Out-of-band management & network labs
Out-of-band (OOB) management is a second, independent path to your network equipment. When a configuration mistake or an outage takes the production network down, a console server with a serial connection and a cellular uplink still lets an engineer reach the device. We deploy console servers from vendors such as Opengear and Lantronix, with LTE failover and central management.
What we do
- Console-server design with serial, LTE and break-glass access
- Out-of-band network isolated from production routing
- Zero-touch provisioning for new branch and remote sites
- Secure ZTP planning against RFC 8572 where devices support it
- Containerlab and EVE-NG labs that mirror the production topology
- Batfish validation of planned changes before the window
- Lab-tested change plans with rollback steps
- Central management and audit of console sessions
New sites should not need an engineer on the floor. Zero-touch provisioning (ZTP) lets a device in its factory state fetch its boot image and initial configuration automatically; RFC 8572 defines the secure standard version for NETCONF-managed devices. We pair it with the automation and source-of-truth tooling described in our network automation group.
Changes are rehearsed before they touch production. Containerlab, EVE-NG and GNS3 build virtual copies of a topology from real or virtual router images, and Batfish checks the planned configurations for routing and reachability errors. This is part of our Managed IT service and the reason our network changes come with a tested rollback.

Send us a messageWhy not just manage devices over our VPN?
A VPN rides the production network, so a configuration mistake or an outage that takes the network down can take your access with it. Out-of-band management is a second, independent path: a console server with a serial connection and a cellular uplink that still reaches the device when production is down.
What is zero-touch provisioning?
Zero-touch provisioning (ZTP) lets a device in its factory state fetch its boot image and initial configuration automatically, so a new site does not need an engineer on the floor. Secure ZTP (RFC 8572) is the standard version for NETCONF-managed devices. We pair it with our automation and source-of-truth tooling.
Does every device support secure ZTP?
No. We plan against RFC 8572 where devices support it. Support differs by model and software version, so we confirm it per device before a rollout and describe the alternative when a model falls short.
What is a network lab used for?
Containerlab, EVE-NG and GNS3 build virtual copies of a topology from real or virtual router images. We rehearse changes there and use Batfish to check the planned configurations for routing and reachability errors. The change reaches production with a tested rollback plan.
How do you keep the out-of-band network from becoming a back door?
We isolate it from production routing, restrict who can reach the console servers, and use central management and audit of console sessions. Serial console and break-glass access are designed as controlled exceptions with logs, not as a shortcut around normal access.
Does a successful lab test guarantee the change is safe?
No. A lab shows that the design and the configuration work as intended, and it catches many mistakes early. Virtual images can behave differently from the real hardware, so the plan still has a change window, validation steps and a written rollback.
