Glossary

Authentication, authorization, and accounting. A system to control which 
computer resources specific users can access and to keep track of the activity of 
specific users over the network.

Area border router. In OSPF, an ABR has interfaces in multiple areas, and it is 
responsible for exchanging summary advertisements with other ABRs.

Access Control List. ACLs are a mechanism for filtering packets at the hardware 
level. Packets can be classified by characteristics such as the source or 
destination MAC, IP addresses, IP type, or QoS queue. Once classified, the 
packets can be forwarded, counted, queued, or dropped. In XCM8800 software, 
you configure ACLs by creating a file, called a policy file (with a .pol file 
extension). The system parses the policy file and loads the ACL into the 
hardware.

In RSTP, the alternate port supplies an alternate path to the root bridge and the 
root port.

Access point. In wireless technology, access points are the devices that connect 
to the regular wired network and forward and receive the radio signals that 
transmit wireless data.

In OSPF, an area is a logical set of segments connected by routers. The 
topology within an area is hidden from the rest of the AS.

Address Resolution Protocol. ARP is part of the TCP/IP suite used to 
dynamically associate a device’s physical address (MAC address) with its logical 
address (IP address). The system broadcasts an ARP request, containing the IP 
address, and the device with that IP address sends back its MAC address so 
that traffic can be transmitted.
