SummaryIt is possible to base an optimizer policy based on the VLAN tag of traffic on the network.
OverviewVLAN tagging is an important concept that allows for traffic to be logically separated into virtual networks. The VLAN tag lets network devices determine where to send traffic and how to route it internally. The Exinda is no exception; it possible to use the VLAN tag in order to prioritize, optimize or otherwise shape traffic. Because the Exinda does deep packet inspection, it can analyze these tags at a packet level, and direct traffic accordingly. To perform this, two things have to be done:
- The VLAN tag must be identified as a VLAN Object
- A policy (or virtual circuit) must be made in the optimizer that will utilize these tags.
Once the VLAN Object is made, the policy is created under Configuration > Optimizer. Under creating (or editing) a policy, the first column under the Filter Rules is 'VLAN', which will show a dropdown list of the VLAN tags that have been created in the Exinda.
By selecting the VLAN tag that is appropriate to the policy that is being created, any traffic that is tagged with that VLAN going through the Exinda will obey the policy. This policy does not to be set up for ALL applications or ALL sources or destinations; it can be further defined by putting a filter on any one of the other fields as well.
