Glossary
SNMP
Simple Network Management Protocol. Standardized protocol for transporting network
management information.
Spanning Tree
The Spanning Tree protocol (STP) allows redundant transmission paths. This prevents
circulating frames and, if a fault develops, provides an alternative path within 20 - 30
seconds (reconfiguration time).
Store and forward
In this switching technique, the entire frame is read in, before it is forwarded by the
IE Switch X-300. A packet is only passed on if it is error-free.
TELNET
With this protocol, an interactive connection can be established to another device in the LAN
or on the Internet. The user then has the same options as when directly connected to this
device with a terminal.
TFTP
Trivial File Transfer Protocol. A simple, UDP-based protocol for data transfer. Due to its
limited size, it can also be used by network nodes with little ROM.
TP port
Port with a TP connector (RJ-45 jack)
VLAN
Virtual LAN within a physically existing network.
WBM
Web Based Management. With WBM, configuration and diagnostics are handled with an
Internet browser. Entries made by the user are sent to the IE Switch X-300 using the HTTP
protocol and the IE Switch X-300 transfers its replies by HTTP to the user.
