Polling Interval
Device Manager sends a GetRequest to the SNMP agent at predefined
polling intervals to ensure that it is still connected to the device. If a
shorter or longer interval is required adjust the value in the Polling
Interval field accordingly.
The minimum interval is 5 seconds and the maximum is 3600 seconds (1
hour). The default is 30 seconds.
Retry
Configures the SNMP timeout and the number of retries.
Timeout
The number of seconds Device Manager waits before it determines
that the device is not responding. The default is 5 seconds.
Retry times
The number of times Device Manager sends SNMP messages to the
agent before giving up. The default is 2 retries.
Enable periodic device polling
To regularly check the hardware configuration of hot-swappable devices,
check this box. When this is checked, Device Manager checks the
hardware configuration at every polling interval. The Panel window shows
any hardware configuration changes it finds.
If the target device is not hot-swappable, or if you do not expect any
hardware configuration changes, do not check this box. Polling the
hardware configuration may reduce performance.
Note - Device Manager always checks the latest hardware configuration of
the target device when initiating connection. To check the configuration
on demand after the session is established, select View > Refresh.
Current status
Indicates whether or not Device Manager is currently connected to a
target device and whether or not Trap operations are currently enabled.
5.1.2 Reopen
This command can be used to reconnect to a recently accessed device.
