Isolated E_Port

ISL is online but not operational between
Switches because of overlapping domain
ID or nonidentical parameters such as
E_O_TOVs.

Simple Network Management Protocol
(SNMP)

SNMP is a TCP/IP protocol that generally
uses the User Datagram Protocol (UDP) to
exchange messages between a
management information base and a
management client residing on a network.
Since SNMP does not rely on the
underlying communication protocols, it
can be made available over other
protocols, such as UDP/IP.

SNMPv1

The original standard for SNMP is now
referred to as SNMPv1.

Trap (SNMP)

A trap is a mechanism for SNMP agents to
notify the SNMP management station of
significant events.

Unicast

Unicast routing provides one or more
optimal path(s) between any of two
Switches that make up the Fabric. This is
for a single copy of the data to be sent to
designated destinations.

Worldwide Name (WWN)

A WWN uniquely identifies a Switch on
local and global networks.
