I understand that QoS cannot be achieved on a PIX VLAN interface, but only on physical interfaces (at least as far as release 7.2 goes). If that is correct, are there any workarounds that can be implemented ? How about version 8.0 ?
QoS is a traffic-management strategy that allow you to allocate network resources for both mission-critical and normal data, based on the type of network traffic and the priority you assign to that traffic. In short, QoS ensures unimpeded priority traffic and provides the capability of rate-limiting (policing) default traffic.
