal or external) is determined by the system com-
paring the IP addresses in the network object to those in the local network object.
Service Level Agreements
: A set of Library objects that allow you monitor the availability of specified IP addresses.
VLANs
: A set of Library objects that allow you to separate hosts on their functional attributes rather than their physical
location.
Dynamic Virtual Circuits
: A set of policies that allow you to enforce fair sharing among hosts or to limit the number
of hosts on the circuit.
2.6.4 Best Practices
Here are the best practices when configuring the Exinda Management Center.
Deployment
Regardless of the number of Exinda Appliances you are working with, it is very important to test EMC configuration on a
single appliance before pushing the configuration onto other appliances.
Pull one appliance into the subgroup and push the configuration to the group. To ensure all the configuration and
customizations are working as you expect, log on to the appliance and check the Optimizer Policy Tree.
If there is a problem with the policy, it is easier to back out a single appliance rather than an entire appliance group. After
you confirm the configuration, add the rest of the appliances to the appliance group and then push the configuration to
the group again.
Appliance Group Inheritance
When working with device subgroups, remember to plan for group inheritance. Implement common configuration at
the parent group level because all subgroups can inherit settings from the parent group.
Plan to support a common Optimizer Policy Tree that can also provide distinct network objects or applications per group,
as appliance groups cannot inherit applications and network objects from their parent groups.
Circuit Size
When configuring circuits and bridges, remember that you might need multiple circuits with different sizes to monitor
various circuit types.
For example, if each link has a different Internet speed, you will have to create a different circuit for each link. Use the
Library to create the different circuits for the different links, which are then re-usable when duplicating policy trees with
only minor changes in link speeds.
What to Configure in the EMC vs. the appliance
The following table outlines the configuration items you can only manage in the EMC and the items you can only
update on individual appliances.
NOTE
If you make changes to VLANs or protocols at the group level, you should send CLI commands from within EMC only.
