Access Control List ACLs can limit network traffic and restrict access to certain users or (ACL) devices by checking each packet for certain IP or MAC (i.e., Layer 2) information. Address Resolution ARP converts between IP addresses and MAC (i.e., hardware) addresses. Protocol (ARP) ARP is used to locate the MAC address corresponding to a given IP address.
Page 239 Extensible EAPOL is a client authentication protocol used by this switch to verify Authentication the network access rights for any device that is plugged into the Protocol over LAN switch. A user name and password is requested by the switch, and (EAPOL) then passed to an authentication server (e.g., RADIUS) for verification.
Page 240 F: G PPENDIX LOSSARY Internet Control A network layer protocol that reports errors in processing IP packets. Message Protocol ICMP is also used by routers to feed back information about better (ICMP) routing choices. Internet Group A protocol through which hosts can register with their local router for Management multicast services.
Page 241 Multicast Switching A process whereby the switch filters incoming multicast frames for services for which no attached host has registered, or forwards them to all ports contained within the designated multicast VLAN group. Out-of-Band Management of the network from a station not attached to the Management network.

(RADIUS) Remote Monitoring RMON provides comprehensive network monitoring capabilities. It (RMON) eliminates the polling required in standard SNMP, and can set alarms on a variety of traffic conditions, including specific error types.
Page 243 IP-like services. UDP packets are delivered just like IP packets – connection-less datagrams that may be discarded before reaching their targets. UDP is useful when TCP would be too complex, too slow, or just unnecessary. Virtual LAN (VLAN) A Virtual LAN is a collection of network nodes that share the same collision domain regardless of their physical location or connection point in the network.
