DESCRIPTION
Set the number of seconds (1~5) the ENC has to wait for a device's response, before the
ENC polls the device again. If the device does not respond after the number of retries
you set, then it is deemed to be down.
Set the number of times (0~3) the ENC resends a poll message to a device if the device
does not respond. 0 means the ENC will not poll the device again if a response is not
received the first time.
Select whether the ENC performs a scan afresh (Root subnet / Complete) or a scan
for devices that have not been added to the OTV panel yet (Root subnet /
Incremental).
Select whether to scan devices on a basis of networks or IP addresses.
Entire Network - Select this to scan devices in the ENC's network or a designated
network(s) depending on the seed settings you will configure later.
IP Range - Select this to scan devices in an IP address range.
This field is available if you selected Entire Network in the Discover Type field. Enter
the number of gateways to across from the specified seed(s). 0 means to scan the
network where the specified seed host is located.
Click this to add a seed for auto-discovery.

172.17.2.254 with a subnet mask of 255.255.0.0. Click Ok to save the changes and
close this screen or Cancel to exit this screen.
