Community (SNMP)

An SNMP community is a relationship
between an SNMP agent and a set of
SNMP managers that defines
authentication, access control, and proxy
characteristics.

Credit

Credit, applied to a Switch, is a numeric
value that represents the maximum
number of receive buffers provided by an
F_Port or FL_Port to its attached N_Port or
NL_Port respectively such that the N_Port
or NL_Port may transmit frames without
over-running the F_Port or NL_Port.

Class 2

In Class-2 service, the Fabric and
destination N_Port provide connectionless
service with notification of delivery or
nondelivery between the two N_Ports.

Class 3

Class-3 service provides a connectionless
service without notification of delivery
between N_Ports. The transmission and
routing of Class-3 frames is the same as
for Class-2 frames.

Domain_ID

The domain number uniquely identifies the
Switch in a Fabric. This Switch domain ID
is normally automatically assigned by the
Switch and may be any value between 0
and 31. The default domain ID number
may also be assigned manually.
