Editing Diffserv information

To edit DiffServ information:

  1. From the Device Manager menu bar, choose IP Routing > Filter > DiffServs.
    2. The DiffServs tab opens. Packets matching a filter criteria follow the filter action specified in the filter.


Note Note: When you enable a traffic filter to modify either the DSCP or the IEEE 802.1p bits, the traffic filter also modifies the other value based on the corresponding value in the QoS ingress tables.


Field Description
Name
The IP filter name.
DiffServMatchDsFieldEnable
Set to enable to allow a match on the DS field (8 bits), which is composed of the 6-bit DS codepoint (DSCP) and the 2-bit reserved fields.
MatchDscp
This field is used to specify the match value for the DSCP. The user must enter a 6-bit binary value, and, by default, the value is 000000. If the DSCP in the incoming packet matches this value, then this filter is applied to the packet.
MatchDscpReserved
This field is reserved for future use. The default is a 2-bit binary value of 00 and should not be changed.
ModifyIeee8021PEnable
Set to enable to allow the IEEE 802.1p field to be modified on packets ingressing DiffServ access ports only. By default, the IEEE 802.1p field is set to zero.
ModifyIeee8021P
If you do not want the IEEE 802.1p field set to zero, use this field to specify the value of the IEEE 802.1p field. You first must enter a value, set the ModifyIeee8021PEnable field to disable, and then set it to enable.
ModifyDscpEnable
Set to enable to allow the DSCP (6 bits) to be modified on packets ingressing DiffServ access ports only. By default, the DS codepoint is set to 000000.
ModifyDscp
If you do not want the DSCP set to zero, use this field to specify the value of the DSCP. You first must enter a 6-bit value, set the ModifyDscpEnable field to disable, and then set it to enable.
DiffServTrafficProfileId
This field is used to specify which traffic profile should be applied to packets matching this filter. A zero value means do not apply any traffic profile.

  1. Click any of the fields with white backgrounds. You will have the option either to select a new value from the pop-up menu or to enter a new value.
    2. If you change a value in the ModifyDscp or the ModifyIeee8021P field, you must set the ModifyDscpEnable or ModifyIeee8021PEnable field to disable. Click the Apply and the Refresh buttons, set that field to enable, and then click the Apply and the Refresh buttons again.
  2. Click Apply.
  3. Click Refresh.
  4. After you finish editing the filter, you must reapply the ports associated with that filter.
