A CoS profile is used to map an input frame to a Layer 2 class of service based on the conformance level (Green/Yellow) of the incoming traffic and on the value of the following information for the incoming frames:

  • PCP: p-bits in 802.1Q / 802.1Q-in-Q tags.
  • IP Precedence: IP precedence bits in the IPv4 ToS byte or in the IPv6 Traffic Class byte.
  • DSCP: DSCP bits in the IPv4 ToS byte or in the IPv6 Traffic Class byte.

To set up a CoS profiles configuration job

  1. Access the page Commission â–¶ Jobs.

  2. Set all common configuration job settings, as described in "Creating Configuration Jobs in GUI Mode" and "Creating Configuration Jobs Using Data Sets".

  3. Select CoS Profiles in the left pane. The CoS profiles tab is displayed.

  4. Complete all fields in the CoS profiles tab as required. For more information on specific parameters, see the table below.

  5. Use the Add Button_New_Generic.png button or Duplicate Button_Duplicate.png button to add CoS profiles as required.

    Note: When duplicating a row, always select the row to duplicate before clicking the Duplicate Button_Duplicate.png button.

  6. Click Apply, then click Close.

  7. Click the Refresh Button_Refresh_Generic.png button to refresh the user interface.

General

Parameter Description
Name The name identifying the CoS profile.
Type Specifies the type of priority the CoS profile will use when mapping incoming frames to a Layer-2 class of service. The type you choose may be one of the following:
  • PCP: Priority Code Point mapping.
  • IP Precedence: IP precedence mapping.
  • IP PRE: IP precedence mapping.
  • DSCP: Differentiated Services Code Point mapping.
Decode DEI Enable this checkbox to make the unit decode the pre-marking color from the DEI bit (Drop Eligible Indicator). Otherwise, the user-defined pre-color is used.
Encode Using DEI Enable this checkbox to make the unit control the DEI bit in an S-VLAN tag. If this field is enabled and the outgoing frame is marked yellow, then the DEI bit is set to 1; otherwise, the DEI bit is set to 0.

Priority Type Lists (PCP 0-3, PCP 4-7, IP Precedence 0-3, IP Precedence 4-7, DSCP 0-3)

Parameter Description
Marking The pre-marking color to assign to the input frame that has this PCP, IP precedence or DSCP value.
Green The CoS value for use with outgoing green frames. This value is selected if either of the following is true:
  • The result of the bandwidth regulator assigned to this entry is green.
  • The pre-marking color is green, and no bandwidth regulator is assigned to this entry.
Yellow The CoS value for use with outgoing yellow frames. This value is selected if any of the following is true:
  • The result of the bandwidth regulator assigned to this entry is yellow.
  • The pre-marking color is yellow, and no bandwidth regulator is assigned to this entry.
  • The frame has passed through a color-aware bandwidth policer and has been marked as yellow (due to the depletion of its CIR bucket).
