Quality of Service (QoS): Managing Bandwidth More Effectively
QoS Operating Notes and Restrictions
Table 5-12. Maximum QoS Entries.
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 “Mon-
itoring Resources” in the Management and Configuration Guide for your
switch.

*
• 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.
