Tag – Packets transmitted from this port through this VLAN must be tagged with the VLAN VID. Packets
received through this por t 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 DiffSer v priority mapping rules. See
“Differentiated Ser vices” on page 92
for more information.
Promote – Write any 802.1p priority bits into the IP-TOS header bit field for received IP packets on this
por t destined for this VLAN. Write any IP-TOS priority bits into the 802.1p priority bit field for tagged IP
packets transmitted from this por t 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 271 . See
also “Differentiated Ser vices” on page 92 for more information.
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 por t 802.1p PBit is greater than 0,
the VLAN 802.1p PBit setting is ignored.
• Select an IP Interface for this VLAN if it is to be routed; otherwise leave the default. These selections
will var y depending on your IP inter faces. For example, if you have set up multiple VCCs, these will
appear in the list as
ip-vcc1, ip-vcc2, and so forth.
