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.
Note
Consult your network administrator for further assistance with SNMP.
1 If you are not already in the ExpressNAV
interface, type the IP address of your FibreBridge in a standard browser as found in
Using ExpressNAV on page 25, click Enter
Here, type in your user name and password, and click OK.
2 On the left hand menu, click Remote Mgt.
3The Remote Management page appears.
Click on the enabled radio button next to the SNMP heading.
4Click on the appropriate radio button for SNMP Traps, SNMP Extended Traps and Auto Log Sense.
•SNMP Traps and SNMP Extended Traps are notifications for SNMP functions such as device transition and device error.
•Auto Log Sense controls whether current data from log pages in a SCSI target device is available automatically.
5Enter the IP addresses of the those who should receive messages (SNMP trap recipients) in the text boxes on the left.
6Select the type of message you wish each recipient to receive from the drop down box next to each address.
7Click Submit.
