Configuring CoS

The set of rules included in a role, along with any access or CoS defaults, determine how all network traffic of any client assigned to the role will be handled. For example, a Doctor role can be assigned a higher priority CoS and default access control due to the sensitivity and urgency of services that a doctor provides to patients.

  1. Go to Configure > Policy > Class of Service.
  2. Select Add, or select an existing Class of Service from the list.
  3. Configure the following parameters:
    Name
    Naming should reflect the priority for your organization and be easily recognized by your IT team, such as Bulk Data or Critical Data.
    Priority
    Define how the Layer 2 priority of the packet will be marked. Priority 0 is the highest priority.
  4. For ToS/DSCP, define how the Layer 3 ToS/DSCP will be marked. Enter a hexadecimal value in the 0x (DSCP:) field, or select Configure to open the ToS/DSCP dialog box.
  5. In the CoS dialog box, set the Mask value.
    Mask
    Select a hexadecimal value to use for the ToS/DSCP value. For example, if the mask is 0xF0, then only the four most significant bits of the ToS of the received packets are marked. So, if the received ToS is 0x33 and the ToS marking is set to 0x2A, then the resulting ToS is 0x23.
  6. Specify the inbound and outbound rate limits, and select OK.
  7. Click to add a new bandwidth rate.
  8. Select Save.
