DiffServ Table
[DiffServToVlanPriority]
This ini file table parameter allows you to configure
VLAN tag priorities.The format of this ini file is as follows:
[ DiffServToVlanPriority ]
FORMAT DiffServToVlanPriority_Index =
DiffServToVlanPriority_DiffServ,
DiffServToVlanPriority_VlanPriority;
[ \DiffServToVlanPriority ]
For example:
DiffServToVlanPriority 0 = 48, 7;
DiffServToVlanPriority 1 = 46, 6;
DiffServToVlanPriority 2 = 40, 6;
DiffServToVlanPriority 3 = 26, 4;
DiffServToVlanPriority 4 = 10, 2;
Notes:
 You can configure up to 64 VLAN tag priorities (i.e.,
indices 0-63).
 The valid range of the parameter DiffServ is 0-63.
 The valid range of the parameter VlanPriority is 0-7.
