User-priority mapping
There are several ways an incoming packet can be mapped into a user-priority. If the neighboring
devices are untrusted or unable to properly set QoS then the interface is considered untrusted and
all traffic must be user-priority mapped using explicit policies or the IEEE 802.1Q default-priority
mapping is used. If an interface is trusted to have QoS set then the CoS header field can be
interpreted.
NOTE
The user priority mapping described in this section applies to both unicast and multicast traffic.
Default user-priority mappings for untrusted interfaces
When Layer 2 QoS trust is set to untrusted then the default is to map all Layer 2 switched traffic to
the port default user priority value of 0 (best effort), unless configured to a different value.
Table 16 presents the Layer 2 QoS untrusted user priority generation table.
NOTE
Non-tagged Ethernet packets are interpreted as incoming CoS 0.
You can override the default user-priority mapping by applying explicit user-priority mappings.
When neighboring devices are trusted and able to properly set QoS then Layer 2 QoS trust can be
set to COS and the IEEE 802.1Q default-priority mapping is applied.

1 port <user priority> (default 0)
2 port <user priority> (default 0)
3 port <user priority> (default 0)
4 port <user priority> (default 0)
5 port <user priority> (default 0)
6 port <user priority> (default 0)
7 port <user priority> (default 0)
