SNMP-based monitoring
The Simple Network Management Protocol
(SNMP) facilitates the exchange of management
information between network devices.
An agent resides in the FibreBridge which takes
information from the FibreBridge and translates it
into a form compatible with SNMP. If certain
conditions arise, the agent sends asynchronous
notifications (traps) to a client.
1 If you have not already, open an ExpressNAV
session. For instructions, refer to
Open an
ExpressNAV session on page 27.

data from log pages in a SCSI target device
is available automatically.
