Learning Table menu command

Assignment of MAC address and port
The learning table contains the information about whether a MAC address can be reached
over the wired Ethernet interface or over the wireless interfaces. The SCALANCE W-700
obtains this information from the active data exchange. The learning table also contains
information on clients and on up to 8 devices connected downstream from it operating in the
layer 2 tunneling mode.
5.6.6.5

ARP Table menu command

Assignment of MAC address and IP address
The ARP protocol (Address Resolution Protocol) obtains the corresponding MAC address of
a known IP address. The page of this menu command also indicates the interface over
which an address can be reached. The last column indicates how the information was
obtained (for example "dynamic" if it was obtained during operation or "static" if it was
configured).
5.6.6.6

Spanning Tree menu command

Note
The "Spanning tree" menu command is available only when you use the SCALANCE W78x
in access point mode.
Avoiding loops on redundant connections
The spanning tree algorithm allows network structures to be created in which there are
several connections between two stations. Spanning tree prevents loops being formed in the
network by allowing only one path and deactivating the other (redundant) ports for data
traffic. If there is an interruption, the data can be sent over an alternative path. The
functionality of the spanning tree algorithm is based on the exchange of configuration and
topology change frames.
