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.
