802.1d STP
Spanning Tree Protocol. It is an algorithm to prevent network from forming. The STP protocol allows
net work to provide a redundant link in the event of a link failure. It is advise to turn on this option for
multi-link bridge network.
802.1Q Tag VLAN
In 802.1Q VLAN, the VLAN information is written into the Ethernet packet itself. Each packet carries
a VLAN ID (called Tag) as it traveled across the network. Therefore, the VLAN configuration can be
configured across multiple switches. In 802.1Q spec, possible 4096 VLAN ID can be created.
Although for some devices, they can only view in frames of 256 ID at a time.
802.1x
802.1x is a security standard for wired and wireless LANs. In the 802.1x parlance, there are usually
supplicants (client), authenticator (switch or AP), and authentication server (radius server) in the
network. When a supplicants request a service, the authenticator will pass the request and wait for
the authentication server to grant access and register accounting. The 802.1x is the most widely
used method of authentication by WISP.
Ad-hoc
A Peer-to-Peer wireless network. An Ad-hoc wireless network do not use wireless AP or router as the
central hub of the network. Instead, wireless client are connected directly to each other. The
disadvantage of Adhoc network is the lack of wired interface to Internet connections. It is not
recommended for network more than 2 nodes.
Access Point (AP)
The central hub of a wireless LAN network. Access Points have one or more Ethernet ports that can
connect devices (such as Internet connection) for sharing. Multi-function Access Point can also
function as an Ethernet client, wireless bridge, or repeat signals from other AP. Access Points
typically have more wireless functions comparing to wireless routers.
