Device Manager communicates with the Using the OPTera Metro 1200 Ethernet Service Module using Simple Network Management Protocol (SNMP). The software is shipped with default values set for important communication parameters, such as the polling interval, timeout, and retry count. You may want to set the parameters before you open a device to manage.
To set the Device Manager properties:
| The Properties dialog box opens. |
The following table describes the Properties dialog box items.
Polling
Status Interval
Interval at which status information is gathered (default is 20 seconds).
(If Traps, Status Interval: )
Interval at which statistics and status information are gathered when traps are enabled. The default is 60.
Hotswap Detect Every
The number of status intervals between Device Manager polls for module information. The default is 1 interval.
Enable
Enables (true) or disables (false) periodic polling of the device for updated status. If polling is disabled, the chassis status is updated only when you click Refresh on the Chassis tab.
SNMP
Retry Count
Number of times Device Manager sends the same polling request if a response is not returned to Device Manager.
You may want to set this field to three or four.
Timeout
Length of each retry of each polling waiting period. When you access the device through a slow link, you may want to increase the timeout interval and then change the Retransmission Strategy to superlinear.
Trace
The trace field is used to enable and disable SNMP tracing. When Trace is selected, SNMP protocol data units (PDUs) are displayed in the Device > Log dialog box.
Register for Traps
When selected (enabled), automatically registers to received traps when Device Manager is launched against a device.
Max Traps in Log
The specified number of traps that may exist in the trap log. The default is 500.
Trap Port
Specifies the UDP port that Device Manager will listen on to receive SNMP traps.
