Detects and uses network topologies that allow a faster convergence of thespanning tree, without creating forwarding loops.Running Configuration FileContains all startup configuration file commands, as well as all commands entered during the current session.After the switch module is powered down or rebooted, all commands stored in the Running Configuration fileare lost.SSegmentationDivides LANs into separate LAN segments for bridging. Segmentation eliminates LAN bandwidth limitations.ServerA central computer that provides services to other computers on a network. Services may include file storage andaccess to applications.SNMPSimple Network Management Protocol. Manages LANs. SNMP based software communicates with networkdevices with embedded SNMP agents. SNMP agents gather network activity and device status information, andsend the information back to a workstation.SNTPSimple Network Time Protocol. SNTP assures accurate network switch clock time synchronization up to themillisecond.SoCSystem on a Chip. An ASIC that contains an entire system. For example, a telecom SoC application can containa microprocessor, digital signal processor, RAM, and ROM.Spanning Tree ProtocolPrevents loops in network traffic. The Spanning Tree Protocol (STP) provides tree topography for anyarrangement of bridges. STP provides one path between end stations on a network, eliminating loops.SSHSecure Shell. Permits logging to another computer over a network, execute commands on a remote machine, andmove files from one machine to another. Secure Shell provides strong authentication and securecommunications methods over insecure channels.Startup ConfigurationRetains the exact switch module configuration when the switch module is powered down or rebooted.
