ECMP 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.
edge ports In STP, edge ports connect to non-STP devices such as routers, endstations,
and other hosts.
EEPROM 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.
EGP 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.
ELRP Loop Recovery Protocol. ELRP is an NETGEAR-proprietary protocol that allows
you to detect Layer
2 loops.
EMISTP 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.
EMS 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.
encapsulation mode 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 EPICenter is an NETGEAR-proprietary graphical user interface (GUI) network
management system.
Ethernet 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.
