The KGS can be configured to have 8 output CoS queues (Q0~Q7) per port, into which each packet is placed. Q0 is the highest priority Queue. Each packet‘s 802.1p priority determines its CoS queue. You need to bind VLAN priority/queue mapping profile to each port, for every VLAN priority need assign a traffic descriptor for it. The traffic descriptor defines the shape parameter on every VLAN priority for Ethernet interface. Currently KGS supports Strict Priority and SP+WRR (Weighted Round Robin) scheduling methods on each port. Please find the detail reference on ISW user manual.
Default Priority and Queue mapping is as follows:
| Priority0 | Priority1 | Priority2 | Priority3 | Priority4 | Priority5 | Priority6 | Priority7 |
| Queue0 | Queue1 | Queue2 | Queue3 | Queue4 | Queue5 | Queue6 | Queue7 |
| SPQ | SPQ | SPQ | SPQ | SPQ | SPQ | SPQ | SPQ |
