RSTP Rapid Spanning Tree Protocol. Detects and uses network topologies that allow a faster convergence of the spanning tree, without creating forwarding loops. Running Configuration File Contains all Startup file commands, as well as all commands entered during the current session. After the device is powered down or rebooted, all commands stored in the Running Configuration file are lost. S Segmentation Divides LANs into separate LAN segments for bridging and routing. Segmentation eliminates LAN bandwidth limitations. Server A central computer that provides services to other computers on a network. Services may include file storage and access to applications. SNMP Simple Network Management Protocol. Manages LANs. SNMP based software communicates with network devices with embedded SNMP agents. SNMP agents gather network activity and device status information, and send the information back to a workstation. SNTP Simple Network Time Protocol. SNTP assures accurate network switch clock time synchronization up to the millisecond. SoC System on a Chip. An ASIC that contains an entire system. For example, a telecom SoC application can contain a microprocessor, digital signal processor, RAM, and ROM. Spanning Tree Protocol Prevents loops in network traffic. The Spanning Tree Protocol (STP) provides tree topography for any arrangement of bridges. STP provides one path between end stations on a network, eliminating loops. Startup Configuration Retains the exact device configuration when the device is powered down or rebooted. Subnet Sub-network. Subnets are portions of a network that share a common address component. On TCP/IP networks, devices that share a prefix are part of the same subnet. For example, all devices with a prefix of 157.100.100.100 are part of the same subnet. Subnet Mask Used to mask all or part of an IP address used in a subnet address. Switch Filters and forwards packets between LAN segments. Switches support any packet protocol type. 180 Glossary
