Bridges represent a connection from the EZ UDM Pro server, cloud-based or on your own network, to the devices that you manage. Additionally, they provide a local repository for the data and software that your devices use. Instead of retrieving data from a cloud-based repository, local data storage allows network speed access for the devices that you manage instead of the possible inconsistencies in latency and speed that the Internet can introduce.
Unlike other components in EZ UDM Pro, Bridges are not added by using the user interface. Bridges are added by installing the EZ UDM Pro Bridge software on a server on your local network. When installed, the bridge software registers with the target EZ UDM Pro server.
The bridge, once registered with the EZ UDM Pro server, cannot have a dialog with the command and control portion of EZ UDM Pro until the EZ UDM Pro administrator approves the bridge. This is a security measure, preventing rogue bridges (or computers that look like bridges) from accessing your system. Once approved, devices that connect to the bridge are can receive data and report back information to EZ UDM Pro.
To add a bridge, do the following. (Complete details are presented in the accompanying Installation Guide.)
- On the server that will serve as a provisioning bridge, launch the EZ UDM Pro Bridge installer as an administrator. On the Welcome dialog, click Next.
- In the dialog "Select Installation folder", accept the default location (C:\Program Files\Event Zero\EZ UDM Pro Bridge) for the bridge files. Alternatively, Browse and select or type a location that you want to install the files to. Click Next.
- In the dialog Settings, enter the https uniform resource locator (URL) for your EZ UDM Pro tenant (cloud-based) or server (on-premises).
- Click Install to begin the installation of the bridge.
- When finished, click Finish on the Completed screen.
Installing the EZ UDM Pro Bridge software on your local server registers the bridge with EZ UDM Pro. You, as an Administrator on EZ UDM Pro, must approve the bridge to allow it to communicate and establish a full dialog with the application. To approve a bridge, do the following.
- In EZ UDM Pro, select Bridges from the sidebar.
- On the Bridges dialog page, scroll through the list or filter the list of registered bridges. Look for the name of the newly registered bridge or look for bridges that have a status of "Bridge awaiting approval", indicated by a yellow triangle.
- Under Actions, click the Approve bridge for provisioning icon on the right.
- On the Confirmation dialog, click Approve or click Cancel to discard your changes.
- Successful approval of the bridge will result in the yellow triangle changing to a green check mark.
- Bridge Name – A read-only field indicating the name that the bridge registered as. This is the hostname of the server as it is registered
- Note – A text field allowing the EZ UDM Pro administrator to add notes to the bridge entry
- Devices Connected – The number of devices that have registered with this bridge
- First Seen – The amount of time that has passed since this bridge was first seen, typically when the bridge registered with EZ UDM Pro
- Last Seen – The amount of time since the bridge last communicated with EZ UDM Pro. Bridges communicate and query with EZ UDM Pro occasionally to receive updates and new software or configurations assigned to it. An extended period since 'Last Seen' suggests that there is a possible problem with the bridge or the network that the bridge is on.
- Alert time for a device not being seen - Toggle to enable the Time Threshold Option
- Time threshold - This option appears when the Alert time is turned on.
- Set the days and hours to be exceeded before a device attached to the bridge is highlighted in the last seen column. For example
- Tag Enabled - If the tag is enabled the tag priority order option is enabled. When the tag is enabled it is positioned in the last priority number position.
- Tag priority order - The position number of the Tag. Clicking on the Tag order pops up a menu showing all the tags and you can drag and drop to change the priority order.
- Bridge Log Level - this is used for diagnostic by Enoten personnel
- Click the Prevent bridge from provisioning icon associated with the bridge you intend to delete. This action stops the bridge from responding to all devices associated with this bridge.
Note! If you need to remove the server from service temporarily and intend to return it to service but are not changing servers, you would use Prevent bridge from provisioning to prevent it from responding to devices. You then can maintain the server and later click Approve bridge for provisioning to return it to service and managing devices.
- Give the bridge five minutes to quiesce and finish any outstanding operations that might be in queue.
- Click Delete (trash can icon) to remove the bridge from the Bridges listing.
- The server where the EZ UDM Provisioning Bridge software is installed is now available to have the bridge software removed and the server repurposed or retired.
