priority trust
Required
By default, the S3100
series switches trust port
priority.
z If you configure to trust
packet priority without
specifying the trusted
priority type, the switch
trusts the 802.1p priority
of the received packets.
z On the S3100-SI series
switches, to configure to
trust DSCP or IP
precedence of packets,
you can use the
priority-trust
command to specify the
trusted priority type
directly, without having
to configure the priority
trust command.
z On the S3100-EI series
switches, to configure to
trust DSCP precedence
of packets, you should
configure the priority
trust command first and
then use the
priority-trust
command to specify the
DSCP precedence.
