Global Configuration 

Diffserv Rule

Specify Add, Delete, or No Set to add a rule, 

delete a rule, or perform no action when the 

Submit button is clicked on.

Activate

Specify whether the rule you are adding is 

active.

DS Value

Specify the Differentiated Services value. The 

DS Value of a packet is a hexadecimal value 

calculated from the upper six bits of an eight-bit 

field in the packet's IP header.

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.
