Device Manager communicates with the Accelar Management Software using Simple Network Management Protocol (SNMP). The Device Manager Properties window allows you to configure important communication parameters such as the polling interval, timeout, and retry count. You can set these parameters before you open a device to manage. You can also access the Properties window at any other time while Device Manager is running.
To access the Properties dialog box:
| The Device Manager Properties dialog box opens. |
The table below describes the Properties parameter fields.
Field
Description
Status Poll 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 in the chassis window.
Status Poll Interval
Interval at which statistics and status information are gathered (default is 300 seconds).
Retry Count
Number of times Device Manager retransmits polling information.
Timeout
Length of each retry of each polling waiting period. When accessing the device through a slow link, you may want to increase the timeout interval and then change the Retransmission Strategy to superlinear.
Retransmission Strategy
Can be one of the following:
Linear--sends a request based on retry count x timeout. For example, a retry count value of 3 and a timeout value of 3 means that information is requested three times at 3-second intervals.
Superlinear--sends a request based on retry count x timeout (doubled). For example, a retry count value of 3 and a timeout value of 3 means that information is requested three times:
Hotswap Poll Interval
The interval at which Device Manager polls for module information. The default is 600 seconds.
Max Traps in Log
The specified number of traps that may exist in the trap log. The default is 500.
Display Hostnames As
Select to display names either in Domain Name System (DNS) format or IP address format.
Display SNMP Errors In
Display SNMP errors from the status bar or from a separate error window.

Note:
By default, Device Manager attempts to resolve DNS names to IP addresses. If no DNS server is available, the DNS resolution attempts may result in long delays and sluggish Device Manager response. To avoid this situation, set the Display Hostnames As field to IP addresses.
