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 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 file
are lost.
S
Segmentation
Divides LANs into separate LAN segments for bridging. 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.
SSH
Secure Shell . Permits logging to another computer over a network, execute commands on a remote machine, and
move files from one machine to another. Secure Shell provides strong authentication and secure
communications methods over insecure channels.
Startup Configuration
Retains the exact switch module configuration when the switch module is powered down or rebooted.
