Exinda appliances have multiple queueing modes, each with different advantages. Multi-per-VC queueing mode gives each virtual circuit its queue, making sure that each virtual circuit gets the resources to deal with its traffic. This queueing model is also applied to Dynamic Virtual Circuits (DVC), which are virtual circuits that allocate bandwidth to traffic falling into it based on the total number of users that are using it.
On ExOS7.4.2 and older, users may experience an issue where DVC per-user bandwidth limits are not applied or not followed when the DVC is in Multi-per-VC queueing mode.
This issue was caused by a defect, which was resolved in ExOS7.4.3.
Upgrade the firmware to ExOS7.4.3 to resolve this bug.
