Configuring Enterprise Edge Services 221P0911588 Issue 01 Enterprise Edge 2.0 Programming Operations GuideQoS Restrictions and DefaultsEnterprise Edge QoS includes the following restrictions and defaults:• By default, the general bulk of traffic (not defined by priority filters) is routedto best-effort Queue 5 (with Queue 1 the highest priority and Queue 8 thelowest). An administrator can define four classes of traffic above the generictraffic and three classes below it.• A maximum of 31 priority filters for best-effort traffic can be created.• The QoS module can be Enabled or Disabled. The default setting is Enabled.• The predetermined WAN bandwidth is always available to VoIP gatewaychannels. That is, VoIP gateway calls are always admitted. The remainingWAN premium bandwidth can be used by other H.323 streams, such asMicrosoft NetMeeting. If there is no VoIP gateway traffic, the VoIP WANbandwidth can be used only by best-effort traffic, not other premium traffic (forexample, NetMeeting). Enterprise Edge does not support preemption ofadmitted premium streams.• Currently, packet prioritizing and priority filters apply only to outbound trafficfor specified interfaces. Inbound traffic is treated on a first in/first out (FIFO)priority.• The maximum port numbers you can reserve for premium traffic is 256.To configure QoS services settings:1.
