TCP Negotiation
When TCP negotiation is enabled, the TCP/IP stack applies the user-specified ToS priority during the TCP negotiation.
When the controller acts as a server, disable TCP negotiation. The controller uses the default value of 0 for ToS during the 3-way TCP communication and then applies the defined ToS value when connected.
Whether enabled or disabled, the ToS value may change after the completion of the TCP negotiation if another service has a more specific rule for the port.
TIP:
To apply a connection by ToS during the enabled TCP
negotiation, define Protocol and Port values; the Peer Address must remain empty.
When setting the Quality of Service, define the following:
Protocol | The type of protocol. Possible values are Unused, UDP, or TCP. The default value is Unused. |
Port | The port number. If the AADvance controller initiates the connection, the service
number of the device being connected to. Possible values range from 0 to 65535. The default value is 0. |
Peer Address | When the defined protocol is TCP, the address of the device being connected to.
Setting a peer address is optional and only required when needing to set the
priority for traffic from one specific device. The default value is 0.0.0.0. To prioritize traffic coming from devices using the same port to communicate with
the AADvance controller, leave the Peer Address at 0.0.0.0. |
ToS | The value of the priority. Possible values are Low, Medium, High, or a value ranging from 0 to 255. The
default value is 0. When setting the value of ToS to 255, the networking equipment may interpret the
packet incorrectly. It is recommended to use a maximum value of 254 for ToS. |
