2.18.9 Managing network connections in a multi-server configuration
In a multi-server configuration, the network connections of the devices can be controlled by the primary management server or management relay servers.
There are two ways you can manage network connections:
-
Managing network connections linking with JP1/NETM/NM - Manager
-
Managing network connections using the network monitoring function
Managing network connections linking with JP1/NETM/NM - Manager
If you want to manage the entire network connections by the primary management server, install JP1/NETM/NM - Manager only on the primary management server. If you want to manage network connections by each management server, install JP1/NETM/NM - Manager on each management server.
If you want to manage the entire network connections by the primary management server, configure the automatic update target of the network control list to include the management relay servers under the primary management server. By doing so, connection information of the corresponding managed device (MAC address and IP address) is automatically added to, changed in, or deleted from the network control list based on the device information reported by the management relay server. By default, the automatic update target does not include the management relay server under the local server.
Even when you configure the automatic update target of the network control list to include the management relay servers under the primary management server, the network connection settings for the devices managed in the management relay servers under the local server must be performed on the management relay servers that manage those devices. The note is shown below:
-
On the setting dialog of the network control list of the primary management server, you can change the connection settings of the devices managed in the management relay servers under the local server but they are overwritten by notification from the management relay servers under the local server.
In addition, if multiple NICs are installed on a device, when you configure one NIC to allow access on the management relay server, all the NICs are allowed to access on the primary management server.
- Important
-
If you configure the automatic update target of the network control list to include the devices managed by the management relay servers under the local server in a NAT environment, multiple devices with the same IP address might be added to the network control list. Therefore, if the judgement method for network connection is set to IP address, problems might occur, such as unintentional disconnection of a business-purpose device. We recommend that you choose MAC address or MAC address + IP address if you want to include the devices managed by the management relay servers under the local server in the automatic update target in a NAT environment.
Managing network connections using the network monitoring function
You can manage network connections on each management server using the network monitoring function of JP1/IT Desktop Management 2.
If you use the network monitoring function to manage network connections, there is no functional difference with managing network connections in a single-server configuration.
