NETGEAR 8800 User Manual E (Continued) ECMP edge ports EEPROM EGP ELRP EMISTP EMS encapsulation mode EPICenter Ethernet Equal Cost Multi Paths. This routing algorithm distributes network traffic across multiple high-bandwidth OSPF, BGP, and static routes to increase performance. The NETGEAR implementation supports multiple equal cost paths between points and divides traffic evenly among the available paths. In STP, edge ports connect to non-STP devices such as routers, endstations, and other hosts. Electrically erasable programmable read-only memory. EEPROM is a memory that can be electronically programmed and erased but does not require a power source to retain data. Exterior Gateway Protocol. EGP is an Internet routing protocol for exchanging reachability information between routers in different ASs. BGP is a more recent protocol that accomplishes this task. Loop Recovery Protocol. ELRP is an NETGEAR-proprietary protocol that allows you to detect Layer 2 loops. Extreme Multiple Instance Spanning Tree Protocol. This NETGEAR-proprietary protocol uses a unique encapsulation method for STP messages that allows a physical port to belong to multiple STPDs. Event Management System. This NETGEAR-proprietary system saves, displays, and filters events, which are defined as any occurrences on a switch that generate a log message or require action. Using STP, you can configure ports within an STPD to accept specific BPDU encapsulations. The three encapsulation modes are: • 802.1D-This mode is used for backward compatibility with previous STP versions and for compatibility with third-party switches using IEEE standard 802.1D. • EMISTP-Multiple Instance Spanning Tree Protocol mode is an extension of STP that allows a physical port to belong to multiple STPDs by assigning the port to multiple VLANs. • PVST+-This mode implements PVST+ in compatibility with third-party switches running this version of STP. EPICenter is an NETGEAR-proprietary graphical user interface (GUI) network management system. This is the IEEE 802.3 networking standard that uses carrier sense multiple access with collision detection (CSMA/CD). An Ethernet device that wants to transmit first checks the channel for a carrier, and if no carrier is sensed within a period of time, the device transmits. If two devices transmit simultaneously, a collision occurs. This collision is detected by all transmitting devices, which subsequently delay their retransmissions for a random period. Ethernet runs at speeds from 10 Mbps to 10 Gbps on full duplex. 928 | Appendix E. Glossary
