Value | Text
0 | Switch
1 | Gateway
2 | Strict Gateway

Specifies the operation mode of the gateway. By default the gateway is disabled and the switch operates in normal switch mode, by enabling the gateway mode all packets are filtered by the module and prioritised before being forwarded on. In strict mode the gateway will drop packets from unsupported protocols.

VLAN must be enabled VLAN Enable (4.02.030) when the gateway is enabled.

Parameter | 4.02.030 VLAN Enable

Controls whether the module will use VLAN tagging.

When used in conjunction with Drive VLAN ID (4.02.031) network traffic from the interface will be tagged with the chosen VLAN identifier.

When default values for Drive VLAN ID (4.02.031) is set, enabling this parameter will add VLAN prioritisation to all packets helping to ensure real-time packets are not delayed by those of lower priority. If disabled, prioritisation will use the Diffserv field in IP traffic only, meaning non-IP traffic can still affect real-time IP traffic.
