A product feature that allows the Connectrix service processor to
automatically dial out to a support center and report system
problems. The support center server accepts calls from the Connectrix
service processor, logs reported events, and can notify one or more
support center representatives. Telephone numbers and other
information are configured through the Windows NT dial-up
networking application. The Call Home function can be enabled and
disabled through the Product Manager.
Point-to-point link that transports data from one point to the
other.
In Class 2 service, the fabric and destination N_Ports provide
Service connectionless service with notification of delivery or nondelivery
between the two N_Ports.
Class 3 service provides a connectionless service without notification
Service of delivery between N_Ports. (This is also known as datagram
service.) The transmission and routing of Class 3 frames is the same
as for Class 2 frames.
A relationship between an SNMP agent and a set of SNMP managers
that defines authentication, access control, and proxy characteristics.
A name that represents an SNMP community that the agent software
recognizes as a valid source for SNMP requests. An SNMP
management program that sends an SNMP request to an agent
program must identify the request with a community name that the
agent recognizes or the agent discards the message as an
authentication failure. The agent counts these failures and reports the
count to the manager program upon request, or sends an
authentication failure trap message to the manager program.
Information that specifies which management objects are
available to what management domain or SNMP community
name.
Nondedicated link. Typically used to describe a link between
nodes that allows the switch to forward Class 2 or Class 3 frames
as resources (ports) allow. Contrast with the dedicated bandwidth
that is required in a Class 1 Fibre Channel Service point-to-point
link.
