Access Mode -
Specifies the method by which user access
is granted to the system .
Access Pont -
A device that allows wireless-equipped
computers and other devices to communicate with a
wired network . Also used to expand the range of a wireless
network .
Access Profles -
Allows network managers to define
profiles and rules for accessing the device . Access to
management functions can be limited to user groups,
which are defined by the following criteria:
Ingress interfaces
Source IP address and/or Source IP subnets .
ACE -
Filters in Access Control Lists (ACL) that determine
which network traffic is forwarded . An ACE is based on the
following criteria:
Protocol
Protocol ID
Source Port
Destination Port
Wildcard Mask
Source IP Address
Destination IP Address
ACL (Access Control Lst) -
Access Control Lists are
used to grant, deny, or limit access devices, features, or
applications .
Auto-negotaton
- Allows 10/100 Mbps or 10/100/1000
Mbps Ethernet ports to automatically establish the optimal
duplex mode, flow control, and speed .
Back Pressure -
A mechanism used with Half Duplex
mode that enables a port not to receive a message .
Bandwdth -
The transmission capacity of a given device
or network .
Bandwdth Assgnments -
Indicates the amount of
bandwidth assigned to a specific application, user, and/or
interface .

Baud -
Indicates the number of signaling elements
transmitted each second .
Best Effort -
Indicates that traffic is assigned to the lowest
priority queue, and packet delivery is not guaranteed .
Bt -
A binary digit .
Boot -
To start a device and cause it to start executing
instructions .
Browser -
An application program that provides a way to
look at and interact with all the information on the World
Wide Web .
Brdge -
A device that connect two networks . Bridges are
hardware specific, however they are protocol independent .
Bridges operate at Layer 1 and Layer 2 levels .
Broadcast Doman -
Devices sets that receive broadcast
frames originating from any device within a designated
set . Routers bind Broadcast domains, because routers do
not forward broadcast frames .
Broadcast Storm -
An excessive amount of broadcast
messages simultaneously transmitted across a network
by a single port . Forwarded message responses are
heaped onto the network, overloading network resources
or causing the network to time out .
Burst -
A packet transmission at faster than normal rates .
Bursts are limited in time and only occur under specific
conditions .
Burst Sze -
Indicates the burst size transmitted at a faster
than normal rate .
Byte -
A unit of data that is usually eight bits long
Cable Modem -
A device that connects a computer to the
cable television network, which in turn connects to the
Internet .
CBS (Commtted Burst Sze) -
Indicates the maximum
number of data bits transmitted within a specific time
interval .
CIR (Commtted Informaton Rate) -
The data rate is
averaged over a minimum time increment .
Class Maps -
An aspect of Quality of Service system that is
comprised of an IP ACL and/or a MAC ACL . Class maps are
configured to match packet criteria, and are matched to
packets in a first-fit fashion .
Combo Ports -
A single logical port with two physical
connections, including an RJ-45 connection and a SFP
connection .
Communtes -
Specifies a group of users which retain the
same system access rights .
