Access Mode  Specifies the method by which user access is granted to the system.

Access Point  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 Profiles  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 List)  Access Control Lists are used to grant, deny, or limit access devices, features, or applications.

Auto-negotiation 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.

Bandwidth  The transmission capacity of a given device or network.

Bandwidth Assignments  Indicates the amount of bandwidth assigned to a specific application, user, and/or interface.

Glossary

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.

Bit  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.

Bridge  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 Domain  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 Size  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 (Committed Burst Size)  Indicates the maximum number of data bits transmitted within a specific time interval.

CIR (Committed Information 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.

Communities  Specifies a group of users which retain the same system access rights.
