SHA
SHA is an acronym for Secure Hash Algorithm. It designed by the National Security Agency (NSA) and published by
the NIST as a U.S. Federal Information Processing Standard. Hash algorithms compute a fixed-length digital
representation (known as a message digest) of an input data sequence (the message) of any length.
Shaper
A shaper can limit the bandwidth of transmitted frames. It is located after the ingress queues.
SMTP
SMTP is an acronym for Simple Mail Transfer Protocol. It is a text-based protocol that uses the Transmission Control
Protocol (TCP) and provides a mail service modeled on the FTP file transfer service. SMTP transfers mail messages
between systems and notifications regarding incoming mail.
SNMP
SNMP is an acronym for Simple Network Management Protocol. It is part of the Transmission Control Protocol/Internet
Protocol (TCP/IP) protocol for network management. SNMP allow diverse network objects to participate in a network
management architecture. It enables network management systems to learn network problems by receiving traps or
change notices from network devices implementing SNMP.
SNTP
SNTP is an acronym for Simple Network Time Protocol, a network protocol for synchronizing the clocks of computer
systems. SNTP uses UDP (datagrams) as transport layer.
SPROUT
Stack Protocol using ROUting Technology. An advanced protocol for almost instantaneous discovery of topology
changes within a stack as well as election of a master switch. SPROUT also calculates parameters for setting up each
switch to perform shortest path forwarding within the stack.
STP
Spanning Tree Protocol is an OSI layer-2 protocol which ensures a loop free topology for any bridged LAN. The
original STP protocol is now obsoleted by RSTP.
Switch ID
Switch IDs (1-16) are used to uniquely identify the switches within a stack. The Switch ID of each switch is shown on
the display on the front of the switch and is used widely in the web pages as well as in the CLI commands.
T
Tag Priority
Tag Priority is a 3-bit field storing the priority level for the 802.1Q frame.
