active zone set The zone set that defines the current zoning for the fabric.
active firmware The firmware image on the switch that is in use.
Activity LED A port LED that indicates when frames are entering or leaving the port.

Physical Address
(AL_PA)
A unique one-byte value assigned during loop initialization to each NL_Port on a loop.
Auto Save Zoning parameter that determines whether changes to the active zone set that a switch receives
from other switches in the fabric is saved to permanent memory on that switch.
BootP A type of network server.
buffer credit A measure of port buffer capacity equal to one frame.
CIM Common Interface Model
class 2 service A service that multiplexes frames at frame boundaries to or from one or more N_Ports with
acknowledgment provided.
class 3 service A service that multiplexes frames at frame boundaries to or from one or more N_Ports without
acknowledgment.
configured zone sets The zone sets stored on a switch, excluding the active zone set.
DHCP Dynamic Host Configuration Protocol
Default Visibility Zoning parameter that determines the level of communication among ports/devices when there
is no active zone set.
domain ID User-defined number that identifies the switch in the fabric.
event log Log of messages describing events that occur in the fabric.
