SNMP (Simple Network Management Protocol)
SNMP is a popular network management protocol in the TCP/IP and
SPX/IPX protocol suite. SNMP allows TCP/IP and SPX/IPX sites to
exchange configuration and status information. It uses management
programs called "agents" to monitor network traffic. SNMP stores the
information it collects in the Management Information Base (MIB). Your
network administrator can use management software, such as MobileLAN
manager, interacting with the MIB to obtain information about network
activity.
spanning tree
A form of network organization in which each device on the network has
only one path to the root. The access points automatically configure into a
self-organized network that provides efficient, loop-free forwarding of
frames through the network.
splitter
The MobileLAN splitter converts 48V input power to 5V or 3.3V output
power. If you want to use power over Ethernet, you plug the access point
into the splitter and then you plug the splitter into a MobileLAN power
bridge.
The WA22, WA21, and 2100 do not use a splitter.
SWAP (Secure Wireless Authentication Protocol)
This protocol creates secure wireless hops if you enable secure IAPP. It
forces access points to authenticate each other using an EAP-MD5
challenge.
Telnet Gateway
A software feature in Release 2.1 that allows the access point to keep telnet
sessions alive even when the wireless client is idle or disconnected for any
reason (because the client has roamed out of range, been powered off, lost
battery power, etc.).
TLS (Transport Layer Security)
An EAP authentication type that not only requires a certificate on the
authentication server, but also one on the end device. There is both server
and client side authentication before the end device can communicate
with the network.
TTLS (Tunneled Transport Layer Security)
An EAP authentication type that only requires a certificate on the
authentication server. End devices have a user name and password that
proves that they are authorized to communicate with the network.
