protocol – A set of rules for communication between devices on a network. The rules dictate format, timing, sequencing, and error control.
resilient link – A pair of ports that can be configured so that one will take over data transmission should the other fail. See also main port and standby port.
RMON – Remote Monitoring. Subset of SNMP MIB II, which allows monitoring and management capabilities by addressing up to ten different groups of information.
RPS – Redundant Power System. A device that provides a backup source of power when connected to the Switch.
server farm – A cluster of servers in a centralized location serving a large user population.
SLIP – Serial Line Internet Protocol. A protocol that 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 networking equipment and may be used to manage many aspects of network and end station operation.
Spanning Tree Protocol – (STP) A
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 that 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
VLT – Virtual LAN Trunk. A
VT100 – A type of terminal that uses ASCII characters. VT100 screens have a text- based appearance.
