Installation and User Guide: NMS Pro 325
one or more wireless network adapters as “belonging” to a common group. Some access points can
support multiple SSIDs, allowing for varying privileges and capabilities based on user roles.
Secure Sockets Layer (SSL)
A common protocol for message transmission security on the Internet. Existing as a program layer
between the Internet's Hypertext Transfer Protocol (HTTP) and Transport Control Protocol (TCP)
layers, SSL is a standard feature in Internet Explorer, Netscape, and most web server products.
Simple Mail Transfer Protocol (SMTP)
Protocol used to transfer email messages between email servers.
Simple Network Management Protocol (SNMP)
An efficient protocol for network management and device monitoring.
SNMP trap
A process that filers SNMP messages and saves or drops them, depending upon how the system is
configured.
Spanning Tree Protocol (STP)
A protocol that prevents bridging loops from forming due to incorrectly configured networks.
Station (STA)
An 802.11-capable device that supports only one 802.11 network interface, capable of establishing
a Basic Service Set 802.11 network (i.e., peer-to-peer network).
static IP address
A permanent IP address assigned to a node in a TCP/IP network.
subnet
A portion of a network, designated by a particular set of IP addresses. Provides a hierarchy for
addressing in LANs. Also called a subnetwork.
subnet mask
A TCP/IP addressing method for dividing IP-based networks into subgroups or subnets (compare
with maskbits). Each triplet of digits in an IP address consists of 8 bits. To specify using a subnet
mask, indicate the masked bits as an IP address. To specify the subnet in maskbits, count the
number of bits in the prefix. Example: subnet mask 255.255.255.0 is equivalent to 24 maskbits,
which is the total number of bits in the 255.255.255 prefix.
Temporal Key Integrity Protocol (TKIP)
Part of the IEEE 802.11i encryption standard, TKIP provides improvements to WEP encryption,
including per-packet key mixing, message integrity check, and a re-keying mechanism.
Traffic Class Identifier (TCID)
Part of the standard 802.11 frame header. The 3-bit TCID is used for mapping to class-of-service
values.
Transmission Control Protocol/Internet Protocol (TCP/IP)
One of the most commonly used communication protocols in modern networking. Addresses used
in TCP/IP usually consist of four triplets of digits, plus a subnet mask (for example, 192.168.25.3,
subnet 255.255.255.0).
Transport Layer Security (TLS)
A protocol that provides privacy protection for applications that communicate with each other and
their users on the Internet. TLS is a successor to the Secure Sockets Layer (SSL).
