DS Mask Specify the DS mask. The DS Mask is a hexadecimal
value that indicates which of the DSCP's upper six bits
will be utilized in considering a packet's DSCP type.
Default is FC, indicating that all of the DSCP's upper
six bits will be used in calculating the packet's DS
Value.
Allow Tag/Untag on Ingress
Pkt.
Specify tag or untag. Tag indicates that ingress
packets already matched to the Diffserv 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 Diffserv
Rule cannot have a VLAN tag to be further
considered; packets with a VLAN tag will be dropped.
VLAN Specify a VLAN ID range. For each Global Diffserv
Rule, if you selected Tag for Allow Tag/Untag, the
VLAN field should specify either an acceptable single
VLAN, or an acceptable VLAN Range, for VLAN tags
on ingress packets. 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.
