Dynamic Host
Configuration
Protocol
A protocol that provides information to dynamically assign IP addresses and other configuration
parameters to network hosts based on policies.
E
Encapsulated
Remote Port
Monitoring
(ERPM)
A protocol that encapsulates traffic from the source port and forwards it to the destination port in
another switch.
Enhanced
Transmission
Selection (ETS)
A transmission selection algorithm that increases preferred traffic class throughput during network
congestion.
Equal Cost Multi-
Path (ECMP)
A network routing strategy that provides next-hop packet forwarding to a single destination over multiple
best paths.
EXEC mode A mode that provides access to monitoring and troubleshooting commands.
Expansion port
(E_Port)
A port that connects two fibre channel switches to form a multiswitch SAN fabric.
Explicit
Congestion
Notification
(ECN)
An extension to the Internet Protocol and Transmission Control Protocol that allows notification of
congestion without any drop in packets.
Extensible
Authentication
Protocol (EAP)
A protocol that provides device credentials to an authentication server, typically a remote authentication
dial-in service (RADIUS), using an intermediary network access device.
F
Fabric Shortest
Path First
(FSPF)
A standard path selection protocol used by Fibre Channel fabrics.
Far-End Failure
Detection (FEFD)
A protocol that detects remote data link errors in a network.
FCoE
Initialization
Protocol (FIP)
A protocol that establishes Fibre Channel connectivity with Ethernet ports.
Fiber Channel
over Ethernet
(FCoE)
A storage protocol that enables Fiber Channel communications to run over Ethernet.
Fibre Channel
Fabric Port
(F_Port)
A switch port that connects the Fibre Channel fabric to a host.
Fibre Channel
Zoning (FC
zoning)
A process that partitions a Fibre Channel fabric into subsets to restrict unnecessary interactions, improve
security, and manage the fabric more effectively.
FIP Snooping
Bridge (FSB)
A mode that implements security characteristics to admit valid FCoE traffic in the Ethernet networks.
First Hop Router
(FHR)
A router that is directly connected to the multicast source. The FHR is responsible for the Protocol
Independent Multicast (PIM) register process.
Force-
unauthorized
An unauthorized state in which a device connected to a port is not allowed to communicate on the
network without using the authentication process.
