Usage Guidelines
•
The egress priority assigned to an IP packet received on a trusted port is based on the DSCP value of
the packet unless 802.1p is specified using this command.
•
The default classification priority is not used if there is a matching QoS policy rule that sets the egress
priority value.
•
This command does not affect Layer 2 traffic, which is always classified with 802.1p.
•
In some network situations, some IP traffic may be dropped before any QoS rules can take effect for
the traffic.
