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.

See “SimpleX signaling” on page 18.

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.
