TACACS+ (Terminal Access Controller Access Control System Plus) - Proprietary Cisco enhancement to Terminal
Access Controller Access Control System (TACACS). Provides additional support for authentication, authorization,
and accounting.
TCP (Transmission Control Protocol) - A network protocol for transmitting data that requires acknowledgement
from the recipient of data sent.
TCP/IP (Transmission Control Protocol/Internet Protocol) - A set of instructions PCs use to communicate over a
network.
Telnet - A user command and TCP/IP protocol used for accessing remote PCs.
TFTP (Trivial File Transfer Protocol) - A version of the TCP/IP FTP protocol that has no directory or password
capability.
Throughput - The amount of data moved successfully from one node to another in a given time period.
Trunking - Link Aggregation. Optimizes port usage by linking a group of ports together to form a single trunk
(aggregated groups).
TX Rate - Transmission Rate.
UDP (User Data Protocol) - Communication protocol that transmits packets but does not guarantee their delivery.
Upgrade - To replace existing software or firmware with a newer version.
Upload - To transmit a file over a network.
URL (Uniform Resource Locator) - The address of a file located on the Internet.
VLAN (Virtual Local Area Networks) - Logical subgroups that constitute a Local Area Network (LAN). This is done
in software rather than defining a hardware solution.
WAN (Wide Area Network) - Networks that cover a large geographical area.
Wildcard Mask - Specifies which IP address bits are used, and which bits are ignored. A wild card mask of
255.255.255.255 indicates that no bit is important. A wildcard of 0.0.0.0 indicates that all the bits are important.
For example, if the destination IP address is 149.36.184.198 and the wildcard mask is 255.36.184.00, the first
two bits of the IP address are used, while the last two bits are ignored.
