Simple Network Management Protocol (SNMP) trap

An SNMP protocol utility that sends out an alarm in an identified community notifying members of the community that some network activity differs from the established threshold, as defined by the administrator.

Simple Server Redundancy Protocol (SSRP)

A Cisco protocol that provides redundancy for all LANE server components. Single Attached Station (SAS)

A FDDI device that has only a single connection to a single DAC. smart bridge

A bridge that builds its own bridging address table. No manual configuration or intervention is required. Also known as a learning bridge.

socket

A logical interprocess communications mechanism through which a program communicates with another program or with a network.

socket identifier

An eight−bit number used to identify the socket. Developers and designers of services and protocols usually assign socket identifiers. Also known as a socket number.

source address

The address of the host who sent the frame. It is contained in the frame so the destination node knows who sent the data.

Source Route Bridging (SRB)

A type of bridging used to segment Token Ring networks. It requires all rings and bridges to have a unique number.

Source Route Switching (SRS)

A type of bridging that combines SRB and SRT, developed to allow more physical rings on the network. It allows for growing bandwidth needs while preserving the benefits of SRB.

Source Route Translational Bridging (SR/TRB)

A type of bridging that bridges a Token Ring segment to another physical media type such as Ethernet or FDDI. It is transparent to the source and destination interfaces.

Source Route Transparent Bridging (SRT)

A type of bridging that combines SRB and TB. Using SRT, the bridge places a RIF into a frame traveling from the TB to the SRB side. It then strips out the RIF when the frame travels from the SRB port to the TB port.

Source Service Access Point (SSAP)

A one−byte field in the frame that combines with the SAP to tell the receiving host the identity of the source or sending host.

Spanning−Tree Algorithm (STA)

Defined by IEEE 802.1 as part of the Spanning−Tree Protocol (STP) to eliminate loops in an internetwork with multiple paths. The STA is responsible for performing STP topology recalculations when a switch is powered up and when a topology change occurs.

Spanning−Tree Protocol (STP)

Protocol developed to eliminate the loops caused by the multiple paths in an internetwork. It’s defined by IEEE 802.1. STP communicates topology changes from switch to switch with the use of BPDUs.

Standby Route Processor

The router standing by in an HSRP Standby Group, waiting to take over in the event the active route processor fails.

static IP addresses

IP addresses that are assigned to each network device individually; often referred to as hard−coded. static VLAN port

A port on a switch manually assigned a VLAN number. Any node or interface connected to the port automatically becomes a member of the assigned VLAN.

static window

A mechanism used in flow control that prevents the sender of data from overwhelming the receiver. Only a set amount of data can be buffered in a static window.

station IPX address
