AAA Authentication, authorization, and accounting, pronounced triple A.
access list A list kept by routers to control access to or from the router for a number of
services (for example, to prevent packets with a certain IP address from
leaving a particular interface on the router).
AIM Asynchronous interface module. Type of network module.
appliance Alternate term for network module.
ARP Address Resolution Protocol. Internet protocol used to map an IP address to
a MAC address.
blade Alternate term for network module.
boothelper See helper.
bootloader A small set of system software that runs when the system first powers up. It
loads the operating system (from the disk, network, external flash, or
external USB flash), which loads and runs the NME-NAM-120S application.
The bootloader might optionally load and run the boothelper.
CEF Cisco Express Forwarding
DSMON Differentiated Services Monitoring
Flooding Traffic passing technique used by switches and bridges in which traffic
received on an interface is sent out all the interfaces of that device except the
interface on which the information was received originally.
FTP File Transfer Protocol. Application protocol, part of the TCP/IP protocol
stack, used for transferring files between network nodes.
GRE Generic routing encapsulation. Tunneling protocol developed by Cisco that
can encapsulate a wide variety of protocol packet types inside IP tunnels,
creating a virtual point-to-point link to Cisco routers at remote points over
an IP internetwork. By connecting multiprotocol subnetworks in a
single-protocol backbone environment, IP tunneling using GRE allows
network expansion across a single-protocol backbone environment.
GUI Graphical user interface. A user environment that uses pictorial as well as
textual representations of the input and the output of applications and the
hierarchical or other data structure in which information is stored. Such
conventions as buttons, icons, and windows are typical, and many actions are
performed using a pointing device (such as a mouse). Microsoft Windows
and the Apple Macintosh are prominent examples of platforms using a GUI.
helper
(previously known as
boothelper)
A small subset of the system software that runs on the module. It boots the
module from the network and assists in software installation and upgrades,
disaster recovery, and other operations when the module cannot access its
software.
IP Multicast Routing technique that allows IP traffic to be propagated from one source to
a number of destinations or from many sources to many destinations. Rather
than sending one packet to each destination, one packet is sent to a multicast
group identified by a single IP destination group address.
