LAN (Subnets)

When your network devices are loaded into IT Glue, you'll notice that you have a way to easily see all your network devices using the Configurations list view. If you have a lot of devices, this list can be filtered and ordered. For example, if you needed to see just the Managed Servers, you could filter by Managed Server:

To document the subnets, use the LAN flexible asset. With this flexible asset, you're primarily adding links to key devices, so that you can later fetch one from the other and vice-versa. It was designed simply and is a great example of an asset that can be expanded over time.

Note that if traffic on the network is separated using VLANs, the LAN flexible asset is where you should document the VLAN configurations, adding links to the relevant switches. Alternatively, if the VLAN is completely separate despite being connected to the same router (e.g. a guest wireless network), you could consider creating the VLAN as a sub-organization instead. This lets you make sure the VLAN configuration has more visibility whenever there is an issue to troubleshoot. For more information on using sub-organizations, see Working with sub-organizations.

Prerequisites

  • Load all the network attached devices in the client environment as configuration items.
Visit Account > Flexible Asset Types > LAN to ensure the available fields and drop-down options are in line with the information you wish to capture. Suggested additions: key internal DNS entries, switch routing, DHCP options, and managed UPS systems.

Instructions
