WLAN Roaming
Anybus Wireless Bolt CAN supports Fast Roaming according to IEEE 802.11r. This enables a WLAN
client to roam quicker between WLAN Access Points that have the same SSID and support IEEE
802.11r. Fast Roaming is enabled as default but can be permanently disabled using AT commands.
See the AT Commands Reference Guide or the Help page in the web interface for more
information about how to set up WLAN roaming.

Anybus Wireless Bolt CAN User Manual
Layer 2 tunnel = All layer 2 data will be bridged over WLAN.
Use when multiple devices on both sides of an Ethernet network bridge must be able to
communicate via WLAN (many-to-many).
Only works between Anybus Wireless Bolt or Wireless Bridge II devices.
Layer 2 cloned MAC only = Layer 2 data from only a single MAC address (specified
below) will be bridged over WLAN (many-to-one).
Layer 3 IP forward (default) = IP data from all devices will be bridged over WLAN.
This mode must be used when using the DHCP Relay function.
When using Layer 3 IP forward in an enterprise network, such as a Cisco Wireless LAN
Controller, the connectivity may be reduced.
The cause may be:
• Multiple devices sharing a single wireless interface is not typically supported
without special configuration.
• The network cannot enforce a 1-to-1 mapping of IP to MAC addresses and must
allow propagation of broadcasted ARP messages over the wireless segment in order
to route traffic to the bridged devices.
If this for security or performance reasons is not acceptable, a setup with a single
Ethernet node connected to the Wireless Bridge is recommended.
The MAC address to use with Layer 2 cloned MAC only (see above).
The IP address to use with Layer 2 cloned MAC only (see above).
