We know that a web-scale network is built with the help of smart people, processes and teams. That’s why Cumulus Networks Global Support Services (GSS) is available 24/7 to provide our customers with world-class support. Through GSS, our customers can leverage a full range of services including online support tools, access to the Cumulus Networks Global Support Center and coordination between hardware and software partners. We are here to make sure our customers and partners can easily manage Cumulus Networks solutions.

Support plans overview

Our support plans vary among Cumulus Networks products. When getting started with Cumulus Networks, be sure to look into the support policy that specifically applies to the products you’ve purchased. No matter which path you choose, Cumulus Networks GSS is here to help.

  • Cumulus Linux is licensed per switch. The license includes support and maintenance of the software. As long as you have an active license with Cumulus Networks, you'll have access to a range of support options.
  • Cumulus NetQ is licensed per Cumulus Linux switch. NetQ is a subscription-based license that includes support for 1, 3, and 5 years options. NetQ has one set of SKUs for 1G switches and one set of SKUs for switches that are 10G and greater. The NetQ agent can be installed free-of-charge on Ubuntu, Red Hat, and CentOS endpoint that is connected to a NetQ-licensed Cumulus Linux switch.
  • Cumulus Express comes preloaded and licensed with Cumulus Linux. The same exact software support applies to Cumulus Express customers, as well as a 3-year hardware warranty with the exception of RMP 1-year hardware warranty.

Support plans in detail

To give customers the flexibility to pick the right support options on their hardware and software, we defined our support packages as follows.

Software support

Support for Cumulus Linux comes bundled with the license to use the software. Terms of use can be on an annual, 3-year or 5-year basis.  Cumulus provides 24/7/365 support that includes:

  • Access to the Cumulus Networks online support tools
  • Access to support personnel
  • Access to downloads and software updates

Software Support for Cumulus products sold with Mellanox Hardware

Mellanox and Cumulus Networks have come together to provide a seamless support experience to our customers who have chosen to deploy Cumulus Networks software products with Mellanox Hardware. If you are a Mellanox + Cumulus customer, Mellanox will be your primary point of contact. The Cumulus GSS team works closely with Mellanox to resolve customer issues.

Mellanox support will contact Cumulus Networks GSS as required for resolution of a case, without requiring customers to open a separate case directly with Cumulus.

Hardware support for Cumulus Express

Our support policy covers hardware support for Cumulus Express. Cumulus Express comes in three different hardware types:

  • Fixed-configuration Cumulus Express switches (excluding RMP): the hardware warranty and return-to-factory for service or replacement period is three years. If you would like an extended warranty, you can purchase one or two years of additional hardware service at the time of purchase.
  • Modular or chassis-based Cumulus Express systems: the hardware warranty and return-to-factory for service or replacement period is three years. The period is the same for associated field-replaceable units (FRUs). If you would like an extended warranty, you can purchase one or two years of additional hardware service at the time of purchase.
  • Cumulus Express RMP (Rack management platform): the hardware warranty and return-to-factory for service or replacement period is one year. If you would like an extended warranty, you can purchase one, two, three or four years of additional hardware service at the time of purchase.  

Read the full Cumulus Express warranty policy here. For information on Cumulus Express pluggables, see “Transceiver and cable support,” below. 

Hardware support for devices not sold as Cumulus Express

If an issue is clearly due to faulty hardware, customers should contact the appropriate hardware partner directly for support and RMA requests.  If you are not sure that an issue is due to a hardware issue, Cumulus Networks can be included in the conversation with the hardware partner to provide root cause analysis details.

What about hardware spares?

Cumulus Linux licenses are transferable between hardware platforms. Therefore, customers running Cumulus Linux can enact a 'zero hour' sparing policy. If a hardware device fails, Cumulus Networks GSS can help you get a new device up and running.

Transceiver and cable support

The Cumulus Networks Hardware Compatibility List (HCL) provides a list of recommended transceivers and cables for each platform. That list identifies the first Cumulus Linux version that provided support for each module.

All Cumulus Express modules are supported by Cumulus Linux on all platforms that are capable of using them. These modules are qualified by Cumulus Engineering. For Cumulus Express pluggables, cables, DACs, AOCs and transceivers, the hardware warranty is one year.

In special circumstances, Cumulus Engineering may undertake qualification of a module on specific systems. That module would then be supported on future versions of Cumulus Linux.

For more about the policy, read this knowledge base article.

Premium support

Customers have an option to purchase expanded support services called Premium GSS. This premium support offering is designed for networks that have up to 1,000 switches that have Cumulus Linux installed as the network operating system. Customers receive all of the benefits of standard support services with a few added benefits including:

  • Increased service level agreements, for faster response times
  • A designated, named engineer who will respond to queries during business hours
  • Hardware partner liaison services which facilitate returns (RMAs) in the case of hardware defects or issues, eliminating the need to transact cases through multiple parties
  • Review and update sessions

    • Quarterly detailed network review
    • Semi-annual detailed support review
    • Yearly roadmap session with the Cumulus product team

Severity levels and Service Level Agreement (SLA)

If you do find yourself needing support from the GSS team, we know that time is almost always a concern. In order to provide our customers with world-class service, we provide transparent SLA scopes and times, so you’ll know exactly what to expect.

All cases are prioritized according to their impact on the customer and based on industry-standard definitions. Four normal support levels are offered — Severity 1 through Severity 4. Severity 5 is also available for issues that fall outside of normal support scope of coverage. During troubleshooting, priority can be either upgraded or downgraded at the customer’s request. The below SLA times indicate expected initial response time from a GSS engineer. Total resolution time will vary depending on complexity of the solution.

Severity Description SLA
Severity 1 (Urgent) A Severity 1 problem is a catastrophic problem that may severely impact the customer’s ability to conduct business. This may mean that the customer’s systems and/or products are down or not functioning and no procedural workaround exists. 30 minutes
Severity 2 (High) A Severity 2 problem is a high-impact problem in which the customer’s operation is disrupted but there is capacity to remain productive and maintain necessary business-level operations. 2 hours
Severity 3 (Normal) A Severity 3 problem is a medium-to-low impact problem that involves partial loss of non-critical functionality. The problem impairs some operations but allows the customer to continue to function. 8 business hours
Severity 4 (Low) This service level has minimal system impact, and usually amounts to feature requests and other non-critical questions. 12 business hours
Severity 5 (Other) This service level is for issues and requests that fall outside of normal scope of support coverage. As mutually agreed*

* Professional Services are available to provide additional support for non-standard support environments or requests.

Premium support:

Severity Standard support SLA Premium support SLA
Severity 1 (Urgent) 30 minutes 10 minutes
Severity 2 (High) 2 hours 30 minutes
Severity 3 (Normal) 8 business hours 4 business hours
Severity 4 (Low) 12 business hours 8 business hours

Escalation and change of severity

The best way to request a change in severity is to update the case and include details of why the severity change is required. Please describe the change in business impact as this will help GSS understand the best approach for this particular situation.

If you need urgent assistance at any time then open a new case (referencing the prior case number) or phone our support number and leave a message. The next available engineer will be alerted.
