Appendix E: Glossary Access Control List (ACL) ACLs can limit network traffic and restrict access to certain users or devices by checking each packet for certain IP or MAC (i.e., Layer 2) information. Boot Protocol (BOOTP) BOOTP is used to provide bootup information for network devices, including IP address information, the address of the TFTP server that contains the devices system files, and the name of the boot file. Class of Service (CoS) CoS is supported by prioritizing packets based on the required level of service, and then placing them in the appropriate output queue. Data is transmitted from the queues using weighted round-robin service to enforce priority service and prevent blockage of lower-level queues. Priority may be set according to the port default, the packet's priority bit (in the VLAN tag), TCP/UDP port number, or DSCP priority bit. Differentiated Services Code Point (DSCP) DSCP uses a six-bit tag to provide for up to 64 different forwarding behaviors. Based on network policies, different kinds of traffic can be marked for different kinds of forwarding. The DSCP bits are mapped to the Class of Service categories, and then into the output queues. Domain Name Service (DNS) A system used for translating host names for network nodes into IP addresses. Dynamic Host Control Protocol (DHCP) Provides a framework for passing configuration information to hosts on a TCP/IP network. DHCP is based on the Bootstrap Protocol (BOOTP), adding the capability of automatic allocation of reusable network addresses and additional configuration options. Extensible Authentication Protocol over LAN (EAPOL) EAPOL is a client authentication protocol used by this switch to verify the network access rights for any device that is plugged into the switch. A user name and password is requested by the switch, and then passed to an authentication server (e.g., RADIUS) for verification. EAPOL is implemented as part of the IEEE 802.1X Port Authentication standard. GARP VLAN Registration Protocol (GVRP) Defines a way for switches to exchange VLAN information in order to register necessary VLAN members on ports along the Spanning Tree so that VLANs defined in each switch can work automatically over a Spanning Tree network. Generic Attribute Registration Protocol (GARP) The GARP provides a generic attribute dissemination capability that is used by participants in GARP Applications (GARP Participants) to register and de-register attribute values with other GARP Participants within a Bridged LAN. The definition of the attribute types, the values that they can carry, and the semantics that are associated with those values when registered, are specific to the operation of the GARP Application concerned.

Appendix E: Glossary

Access Control List (ACL)

ACLs can limit network traffic and restrict access to certain users or devices by checking each

packet for certain IP or MAC (i.e., Layer 2) information.

Boot Protocol (BOOTP)

BOOTP is used to provide bootup information for network devices, including IP address

information, the address of the TFTP server that contains the devices system files, and the name

of the boot file.

Class of Service (CoS)

CoS is supported by prioritizing packets based on the required level of service, and then placing

them in the appropriate output queue. Data is transmitted from the queues using weighted

round-robin service to enforce priority service and prevent blockage of lower-level queues. Priority

may be set according to the port default, the packet’s priority bit (in the VLAN tag), TCP/UDP port

number, or DSCP priority bit.

Differentiated Services Code Point (DSCP)

DSCP uses a six-bit tag to provide for up to 64 different forwarding behaviors. Based on network

policies, different kinds of traffic can be marked for different kinds of forwarding. The DSCP bits

are mapped to the Class of Service categories, and then into the output queues.

Domain Name Service (DNS)

A system used for translating host names for network nodes into IP addresses.

Dynamic Host Control Protocol (DHCP)

Provides a framework for passing configuration information to hosts on a TCP/IP network. DHCP

is based on the Bootstrap Protocol (BOOTP), adding the capability of automatic allocation of

reusable network addresses and additional configuration options.

Extensible Authentication Protocol over LAN (EAPOL)

EAPOL is a client authentication protocol used by this switch to verify the network access rights for

any device that is plugged into the switch. A user name and password is requested by the switch,

and then passed to an authentication server (e.g., RADIUS) for verification. EAPOL is

implemented as part of the IEEE 802.1X Port Authentication standard.

GARP VLAN Registration Protocol (GVRP)

Defines a way for switches to exchange VLAN information in order to register necessary VLAN

members on ports along the Spanning Tree so that VLANs defined in each switch can work

automatically over a Spanning Tree network.

Generic Attribute Registration Protocol (GARP)

The GARP provides a generic attribute dissemination capability that is used by participants in

GARP Applications (GARP Participants) to register and de-register attribute values with other

GARP Participants within a Bridged LAN. The definition of the attribute types, the values that they

can carry, and the semantics that are associated with those values when registered, are specific to

the operation of the GARP Application concerned.
