Allow Tag/Untag on Ingress
Pkt.
Specify tag or untag.
Ta g indicates that ingress packets already matched to
the VLAN Rule must have a VLAN tag to be further
considered; packets without a VLAN tag will be
dropped.
Untag indicates that ingress packets already matched
to the VLAN Rule cannot have a VLAN tag to be
further considered; packets with a VLAN tag will be
dropped. There can be only one untagged rule. The
DSLAM tries to match to a VLAN rule traffic that has
not matched any other rule type. If the packet is
untagged it will match the one and only allowed VLAN
rule that indicates Untagged. If the packet has a tag
then the DSLAM will try to find a Tagged rule that has
a VLAN range defined with the packet’s VLAN ID. If it
finds one it will use that rule, and then the packet will
be checked for all other criteria. If it does not find a
rule to match the packet VLAN ID the packet is
dropped.
VLAN Specify a VLAN ID range that constitutes a match of
this rule. If you selected Untag, the VLAN field should
specify a single VLAN only if you intend to have a
VLAN tag added to packets; if you do not intend to
have a VLAN tag added to packets, the VLAN field
should be left at the 0 - 0 default.
Add VLAN to Ingress Pkt. Specify whether the VLAN ID should be added to
ingress packets.
Priority Specify the priority to be used when adding a
configured VLAN ID to a packet.
Fixed/Max Specify the handling of VLAN priority (used only if the
received packet is already tagged):
Fixed – The packet's original priority will
automatically be replaced with the Priority
specified above,
Max – The packet's original priority will be replaced
with the configured Priority only if the packet's
original priority is greater than the configured
Priority.
Ingress Limit Specify the ingress limit in kbps for packets matching
this rule.
Egress Limit Specify the egress limit in kbps for packets matching
this rule.
