Quality of Service (QoS): Managing Bandwidth More Effectively
QoS Operating Notes and Restrictions
■ 5300xl and 4200vl Switches—Non-Supported IP Packets: The DSCP
policy codepoint-remarking operation is not supported in any QoS classi-
fier for packets carrying IP options in the packet header.
■ All Switches—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.
