Specify search, response, and keepalive intervals for a Hub
You can specify the search and response time for Hubs on the network, and the keepalive intervals for the connection between the Hub and the AnywhereUSB Manager.
- Open AnywhereUSB Manager.
- Choose File > Preferences. The Preferences dialog appears.
- Click the Advanced tab.
- Enter the following:
- Search for Hubs every .... sec: Specifies how often the AnywhereUSB Manager searches the local network to discover Hubs and refresh the AnywhereUSB Manager display. Default and minimum values are both 30 seconds.
Note You cannot manually perform a refresh of the Hubs displayed in the AnywhereUSB Manager.
- Wait for Hub response for .... sec: Specifies the time interval from the last discovery refresh that the AnywhereUSB Manager will stop looking for more Hubs. Default and minimum values are both 4 seconds.
- Send Keep-Alive every ... sec: Specifies how often the AnywhereUSB Manager sends a keepalive request to the Hubs connected to the network. This impacts network utilization because each AnywhereUSB Manager will send one packet at this interval to each Hub to which it is connected. Default is 3 seconds. The minimum value is 1 second.
- Keep-Alive Timeout ... sec: Specifies how long the AnywhereUSB Manager should wait for a keepalive response. When the value of the response time is reached, the Manager decides that a Hub is no longer available, and the computer is disconnected from all groups and devices on that Hub. The default value is 20 seconds. The minimum value is 15 seconds.
- The keepalive timeout value would need to be longer if the network has more latency (such as a cellular or satellite link), or an internet link with unreliable packet delivery.
- If the value is too short, devices will be disconnected, which may have an adverse affect on some devices, such as USB memory.
- If the value is too long, Hubs that are removed from the network will not be noticed as gone for a long time, and devices that are no longer connected will be unresponsive for a long time.
- Power cycle off time: This option is not used, and any value in the field is ignored. The power cycle off time configured for the Hub is 1 second.
- Search for Hubs every .... sec: Specifies how often the AnywhereUSB Manager searches the local network to discover Hubs and refresh the AnywhereUSB Manager display. Default and minimum values are both 30 seconds.
- Click Save.
