Class 2 Fibre Channel
Service
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 Fibre Channel
Service
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.
Community A relationship between an SNMP agent and a set of SNMP managers
that defines authentication, access control, and proxy characteristics.
Community Name 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.
