SNMP
See “Simple Network Management Protocol” on page 18.
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 multi-looped, 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.
SRAM
Static Random Access Memory.
STP
Spanning Tree Protocol. See “802.1D” on page 1 for more information.
stub area
OSPF area that carries a default route, intra-area routes, and interarea routes, but does not carry external
routes. Virtual links cannot be configured across a stub area, and they cannot contain an ASBR. Compare
with non-stub area. See also OSPF. (Cisco Systems Inc.)
Subnet Mask
Combined with the IP address, the IP Subnet Mask allows a device to know which other addresses are local
to it, and which must be reached through a gateway or router.
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.
SX
See “SimpleX signaling” on page 18.
T
Telnet
A character-based UNIX application that enables users with a Telnet server account to log on to a UNIX
computer and utilize its resources.
