Polling Interval
AT-View Plus 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 AT-View Plus Device Manager waits before it determines that the
device is not responding. The default is 5 seconds.
Retry times
The number of times AT-View Plus Device Manager sends SNMP messages to the agent
before giving up. The default is 2 retries.
Enable 'Trap' operation
To receive traps from a target host's SNMP agent, check this box.
Note - If SNMPc, HP OpenView or Tivoli NetView is running, AT-View Plus Device
Manager will not receive any traps. This is because the traps are being intercepted by the
network management application and will never reach AT-View Plus Device Manager.
Enable periodic device polling
To regularly check the hardware configuration of hot-swappable devices, check this box.
When this is checked, AT-View Plus 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 - AT-View Plus 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 AT-View Plus 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.
