12.7Configuration Example 6 - QoS Marking with Port Role Combination set for Un-restricted using ACL’s

With a port role combination of un-restricted, the DSCP value is passed as-is and is not looked at by the ERS5500 internal QoS mapping. This does not apply to the p-bit which is looked at, honoured, and mapped according to the QoS priority mapping table. If you wish to apply QoS to the DSCP value on an unrestricted port member, either ACL’s or policies must be defined where you need to map the DSCP value to the appropriate egress queue. For this example, we will demonstrate how to configure the ERS5500 to support internal QoS mapping for various DSCP values.

Figure 6: DSCP Mapping via Un-restricted Port Role

For this example, assume we wish to accomplish the following in regarded to the untagged VLAN

5 ingress port members:

Set a port role of un-restricted with port members 3 to 6

Select queue set 8 with 8 queues

For ingress port members 3-5, we wish to map the following DSCP values. Please use the “show qos queue-set-assignment command to display the

oFor DSCP 0x12 (Silver CoS), map to egress queue 5

oFor DSCP 0x1a (Gold CoS), map to egress queue 4

oFor DSCP 0x22 (Platinum CoS), map to egress queue 3 To accomplish the above, please follow the configuration steps below.

12.7.1ERS5500 Configuration

12.7.1.1 Create VLAN 5

ERS5500: Step 1 – Remove port members from default VLAN and create VLAN 5

5500(config)#vlan members remove 1 3-6

5500(config)#vlan create 5 type port

5500(config)# vlan members add 5 3-6

12.7.1.2 Create Queue Set 8

ERS5500: Step 1 – Add queue set 8; please note that you must reboot the switch for the queue set to take effect

5500(config)#qos agent queue-set 8

5500(config)#boot
