In-Band Management vs. Out-of-Band Management
There are plenty of remote monitoring and management (RMM) solutions available in the market. Many are software based, allowing IT administrators to manage devices from a single interface. However, these software-only solutions are limited, since they depend on in-band management.
Benefits of Out-of-Band Management
With out-of-band management, any device that has access to a network connection and a power source can be managed. IT teams can reach devices whether they are powered on or off, located on- or off-site, or are inside or outside the corporate firewall. This translates into several business benefits.
What is in band?
In-band refers to managing through the network itself, using a Telnet/SSH connection to a router or by using SNMP-based tools. In-band is the common way to manage the network, where actual data/ production and management traffic may use the same path for communicating with various elements.
What is in band management?
It is a common way that provides identity based access control for better security. It is good practice to segregate your management traffic from your production customer traffic. Create a management VLAN or loopback interface for other management activities such as device monitoring, system logging and SNMP.
When is an alternate path required to reach the network nodes?
When network is down and traffic is not flowing, in such a scenario, an alternate path is required to reach the network nodes. Here we need a secure remote emergency network access path to manage and troubleshoot the device when network traffic is down. For critical networks, in-band management tools are not enough. Management using independent dedicated channels is called OOB. OOB provides accessibility when an alternate path is needed to access the network nodes.
How does OOB work?
In-band works when network link is up and OOB is alternate path when network goes down. In-band is Synchronous and OOB is Asynchronous. In-band requires no physical access and OOB also does not require physical access because dial line is available. In-band connection speed is high and OOB connection speed is slow.
What is an out of band management card?
Both in-band and out-of-band (OOB) management are usually done through a network connection, but an out-of-band management card can use a physically separated network connector if preferred. A remote management card usually has at least a partially independent power supply and can switch the main machine on and off through the network.
What is remote management?
Remote management can be used to adjust BIOS settings that may not be accessible after the operating system has already booted. Settings for hardware RAID or RAM timings can also be adjusted as the management card needs no hard drives or main memory to operate.
How Does Out-of-Band Management Work?
Out-of-band management is typically enabled through a serial console port, such as RS-232, which provides a command line interface for troubleshooting routers, servers, switches, power controllers, storage devices and other equipment. This enables administrators to configure, reboot, and reset devices if the primary network becomes unavailable.
What is the most effective approach to out of band management?
Several factors distinguish the most effective approach to out-of-band management. One of these is wireless connectivity. Many organizations provide back-up for primary copper or fiber connections with a secondary wired line to regional distribution centers and branch locations. However, back-up lines can be vulnerable to the same hazards that can affect a primary wired line.
What is OOB in IT?
Out-of-band (OOB) management is a method of remotely controlling and managing critical IT assets and network equipment using a secure connection through a secondary interface that is physically separate from the primary network connection. This enables administrators to gain control even during infrastructure faults.
What to do when a network goes down?
When a network goes down, or a remote device goes offline, IT administrators need a way to connect to field hardware and restore normal operation. The best way to do that is with secure out-of-band management.
Is 24/7 connectivity a requirement?
For administrators managing critical IT infrastructure in remote locations, 24/7 connectivity is a business necessity. But connectivity can be impacted by many things, from weather events, to configuration failures, to human error, or even distributed denial-of-service (DDoS) attacks. Whatever the cause, an unplanned outage that disrupts the ability to manage and run a business is costly. Out-of-band management is a requirement for every network manager’s toolkit.
How to implement out of band network management?
You implement out-of-band network management by deploying these serial console servers at every office, remote branch, data center, and other physical sites. By physically connecting your OOB serial consoles to critical network devices like routers, switches, and servers, you ensure engineers and administrators can always reach those devices without an IP address. That means your management plane is always available, even if your ISP connection goes down.
Why is out of band network management important?
If your enterprise has many remote sites spread out over a wide geographical area, out-of-band network management can simplify remote infrastructure troubleshooting and support. Rather than hiring a technician for each region or paying to fly out your engineers every time there’s an issue, your team can fully support all your remote sites from a centralized location.
What is OOB network management?
OOB network management provides higher-level remote access and control capabilities for multiple devices from one pane of glass. If your primary network experiences an outage, you can use OOB to reboot routers, troubleshoot connection problems, or perform device health checks.
What is OOB network?
Out-of-band (OOB) network management provides a secure, remote connection to your network that’s available during outages, breaches, and other service disruptions. It does this using a network that’s specifically dedicated to infrastructure management and is completely independent of your primary network. OOB uses serial console servers to create an alternate path to critical network devices with a separate management plane, typically using a 4G LTE cellular connection to provide you with uninterrupted access to your network.
Why use OOB in data center?
Using OOB to monitor and manage servers and appliances remotely, engineers can control multiple facilities from one central console, saving time and reducing the number of staff required at each location.

The best part is that you can access your out-of-band serial console servers from anywhere in the world – so your team can respond to issues at remote sites just as quickly as at your main office.
What is out-of-band access?
Out-of-band refers to the way you can access your device “outside” of its typical (in-band) channels. Servers, routers, switches, miners, desktop PCs, etc. are typically connected to the local network and the internet via an Ethernet port. HTTP requests and other types protocols must physically go through this channel. In most cases, an Ethernet port or WIFI card is referred to as the in-band access, because it is the primary channel of communication to the device. Out-of-band access is any method of communication that does not rely and is independent of primary channel of communication.
What is a console server and why is it an out-of-band solution?
A console server is simply a device that gives you remote, out-of-band access to your host’s command line (also referred to as shell/console/terminal). A console server accomplishes this by tapping into your host’s other method of communication: Serial Port.
Resilience for Your Network
Out-of-Band management’s primary application is to provide secure, remote access to your critical devices even when the primary network is down. It offers presence and proximity to your distributed network, with a console server at every location, physically connected to routers, switches and key hardware.
For Day One, Every Day, and When the Network Goes Down
