NETGEAR 8800 User Manual • Replacement in ACL-Based Traffic Groups on page 374 • Replacement in Non-ACL-Based Traffic Groups on page 374 Replacement in ACL-Based Traffic Groups If you are using ACL-based traffic groups, you can use the replace-dscp action modifier to replace the ingress DSCP value with the DSCP value of the egress QoS profile as listed in Table 46. Note: If you are using ACL-based traffic groups, you must use ACL action modifiers to replace the DSCP. Traffic that meets any ACL match conditions is not subject to non-ACL-based DSCP priority replacement. For all platforms except BlackDiamond 20800 series switches, NETGEAR recommends that you use ACL-based traffic groups when configuring DSCP replacement. BlackDiamond 20800 series switches do not support the replace-dscp action modifier. Replacement in Non-ACL-Based Traffic Groups For non-ACL-based traffic groups, you can enable or disable DSCP replacement on specific ingress ports. When DSCP replacement is enabled, the DSCP value used on egress is determined by either the QoS profile or the 802.1p priority value. Table 46 shows the default mappings of QoS profiles and 802.1p priority values to DSCPs. Table 46.
