Glossary
SNMP community name
The name assigned to a given SNMP community. Queries from an SNMP management station
to a device running an SNMP agent will only elicit a response if those queries are addressed
with the correct SNMP community name.
storage area network (SAN)
A high-performance data communications environment that interconnects computing and
storage resources so that the resources can be effectively shared and consolidated.
subnet mask
Used by a computer to determine whether another computer with which it needs to
communicate is located on a local or remote network. The network mask depends upon the
class of networks to which the computer is connecting. The mask indicates which digits to
look at in a longer network address and allows the router to avoid handling the entire address.
Switch
An intelligent but nonredundant, low-port count Fibre Channel switching device providing
any-to-any port connectivity between nodes (end devices) in a switched fabric. Switches send
data frames between nodes in accordance with the address information present in the frame
headers of those transmissions.
switchover
Changing a backup FRU to the active state, and the active FRU to the backup state.
Switch priority
Value configured into each Switch in a fabric that determines its relative likelihood of
becoming the fabric's principal Switch.
TCP/IP
See transmission control protocol/internet protocol.
topology
Logical and/or physical arrangement of stations on a network.
transmission control protocol/internet protocol (TCP/IP)
A suite of communication protocols used to connect host systems to the Internet. See also
network address.
trap
Unsolicited notification of an event originating from an SNMP managed device and directed to
an SNMP network management station.
trap host
SNMP management workstation that is configured to receive traps.
