Spanning Tree Protocol (STP) The Spanning Tree Protocol (STP) can be used to create redundant
networks (“hot standby”) and to prevent loops. If enabled, spanning tree
prevents loops by disabling redundant links. If a link fails, it can
automatically enable a backup link.
SSH A security protocol for logging into a remote server. SSH provides an
encrypted session for transferring files and executing server programs.
SSL Secure Socket Layer is a commonly used encryption scheme used by many
online retail and banking sites to protect the financial integrity of
transactions.
SSID A Service Set Identifier (also referred to as a network name) is a common
name that identifies a wireless network. The identifier is attached to the
wireless local area network (WLAN) and acts as an identifier when a device
tries to connect to the system. A device will not be permitted to join the
network unless it can provide the unique SSID. An SSID can be broadcast
by the network router, allowing devices to detect it as an available
network. An SSID does not supply security to the network
STP Frames The data frames exchanged in an STP network topology are called as the
STP Frames, BPDU frames being one of them.
Subnet Mask A subnet mask is a bit mask that defines which part of an IP address is
used for the network part and which part for a host (computer) number.
A subnet mask is like an IP address represented by four numbers in the
range 0 - 255 separated by dots. When the IP address 172.17.23.14 has a
subnet mask of 255.255.255.0, the network part is 172.17.23 and the
host number is 14. See also IP address.
Syslog Server Syslog Server receives, logs, displays, and forwards syslog messages from
network devices like routers.
T
Tagged Frames When a frame enters the VLAN-aware area of the network, a tag is added
to represent the VLAN membership of the frame's port or the
port/protocol combination. These are called Tagged Frames.
TCP / IP The TCP/IP internet-suite protocol describes a set of general design
guidelines and implementations of specific networking protocols to
enable computers to communicate over a network. TCP/IP provides
end-to-end connectivity specifying how data should be formatted,
addressed, transmitted, routed and received at the destination.
Telnet Telnet is a network protocol used on the Internet or local area networks to
access the command-line interface, on a remote host. Most network
equipment and operating systems with a TCP/IP stack support a Telnet
service for remote configuration.
Topology Topology is the physical layout of network components (cable, wireless
clients, gateways, hubs, and so on).
