# Support

The following shows Bridge module APIs available for each permissions.

# Bridge Class

# new Bridge(brname)

• brname {String} Bridge net device name.
• Returns: {Object} Returns bridge object.

Create a bridge device with the specified name.

# Example

var bridge = new Bridge('brdev0');

# Bridge.add(brname)

• brname {String} Bridge net device name.
• Returns: {Object} Returns bridge object.

Same as new Bridge(brname).

# Bridge Object

# bridge.index

• {Integer}

Bridge device network interface index number. A network interface index greater than 0 is considered valid.

# bridge.subif

• {Array}

List of network interface contained within the bridge device.

# Example

var bridge = new Bridge('brdev0');

bridge.ifAdd('en1');
bridge.ifAdd('wl3');

console.log(bridge.subif);  // ['en1', 'wl3']

# bridge.delete()

• Returns: {Boolean} Whether the operation was successful.

Remove the previously created bridge device, and the network interfaces in the bridge device will be re-added to the system. This object cannot be operated here after the bridge device is removed.

# Example

var bridge = new Bridge('brdev0');

bridge.delete();
bridge = null;

# bridge.ifAdd(ifname)

• ifname {String} Network interface name.
• Returns: {Boolean} Whether the operation was successful.

Add a network interface to the bridge device, currently only supports Ethernet MAC standard.

# bridge.ifDelete(ifname)

• ifname {String} Network interface name added before.
• Returns: {Boolean} Whether the operation was successful.

Remove a previously added network interface from the bridge device. The removed network interface will be recognized by the operating system again and added to the working device.

# Example

var bridge = new Bridge('brdev0');

bridge.ifAdd('en1');
bridge.ifDelete('en1');
