Optimal Performance, Security, and Availability with Dedicated Device Management Channels

Out-of-Band Management (OOBM), also known as OOBM, is a crucial aspect of network management that involves using a dedicated management channel for device maintenance. In today's complex IT infrastructure, managing network devices efficiently ensures optimal performance, security, and availability. OOBM provides a solution to remotely monitor and manage these devices, offering system administrators greater control and flexibility.

Traditionally, managing network devices relied solely on in-band management, which requires the devices to be powered on and connected to the network. However, this approach poses limitations when the device encounters power failures, network disruptions, or operating system failures. Out-of-band management overcomes these limitations by establishing an alternate management channel that operates independently of the primary network connection.

What is Out Of Band Management (OOBM)

Out-of-band management (sometimes called OOBM) involves the use of a dedicated management channel for device maintenance (updates,fixes,firmware, etc). It allows a system administrator to monitor and manage network equipment by remoting into the device regardless of whether the machine is powered on, or if an operating system is installed or functional.

There are several reasons why routers may experience downtime, such as link failures, misconfigured access control lists, interface bouncing, accidental shutdown of the wrong interface, unresponsiveness after reboots, and DNS issues.

To address the challenges posed by an unreachable router, Cradlepoint's 4G LTE and 5G endpoints provide an effective OOBM solution that establishes a direct connection between the console port of the 4G LTE or 5G adapter and the router, enabling network administrators to connect to the router wirelessly. For situations where a connection to multiple routers is required, a USB-to-serial adapter hub can be used. This connection remains available even if IP and Ethernet functionalities are not working or accessible on the router.

By utilizing Cradlepoint's Remote Connect Out-of-Band Manager, administrators can diagnose and resolve issues without the need to physically visit the office, dispatch a truck, or rely on slow and costly POTS lines.

In-Band Management

With In-Band Management techniques offered by NetCloud, devices located behind a LAN router can be accessed from anywhere in the world. The NetCloud platform displays the IP addresses and host names of connected devices as they join the network. With the click of a button using Remote Connect, the IT team can enable cloud management for these devices.

Remote Connect LAN Manager enables administrators to establish connections and manage third-party devices on a Cradlepoint network using protocols such as HTTP, HTTPS, RDP, SSH, or VNC. Remote Connect LAN Manager also allows administrators to securely connect to and manage virtually any device on the LAN that has an IP address, eliminating the need for additional software or hardware to access previously inaccessible devices.

Remote Connect to Cradlepoint device UI provides comprehensive router-level data, including the status of Remote Connect interfaces, VPN tunnel status, router tables, system logs, connected client lists, firewall tracking, hit counters, and more. It also functions as a remote access point to the UI of each router, allowing users to access it ssecurely and remotely, on demand. Organizations can leverage this service for real-time troubleshooting and gain vluable insights into routing tables, connected clients, and data usage.

With Remote Connect Console Access, IT departments gain more in-depth access to data previously available only through CLI access, including real-time analytics and routing tables. This information can be used to identify issues like slow service or misdirected traffic so that the IT team can take immediate corrective actions.

Benefits of OOBM for Your Business

Implementing out-of-band management offers several significant benefits for businesses, enhancing operational efficiency, reducing costs, and improving overall network resiliency.

Uninterrupted Service Availability

OOBM ensures that critical network devices can be accessed and managed even when the primary network connection is disrupted. System administrators can remotely troubleshoot and resolve issues by establishing a dedicated management channel, minimizing downtime and maintaining service availability.

Enhanced Security

Security is a top priority for any business, and OOBM helps bolster network security measures. Organizations can implement stringent access controls, encryption, and authentication mechanisms for out-of-band connections by having a separate management channel. This ensures that only authorized personnel can access and manage network devices, reducing the risk of unauthorized access or tampering.

Rapid Troubleshooting and Issue Resolution

When an IT asset loses its network connection, traditional systems management applications can only provide limited information about the problem. OOBM enables system administrators to remotely access the device, regardless of its power status or operating system functionality. This allows for swift troubleshooting, diagnosis, and resolution of issues without needing physical intervention.

Cost and Time Savings

The traditional approach to restoring network connectivity requires on-site technicians to physically interact with the affected devices. This process involves travel time, equipment setup, and manual intervention, leading to increased costs and downtime. With OOBM, the need for local management and site visits is significantly reduced. System administrators can remotely restore devices to the network infrastructure, saving time and operational expenses associated with on-site visits.

Scalability and Centralized Management

As businesses grow and expand their network infrastructure, managing an increasing number of devices becomes a challenge. OOBM offers a scalable solution, allowing administrators to efficiently manage and monitor multiple devices from a central location. This centralized management approach improves productivity, reduces complexity, and ensures consistent configurations across the network.

Compliance and Auditing

Certain industries have strict compliance requirements that necessitate thorough monitoring and auditing of network devices. OOBM provides comprehensive logging and monitoring capabilities, enabling organizations to meet compliance standards by tracking device activities, changes, and access. This facilitates regulatory audits and helps maintain a secure and compliant IT environment.
