Quality of Service (QoS): Managing Bandwidth More Effectively
Preparation for Configuring QoS
Configuring a Policy When There Are Not Enough Rules Available.Attempting to configure a QoS policy on the switch or a VLAN when there are not enough rules available results in the following:
■The policy is not configured.
■The CLI displays a message similar to the following:
Unable to add this QoS rule. Maximum number
Available. When you add a port to an existing,
■The port is added to the VLAN.
■The QoS classifiers configured on the VLAN are not added to the port, which means that the port does not honor the QoS policies configured for the VLAN.
■The switch generates an Event Log message similar to the following:
cos: Vlan 1 QoS not configured on all new ports. Some QoS resources exceeded
Troubleshooting a Shortage of Rule Resources
The lack of available rules is caused by existing QoS configurations consuming the available rules. Do the following to enable configuration of the desired policy:
1.Use the show qos resources command to determine rule and resource usage.
ProCurve(config)# show qos resources
