This article shows you how to match unmatched network devices discovered by the Network Glue Collector and create new IT Glue configurations if required.
Scheduled device matching
IT Glue will attempt to match incoming Network Glue data to existing IT Glue configurations following each network scan. This is done by automatically matching the MAC address discovered by the Network Glue Collector to existing IT Glue configuration's primary or non-primary MAC addresses.
If a network device has more than one MAC address (e.g. due to several Network interface cards), IT Glue will always attempt to match MAC addresses collected by the Network Glue data to a single IT Glue configuration if multiple MAC addresses were logged.
RMM MAC address automatching
To ensure a higher matching ratio, network devices are matched to your RMM devices based on the RMM MAC address. If a network device has a MAC address identical to the MAC address of an IT Glue configuration with information overlaid from your RMM, an automatch is created during the scheduled matching.
Manual device matching
The device matching page gives an overview about discovered network devices and their matching status. From here you can quickly evaluate which devices have been matched, adjust or create matches, create new IT Glue configurations based on network data or choose to ignore particular devices.
Why are my network devices not matched through the scheduled device matching?
In some scenarios, Network Glue data may not be automatically matched to existing IT Glue configurations. Refer to the table below for these scenarios and steps you can take to match your devices.
|Possible Scenarios||Next Step|
|A MAC address collected by Network Glue matches more than one IT Glue Configuration.||Perform a manual match via search.|
|Multiple MAC addresses detected by Network Glue match a MAC address of more than one IT Glue Configuration.||Perform a manual match via search.|
|A MAC address collected by Network Glue does not match the MAC address of an existing IT Glue configuration synced with an RMM.||Network Glue performs the automatch algorithm based on MAC addresses that are part of an IT Glue configuration.|
|MAC address for a network device is not detected by Network Glue**||Check if there is a firewall or other security settings that are blocking access to the devices. You can do so by checking if the devices and the Network Glue Collector host machine are pingable in both directions.|
**Why isn't matching or creation or a device without a MAC address allowed?
Each time a network data set is collected, matching is performed based on the MAC addresses. If you have manually matched or created a configuration with no MAC address before the most recent sync, the system has no way of identifying this device during the next sync. Even if a configuration without a MAC address is created and added manually, you will end up with a MAC address configuration but a network device without a MAC address. Under these circumstances, no match can be created.
- You will need Administrator or Manager level access to utilize the device matching page.
- To navigate to the device matching page, click the Device Matching button in a network diagram.
- On this page, you can view, filter, and search a list of Unmatched, Matched, and Ignored devices by clicking each of the three categories. In the table, you can filter and sort by Device Type, Network Device, and whether SNMP is enabled or disabled.
The tables below show content that can be found in each category and the actions available per category.
|Unmatched||Devices that could not be matched automatically during the scheduled device matching.||
Devices that were matched either automatically or manually.
Note: You can distinguish between devices that were either automatically or manually matched during the scheduled device matching.
|Ignored||Devices that have been manually ignored by an Administrator or Manager.||
|Manual Match via search||
Search for an IT Glue configuration and match it to a network device manually.
Configurations that match your search criteria will appear as you type. Clicking on an IT Glue configuration in the search results will match this configuration instantly.
Automatch as needed based on MAC addresses. IT Glue attempts to find the most current and accurate match automatically.
Example: Click on Automatch if configuration data has been created or updated since the most recent Network Glue data sync.
|Create||Create a new IT Glue configuration based on the given Network Glue data.|
|Ignore||Ignore a discovered network device. Ignored devices will no longer appear in the Unmatched or Matched categories in all subsequent network discoveries.|
Matching Hyper-V hosts, VMware hosts, and VM data
If you added VMware host data during the Collector setup, Network Glue will discover your VMware guests like all other devices. To have Hyper-V hosts and guests be discovered automatically as well, you will need to toggle on the “Scan Active Directory” switch during the Collector setup and add your AD credentials. All of these can be actioned by following our Setting up Network Glue for an IT Glue organization KB article.
|Device||Network Glue Device||IT Glue Device|
|Virtual switch||Virtual switch||Virtual switches do not have MAC or IP addresses. So, they cannot be created as IT Glue configurations.|
|Hyper-V guest, or VMware guest||Virtual machine||
When creating a new configuration from the Network Glue device, a “VM” device type is applied.
When matching to an existing IT Glue configuration and an IT Glue device is missing, a “VM” device type is applied.
When matching to an existing IT Glue configuration that has a device type, the existing device type in IT Glue is applied.
|Hyper-V host, or VMware host||VMware and Hyper-V hosts are devices (e.g. server) already discovered by Network Glue.|
Creating a new configuration
If a device is not automatically or manually matched to an IT Glue configuration, you have the option of creating a new IT Glue configuration based on the information gathered by the Network Glue Collector. The below table describes how Network Glue data is mapped to IT Glue configuration fields.
|Network Glue device>||IT Glue configuration|
|Device type (router, switch, server, computer, printer, network device)||Type|
|IP address||Interfaces - IP address|
|MAC address||Interfaces - MAC address|
|Physical location||Physical position|
