Zones
As NetXMS server keeps track of IP topology, it is important that IP addresses do not overlap and that two IP addresses from same subnet are really within one subnet. Sometimes, however, it is needed to monitor multiple sites with overlapping IP address ranges. To correctly handle such situation, zoning must be used. Zone in NetXMS is a group of IP subnets which form non-overlapping IP address space. There are always zone 0 which contains subnets directly reachable by management server. For all other zones server assumes that subnets within that zones are not reachable directly, and proxy should be used.
Enable Zoning
Zoning support is off by default. To turn it on you must set server's configuration variable EnableZoning to 1 and restart server. After restart, server will create default zone with ID 0 and put all existing subnets into that zone. Subnet tree will looks like this:
Setting communication options for zones
Server have to know proxy nodes to be able to communicate with nodes in remote zones. Default proxy settings for all nodes in the zone can be set on Communications page in zone object properties:
On this page you can set default proxy node for NetXMS agents, SNMP, and ICMP. Note that proxy node must be in default zone and must have primary IP reachable by NetXMS server.
Moving nodes between zones
To move existing node to another zone, select Change zone... from nodes context menu, then select target zone in zone selection dialog that will appear. After move to another zone, server will immediately do configuration poll on the node.
