Glossary
Preferred Domain ID Domain ID that a switch is assigned by the principal switch in a
switched fabric. The preferred domain ID becomes the active
domain ID except when configured otherwise by the user.
Principal Switch In a multiswitch fabric, the switch that allocates domain IDs to
itself and to all other switches in the fabric. There is always one
principal switch in a fabric. If a switch is not connected to any
other switches, it acts as its own principal switch.
Product
(1) Connectivity Product, a generic name for a switch, director, or any
other Fibre Channel product. (2) Managed Product, a generic
hardware product that can be managed by the Product Manager (a
Connectrix switch is a managed product). Note distinction from the
definition for Device.
Product Manager A software component of the Connectrix Management software, such
as a Connectrix switch Product Manager, that implements the
management user interface for a specific product. When a Product
instance is opened from the Connectrix Management software
Product View, the corresponding Product Manager is invoked.
Product Name A user configurable identifier assigned to a Managed Product.
Typically, this name is stored on the product itself. For a Connectrix
switch, the Product Name can also be accessed by an SNMP Manager
as the System Name. The Product Name should align with the host
name component of a Network Address.
Product View The top-level display in the Connectrix Management software user
interface that displays icons of Managed Products.
Protocol
(1) A set of semantic and syntactic rules that determines the behavior
of functional units in achieving communication. (2) A specification
for the format and relative timing of information exchanged between
communicating parties.
R
R_A_TOV See Resource Allocation Time Out Value.
Resource Allocation Is used to time out operations that depend on the maximum possible
Time Out Value time that a frame could be delayed in a fabric and still be delivered.
The resource allocation time out value of (R_A_TOV) can be set
within a range of two-tenths of a second to 120 seconds using the
Connectrix switch Product Manager.
