GL-4 ES3000 User Guide
Multicast | A single packet sent to a specific group of end stations on a network. |
Port monitoring | The ability to monitor the traffic passing through a port on a device to analyze |
| network characteristics and perform troubleshooting. |
Port speed | The speed that a port on a device uses to communicate with another device or the |
| network. |
Port trunking | The ability to combine multiple ports on a device to create a single, |
| connection. |
Protocol | A set of rules for communication between devices on a network. |
Quality of Service | A term to describe delay, throughput, bandwidth, and other factors that measure the |
| service quality provided to a user. |
Segment | A section of a LAN that is connected to the rest of the network using a switch, bridge, |
| or repeater. |
SNMP | Simple Network Management Protocol. An IETF standard protocol for managing |
| devices on a TCP/IP network. |
Spanning Tree | A technique that detects loops in a network and logically blocks the redundant paths, |
| ensuring that only one route exists between any two LANs. |
Spanning Tree Protocol (STP) | A protocol that finds the most efficient path between segments of a |
| bridged network. STP allows redundant switches and bridges to be used for network |
| resilience, without the broadcast storms associated with looping. If a switch or |
| bridge falls, a new path to a redundant switch or bridge is opened. |
Switch | A device that interconnects several LANs to form a single logical LAN that comprises |
| of several LAN segments. Switches are similar to bridges, in that they connect LANs |
| of a different type; however they connect more LANs than a bridge and are generally |
| more sophisticated. |
TCP/IP | Transmission Control Protocol/Internet Protocol. This is the name for two of the most |
| well known protocols developed for the interconnection of networks. Originally a |
| UNIX standard, TCP/IP is now supported on almost all platforms, and is the protocol |
| of the Internet.TCP relates to the content of the data traveling through a network - |
| ensuring that the information sent arrives in one piece when it reaches its |
| destination.IP relates to the address of the end station to which data is being sent, |
| as well as the address of the destination network. |
Telnet | A TCP/IP application protocol that provides a virtual terminal service, allowing a user |
| to log into another computer system and access a device as if the user were |
| connected directly to the device. |
TFTP | Trivial File Transfer Protocol. Allows the transfer of files (such as software upgrades) |
| from a remote device using the local management capabilities of the Switch. |
