Appendix D: Glossary

This glossary contains some basic networking terms you may come across when using this product. For more
advanced terms, see the complete Linksys glossary at http://www.linksys.com/glossary.

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 (A

ccess

ontrol

ist

)

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.
