DHCP Option 82
A relay option for sending information about the requesting client (or an intermediate
relay agent) in the DHCP request packets forwarded by the switch and in reply
packets sent back from the DHCP server. This information can be used by DHCP
servers to assign fixed IP addresses, or set other services or policies for clients.
DHCP Snooping
A technique used to enhance network security by snooping on DHCP server
messages to track the physical location of hosts, ensure that hosts only use the IP
addresses assigned to them, and ensure that only authorized DHCP servers are
accessible.
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.
File Transfer Protocol
(FTP)
A TCP/IP protocol commonly used for software downloads.
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.
(GARP)
GARP is a protocol that can be used by endstations and switches to register and
propagate multicast group membership information in a switched environment so
that multicast data frames are propagated only to those parts of a switched LAN
containing registered endstations. Formerly called Group Address Registration
Protocol.
Generic Multicast Registration Protocol
(GMRP)
GMRP allows network devices to register end stations with multicast groups. GMRP
requires that any participating network devices or end stations comply with the IEEE
802.1p standard.
(GARP)
See Generic Attribute Registration Protocol.
