Single mode The fiber-optic cabling standard for devices up to 10 km apart.
S-Link Service Facilities used between an N_Port and the fabric, or between two N_Ports, for login, sequence/
exchange management, and maintaining connections.
SLAP Switch Link Authentication Protocol.
SLP Service Location Protocol.
SMDS Switched Multimegabit Data Service. A good protocol for interconnecting LANs; however, SMDS has
less error-checking capability than Frame Relay.
SMF Single-mode fiber. See LWL.
SMI Storage Management Initiative. A broad-based initiative sponsored by the Storage Networking Industry
Association (SNIA) to standardize all aspects of storage management for multivendor storage
networking products.
SNMP Simple Network Management Protocol. SNMP is a standard method for monitoring and managing
network devices. Using SNMP components, you can program tools to view, browse, and manipulate
Brocade switch variables and set up enterprise-level management processes. Every Brocade switch
carries an SNMP agent and management information base (MIB). See also MIB.
SOF Start of frame. A group of ordered sets that marks the beginning of a frame and indicates the class of
service the frame will use.
software
enforced
zoning
This method of zoning is using when members are defined using both WWNs and domain, port.
Software-enforced zoning prevents hosts from discovering unauthorized target devices, while
hardware-enforced zoning prevents a host from accessing a device it is not authorized to access. See
also hardware-enforced zoning.
SoIP SCSI-over-IP.
SONET Synchronous optical network. A standard for optical networks that provides building blocks and
flexible payload mappings.
special
character
A 10-bit character that does not have a corresponding 8-bit value but is still considered valid. The
special character is used to indicate that a particular transmission word is an ordered set. This is the only
type of character to have five 1s or 0s in a row.
SSH Secure shell. Used starting in Fabric OS v4.1.x to support encrypted telnet sessions to the switch. SSH
encrypts all messages, including the client sending the password at login.
SSL Secure sockets layer.
Standard
Translative
Mode
Allows public devices to communicate with private devices that are directly connected to the fabric.
