If DHCP is enabled ( DHCP Enable (3.02.005) ) this parameter becomes read-only and, until a default gateway is allocated to the module, will display 0.0.0.0.

If DHCP is disabled the module will initialise, on reset or power cycle, with the default gateway stored for the parameter.

Parameter | 3.02.009 Primary DNS
--- | ---
Short description | Sets and/or shows the primary DNS address of the module
Minimum | 0 (Display: 0.0.0.0) | Maximum | 4294967295 (Display: 255.255.255.255)

Display Format | IP Address | Decimal Places | 0
Coding | RW, BU

The module can use this IP address when it wishes to resolve the IP address for a domain name. This parameter performs the same function as the Secondary DNS parameter Secondary DNS (3.02.010) , however the address specified in this parameter will be tried first. Only when this address is unsuccessful will the Secondary DNS address be tried.

If DHCP is enabled ( DHCP Enable (3.02.005) ) this parameter becomes read-only and, until a primary DNS address is allocated to the module, will display 0.0.0.0.

If DHCP is disabled the module will initialise, on reset or power cycle, with the primary DNS address stored for the parameter.

Parameter | 3.02.010 Secondary DNS
--- | ---
Short description | Sets and/or shows the secondary DNS address of the module
Minimum | 0 (Display: 0.0.0.0) | Maximum | 4294967295 (Display: 255.255.255.255)
Default | 0 (Display: 0.0.0.0) | Units |
Type | 32 Bit User Save | Update Rate | DHCP enabled : write on event; DHCP disabled : read on reset
Display Format | IP Address | Decimal Places | 0
Coding | RW, BU

The module can use this IP address when it wishes to resolve the IP address for a domain name. This parameter performs the same function as the Primary DNS parameter Primary DNS (3.02.009) , however the address specified in this parameter will be tried only when the Primary DNS address is unsuccessful.

If DHCP is enabled ( DHCP Enable (3.02.005) ) this parameter becomes read-only and, until a secondary DNS address is allocated to the module, will display 0.0.0.0.

If DHCP is disabled the module will initialise, on reset or power cycle, with the secondary DNS address stored for the parameter.

Parameter | 3.02.011 MAC Address
--- | ---

The 48-bit MAC address of the module.

Parameter | 3.02.024 Ethernet MTU
--- | ---
Short description | Specifies the MTU for the Ethernet interface
Minimum | 158 | Maximum | 1500
Default | 1500 | Units | Bytes
Type | 16 Bit User Save | Update Rate | Read on module reset

Specifies the MTU (Maximum Transmitable Unit) in bytes allowed by the Ethernet interface.

Parameter | 3.02.025 Gateway Mode
--- | ---
Short description | Specifies the operation mode of the gateway
Minimum | 0 | Maximum | 2
Default | 0 | Units |
Type | 8 Bit User Save | Update Rate | Read on module reset
Display Format | Standard | Decimal Places | 0
Coding | RW, TE, BU

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.

Parameter | 3.02.030 VLAN Enable
--- | ---
Short description | Enables VLAN tagging
Minimum | 0 | Maximum | 1
Default | 0 | Units |
Type | 1 Bit User Save | Update Rate | Background read
Display Format | Standard | Decimal Places | 0
Coding | RW

Controls whether the module will use VLAN tagging.

When used in conjunction with Drive VLAN ID (3.02.031) network traffic from the interface will be tagged with the chosen VLAN identifier.

When default values for Drive VLAN ID (3.02.031) 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.
