5: Network Settings Bridge This page allows configuration of a bridge between an Ethernet interface and a WLAN interface. A bridge represents a relationship between the interface minor numbers. For example, br0 is a bridge between eth0 and wlan0. When a bridge is enabled, the Wired (eth0) Network configuration is used for configuring direct connections into the device over the primary interface; the Wireless (wlan0) Network configuration is ignored. Both the Ethernet and WLAN link configurations are used the same as when the bridge is disabled. Bridging MAC Address specifies the MAC address of bridgeable traffic between the Ethernet and WLAN interfaces. When bridging is active, this MAC Address will be used as the MAC address of the WLAN interface. Packets received on the Ethernet interface from this address will be bridged to the WLAN interface (except traffic directed at the Primary Interface). If this field is not configured, then the device waits for the first packet to arrive on the Ethernet interface and uses the source address as the bridging address. Bridging IP Address specifies the IP address of the bridged client. When bridging is active, this IP Address will be used to create a static route between this device and the bridged client. This route is required for connecting to the bridged client from devices connected via the access point network and from this device. If Auto Detect IP Address is enabled, then the device will attempt to learn the IP Address by using the source or destination IP address of packets arriving on the Ethernet interface. Warning: Enabling Auto Detect IP Address may affect the performance of running processes during the learning phase. During initialization, the bridging subsystem enables and controls both eth0 and wlan0 networks. These are important aspects to keep in mind:  If the eth0 physical link is inactive, wlan0 is the primary interface.  If the eth0 physical link is active, eth0 is the primary interface. When the eth0 link is active, the wlan0 link is established. Additionally, the bridging MAC address is acquired using preconfiguration or auto-detection, and bridging enters the Active state. If either link goes down, bridging reverts to the Inactive state. When in the Active state, all packets that arrive on the wlan0 interface are bridged out (through) the eth0 interface. Similarly, all packets that arrive on the eth0 interface are bridged out (through) the wlan0 interface. However, exceptions to this behavior include:  Ethernet packets directed specifically to the Ethernet (eth0) MAC address are terminated internally and are not bridged to WLAN.  An ARP request for the primary interface IP address is terminated internally and is not bridged to the WLAN. Ethernet packets that do not originate from the bridging MAC Address are discarded. You can configure a bridge between an Ethernet interface and a WLAN interface. A bridge represents a relationship between the minor numbers of the interface. For example, br0 is a bridge between eth0 and wlan0. PremierWave® 2050 Enterprise Wi-Fi® IoT Module User Guide 25

Bridge

This page allows configuration of a bridge between an Ethernet interface and a WLAN interface. A

bridge represents a relationship between the interface minor numbers. For example, br0 is a

bridge between eth0 and wlan0.

When a bridge is enabled, the

Wired (eth0) Network

configuration is used for configuring direct

connections into the device over the primary interface; the

Wireless (wlan0) Network

configuration

is ignored. Both the Ethernet and WLAN link configurations are used the same as when the bridge

is disabled.

Bridging MAC Address specifies the MAC address of bridgeable traffic between the Ethernet and

WLAN interfaces. When bridging is active, this MAC Address will be used as the MAC address of

the WLAN interface. Packets received on the Ethernet interface from this address will be bridged

to the WLAN interface (except traffic directed at the Primary Interface). If this field is not

configured, then the device waits for the first packet to arrive on the Ethernet interface and uses

the source address as the bridging address.

Bridging IP Address specifies the IP address of the bridged client.

When bridging is active, this IP Address will be used to create a static route between this device

and the bridged client.

This route is required for connecting to the bridged client from devices connected via the access

point network and from this device.

If Auto Detect IP Address is enabled, then the device will attempt to learn the IP Address by using

the source or destination IP address of packets arriving on the Ethernet interface.

Warning:

Enabling Auto Detect IP Address may affect the performance of running

processes during the learning phase.

During initialization, the bridging subsystem enables and controls both eth0 and wlan0 networks.

These are important aspects to keep in mind:



If the eth0 physical link is inactive, wlan0 is the primary interface.



If the eth0 physical link is active, eth0 is the primary interface.

When the eth0 link is active, the wlan0 link is established. Additionally, the bridging MAC address

is acquired using preconfiguration or auto-detection, and bridging enters the Active state. If either

link goes down, bridging reverts to the Inactive state.

When in the Active state, all packets that arrive on the wlan0 interface are bridged out (through)

the eth0 interface. Similarly, all packets that arrive on the eth0 interface are bridged out (through)

the wlan0 interface. However, exceptions to this behavior include:



Ethernet packets directed specifically to the Ethernet (eth0) MAC address are terminated

internally and are not bridged to WLAN.



An ARP request for the primary interface IP address is terminated internally and is not bridged

to the WLAN.

Ethernet packets that do not originate from the bridging MAC Address are discarded.

You can configure a bridge between an Ethernet interface and a WLAN interface. A bridge

represents a relationship between the minor numbers of the interface. For example, br0 is a bridge

between eth0 and wlan0.
