26.4 QoS Troubleshooting
• trust cos and exp can be used with other trust or Policy Map.
• trust dscp can be used with other trust or Policy Map. This configuration takes effect to IPv4
and IPv6 packets.
• trust exp, trust dscp and trust cos may be configured at the same time, the priority is:
EXP>DSCP>COS.
• If the dynamic VLAN (mac vlan/voice vlan/ip subnet vlan/protocol vlan) is configured, then
the packet COS value equals COS value of the dynamic VLAN.
• Policy map can only be bound to ingress direction, egress is not supported yet.
• At present, it is not recommended to synchronously use policy map on VLAN and VLAN's
port.
