N (Continued) netlogin netmask NLRI node Node Manager NSSA O odometer option 82 OSI NETGEAR 8800 User Manual Network login provides extra security to the network by assigning addresses only to those users who are properly authenticated. You can use web-based, MAC-based, or IEEE 802.1x-based authentication with network login. The two modes of operation are campus mode and ISP mode. A netmask is a string of 0s and 1s that mask, or screen out, the network part of an IP address, so that only the host computer part of the address remains. Network layer reachability information. In BGP, the system sends routing update messages containing NLRI to describe a route and how to get there. A BGP update message carries one or more NLRI prefixes and the attributes of a route for each NLRI prefix; the route attributes include a BGP next hop gateway address, community values, and other information. In the NETGEAR implementation, a node is a CPU that runs the management application on the switch. Each MSM on modular switches installed in the chassis is a node. In general networking terms, a node is a device on the network. The Node Manager performs the process of node election, which selects the master, or primary, MSM when you have two MSMS installed in the modular chassis. The Node Manager is useful for system redundancy. Not-so-stubby area. In OSPF, NSSA is a stub area, which is connected to only one other area, with additional capabilities: • External routes originating from an ASBR connected to the NSSA can be advertised within the NSSA. • External routes originating from the NSSA can be propagated to other areas. In the NETGEAR implementation, each field replaceable component contains a system odometer counter in EEPROM. On modular switches, using the CLI, you can display how long each following individual component has been in service: • chassis • MSMs • I/O modules • power controllers On stand-alone switches, you display the days of service for the switch. This is a security feature that you configure as part of BOOTP/DHCP. Option 82 allows a server to bind the client's port, IP address, and MAC number for subscriber identification. Open Systems Interconnection. OSI is the international standard computer network architecture known for its 7-layer reference model. 936 | Appendix E. Glossary
