Class of Service

There are four Class of Service schemes provided: TCP/UDP port, IP ToS/DS, 802.1p and

Physical port. The switch treats CoS schemes in the following priority: TCP/UDP port >

IP ToS/DS > 802.1p > Physical port. It means that TCP/UDP CoS will override all other

settings.

Any of three CoS schemes – TCP/UDP port, IP ToS/DS and 802.1p – is mapped to "high", so

if the data packet hit any of these CoS rules, it will be treated as high priority packet.

1) TCP/UDP Port

The Class of Service for TCP/UDP port number allows the network administrator to assign

the specific application to a priority queue.
