When you enable an interface, the Tag, Priority, and Promote checkboxes and an
•
802.1p Priority Bit pull-down menu appear for that interface.
Tag – Packets transmitted from this port through this VLAN must be tagged with the
VLAN VID. Packets received through this port destined for this VLAN must be tagged
with the VLAN VID by the source. The Tag option is only available on Global type ports.
Priority – Use any 802.1p priority bits in the VLAN header to prioritize packets within
the Gateway's internal queues, according to DiffServ priority mapping rules.
Promote – Write any 802.1p priority bits into the IP-TOS header bit field for received IP
packets on this port destined for this VLAN. Write any IP-TOS priority bits into the
802.1p priority bit field for tagged IP packets transmitted from this port for this VLAN.
All mappings between Ethernet 802.1p and IP-TOS are made according to a pre-defined
QoS mapping policy. The pre-defined mapping can now be set in the CLI. See "Queue
Configuration" on page 231.
802.1p Priority Bit – If you set this field to a value greater than 0, all packets received
on this port with unmarked priority bits (pbits) will be re-marked to this priority. If the
port 802.1p PBit is greater than 0, the VLAN 802.1p PBit setting is ignored.
