Norstar Version - IP Office Info

5.1.5.3 Discovery
This tab is accessed through File | Preferences and then selecting the Discovery sub-tab.
These settings affect the Select IP Office menu used by Manager to discovery IP Office systems. By default IP Office 3.2
systems respond to both UDP and TCP discovery. Pre-3.2 IP Office systems only support UDP discovery.
· TCP Discovery: Default = On
This setting controls whether Manager uses TCP to discover IP Office systems. Only IP Office 3.2 and higher
systems can respond to TCP discovery. The addresses used for TCP discovery are set through the IP Search
Criteria field below.
· NIC IP/NIC Subnet
This area is for information only. It shows the IP address settings of the LAN network interface cards (NIC) in
the PC running Manager. Double-click on a particular NIC to add the address range it is part of to the IP Search
Criteria. Note that if the address of any of the Manager PCs NIC cards is changed, the Manager application
should be closed and restarted.
· IP Search Criteria
This tab is used to enter TCP addresses to be used for the discovery process. Individual addresses can be entered
separated by semi-colons, for example 135.164.180.170; 135.164.180.175. Address ranges can be specified using
dashes, for example 135.64.180.170 - 135.64.180.175.
· UDP Discovery: Default = On
This settings controls whether Manager uses UDP to discover IP Office systems. Pre-3.2 IP Office systems only
respond to UDP discovery. By default IP Office 3.2 and higher systems also respond to UDP discovery but that can
be disabled through the IP Office system's security settings.
· Enter Broadcast IP Address: Default = 255.255.255.255
The broadcast IP address range that Manager should used during UDP discovery. Since UDP broadcast is not
routable, it will not locate IP Office systems that are on different subnets from the Manager PC unless a specific
address is entered.
· Use DNS: Software level = IP Office Manager 6.2+.
Selecting this option allows IP Office Manager to use DNS name (or IP address) lookup to locate an IP Office
system. Note that this overrides the use of the TCP Discovery and UDP Discovery options above. This option
requires the IP Office IP address to be assigned as a name on the users DNS server. When selected, the Unit/
Discovery Address field on the Select IP Office menu is replaced by a Enter Unit DNS Name or IP Address
field.
· SCN Discovery
If enabled, when discovering IP Office systems, the list of discovered systems will group IP Offices in the same
Small Community Network and allow them to be loaded as a single configuration. IP Office Essential Edition -
Norstar Version systems are not supported in a Small Community Network.
