User manual

Server farm: A cluster of servers in a centralized location serving a large user population.
SLIP: Serial Line Internet Protocol:
A protocol, which allows IP to run over a serial line connection.
SNMP: Simple Network Management Protocol:
A protocol originally designed to be used in managing
TCP/IP internets. SNMP is presently implemented on a wide range of computers and net-
working equipment and may be used to manage many aspects of network and end station
operation.
Spanning Tree Protocol (STP): A bridge-based system for providing fault tolerance on networks. STP works by
allowing you to implement parallel paths for network traffic, and ensure that
redundant paths are disabled when the main paths are operational and enabled if
the main paths fail.
Stack: A group of network devices that are integrated to form a single logical device.
Standby port: The port in a resilient link that will take over data transmission if the main port in the link
fails.
Switch: A device, which filters, forwards and floods packets based on the packet's destination address.
The switch learns the addresses associated with each switch port and builds tables based on
this information to be used for the switching decision.
TCP/IP: A layered set of communications protocols providing Telnet terminal emulation, FTP file
transfer, and other services for communication among a wide range of computer equipment.
Telnet: A TCP/IP application protocol that provides virtual terminal service, letting a user log in to
another computer system and access a host as if the user were connected directly to the host.
TFTP: Trivial File Transfer Protocol:
Allows you to transfer files (such as software upgrades) from a
remote device using your switch's local management capabilities.
UDP: User Datagram Protocol:
An Internet standard protocol that allows an application program on
one device to send a datagram to an application program on another device.
VLAN: Virtual LAN:
A group of location- and topology-independent devices that communicate as if
they are on a common physical LAN.
VLT: Virtual LAN Trunk:
A Switch-to-Switch link which carries traffic for all the VLANs on each
Switch.
VT100: A type of terminal that uses ASCII characters. VT100 screens have a text-based appearance.
