Glossary-3
CLI Command line interface. An interface that depends entirely on the use of commands, such as through
telnet or SNMP, and does not involve a GUI.
client An entity that, using its common transport (CT), makes requests of a server.
community
(SNMP)
A relationship between a group of SNMP managers and an SNMP agent, in which authentication,
access control, and proxy characteristics are defined. See also SNMP.
compact flash Flash (temporary) memory that is used in a manner similar to hard disk storage. It is connected to a
bridging component that connects to the PCI bus of the processor. Not visible within the processor's
memory space.
configuration (1) A set of parameters that can be modified to fine-tune the operation of a switch. Use the configshow
command to view the current configuration of your switch.
(2) In Brocade Zoning, a zoning element that contains a set of zones. The Configuration is the highest-
level zoning element and is used to enable or disable a set of zones on the fabric. See also zone
configuration.
congestion The realization of the potential of oversubscription. A congested link is one on which multiple devices
are contending for bandwidth.
core PID Core switch port identifier. The core PID must be set for v3.1 and earlier switches included in a fabric of
v4.1 switches. This parameter is located in the configure command of firmware versions v3.1 and
earlier. All v4.1 switches and above use the core PID format by default; this parameter is not present in
the configure command for these switches.
CSCN Common services connection framework.
D
defined zone
configuration
The set of all zone objects defined in the fabric. Can include multiple zone configurations. See also
enabled zone configuration, zone configuration.
deskew Related to the Brocade Trunking feature. The time difference between traffic traveling over each ISL
other than the shortest ISL in the group and traffic traveling over that shortest ISL. The deskew number
corresponds to nanoseconds divided by 10. The firmware automatically sets the minimum deskew value
of the shortest ISL to 15.
DH-CHAP Diffie-Hellman Challenge-Handshake Authentication Protocol. An implementation of CHAP using
Diffie-Hellman encryption. See also CHAP.
digital
certificate
An electronic document issued by a CA (certificate authority) to an entity, containing the public key and
identity of the entity. Entities in a secure fabric are authenticated based on these certificates. See also
authentication, public key.
director A Brocade SilkWorm 12000, or 24000 switch.
domain ID A unique identifier for all switches in a fabric, used in routing frames. Usually automatically assigned
by the principal switch but can be assigned manually. The domain ID for a Brocade SilkWorm switch
can be any integer between between 1 and 239.
