xStack® DGS-3200 Series Layer 2 Gigabit Ethernet Managed Switch latency: The delay between the time a device receives a packet and the time the packet is forwarded out of the destination port. line speed: See baud rate. main port: The port in a resilient link that carries data traffic in normal operating conditions. MDI - Mediu m Dependent Interface: An Et hernet port co nnection where t he transmitter o f one d evice is co nnected t o the receiver of another device. MDI-X - Me dium Dependent Interface Cross-over: An Et hernet port connection where the internal transmit and recei ve lines are crossed. MIB - Management Information Base: Stores a device's management charact eristics and parameters. M IBs are used by t he Simple Net work M anagement P rotocol (SNMP) t o c ontain at tributes of t heir m anaged sy stems. The S witch co ntains i ts own internal MIB. multicast: Si ngle packets c opied t o a specific subset of network addresses. These address es are specified in th e destinationaddress field of the packet. 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 o ne will take over data transmission should the other fail. See also main port and standby port. RJ-45: Standard 8-wire connectors for IEEE 802.3 10BASE-T networks. RMON: Remote Monitoring. A subset of SNMP MIB II that 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 which allows IP to run over a serial line connection. SNMP - Simple Network Ma nagement Prot ocol: A protocol o riginally desi gned t o be u sed i n managing TC P/IP i nternets. SNMP i s p resently im plemented on a wide ran ge o f c omputers and networking e quipment and m ay be use d t o manage m any aspects of network and end station operation. Spanning Tre e Protoc ol (STP): A bridge-based system for providing fault tolerance on networks. STP works by allowing the user t o im plement p arallel p aths for n etwork tr affic, and en sure th at redundant p aths ar e disabled wh en th e main p aths ar e operational and enabled if the main paths fail. standby port: The port in a resilient link that will take over data transmission if the main port in the link fails. switch: A d evice wh ich filters, forwards an d flood s packets b ased on the p acket's destin ation add ress. Th e switch learn s t he 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 - Triv ial File Tra nsfer Protocol: Allows the user to transfer files (such as software upgrades) from a remote device using your switch's local management capabilities. UDP - User Da tagram Protocol: An I nternet st andard pr otocol t hat allows a n a pplication p rogram on one device t o se nd a datagram to an application program on another device. VLAN - Vir tual LA N: A group of location- and topology-independent devices that communicate as i f they are on a c ommon 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. . 281
