Quality of Service (QoS): Managing Bandwidth More Effectively QoS Operating Notes and Restrictions Table 5-12. Maximum QoS Entries. Switch Switch 6120G/XG and 6120XG Software Version Z.14.XX Maximum QoS Entries of One Type Notes 250* • Each device (IP address) QoS configuration uses two entries. • Each TCP/UDP port QoS configuration uses two entries. • All other classifier configurations use one entry each. • QoS and ACL resources are drawn from one pool of resources. If IDM-ACLs are configured, the resources remaining for QoS are 128 entries.The other entries are assigned to IDM-ACLs, whether consumed or not. • ARP protection, DHCP Snooping, and other internal features can consume additional resources. *Configuring device (IP address), TCP/UDP QoS entries, or other entries reduces this maximum. See the "Notes" column. Attempting to exceed the above limits generates the following message in the CLI: Unable to add this QoS rule. ■ Not Supported: Use of an inbound 802.1p packet priority as a classifier for remapping a packet's outbound priority to different 802.1p priority. For example, where inbound packets carry an 802.1p priority of 1, QoS cannot be configured use this priority as a classifier for changing the outbound priority to 0. ■ Monitoring Shared Resources: The QoS feature shares internal switch resources with several other features. For information on determining the current resource availability and usage, refer to the appendix titled "Monitoring Resources" in the Management and Configuration Guide for your switch. 5-73
