How to Sell Used Network Equipment: Licensing, Wiping and Resale Steps

Switches, routers, firewalls and wireless access points are often retired long before they stop working. A refresh cycle ends, a vendor announces that a product line is being phased out, or an office closes. Selling the hardware can recover part of its cost and keep working equipment in use. But network gear is not like a laptop. It runs vendor software with licensing rules, it stores configuration data that can reveal how your network is built, and buyers care about its support status.

This guide walks through the steps in a sensible order. It uses Cisco's published policies as the worked example because they are public and specific. Other vendors have their own rules, so always read the terms for the brands you own. This is general information, not legal advice.

Step 1: Take an inventory and check each device's lifecycle status

Start with a list: make, model, serial number, software version, location and who last used it. You will need this for the buyer, for your records and for removing the devices from your own systems later.

Then look up the lifecycle status of each model. Vendors publish end-of-life notices, and buyers will check them. Cisco's end-of-life policy defines the milestones this way:

  • End of Sale: the product is no longer offered for sale after this date.
  • Last Date of Support: the last date to receive support as entitled by active service contracts for covered hardware and software.
  • End-of-Life: a process that guides the final business operations of a product's life cycle; once its technical and business milestones are complete, the product is obsolete and is no longer sold, improved, maintained or supported.

Cisco also states that external notification of end of sale is typically six months before the end-of-sale date, and that the last customer ship date for hardware is three months after the hardware end-of-sale date.

Why does this matter when selling? A model that is still sold and supported is a different proposition from one that passed its last date of support. Buyers may want the milestone dates, and you will want to describe the equipment accurately rather than imply support that no longer exists.

Step 2: Understand the software licensing before you list anything

This is the step sellers most often skip, and it is where network gear differs most from other IT equipment.

Cisco's relicensing page states that Cisco hardware may be freely resold or leased. It also states that the software embedded in the hardware, and Cisco standalone software, is not transferable unless specifically allowed under the Cisco Software License Transfer and Re-Use Policy. Where a transfer is permitted, the page says it requires Cisco's written consent and payment of a license fee. For buyers of used or secondary-market equipment, Cisco states that they must acquire a new license from Cisco before the software can be used.

Two further points from Cisco's page are worth passing on to any buyer:

  • Used and secondary-market equipment is not covered under the Cisco standard warranty.
  • To obtain a support contract on such equipment, the buyer must show proof of a valid license and have the equipment inspected, through Cisco's hardware inspection and software relicensing program.

For the seller, this means three things. First, be accurate: you can sell the hardware, but do not tell a buyer that the operating system license comes with it unless you have confirmed the vendor allows that. Second, put the licensing position in writing in the sale terms, so the buyer knows they are responsible for their own software rights. Third, if your devices carry licensed features or subscriptions, check the vendor's account tools for what can be moved or ended before you hand the devices over.

If you own another brand, search for its "software license transfer" or "secondary market" policy before listing. Rules vary by vendor.

Step 3: Remove your data and your credentials

A switch or firewall does not hold files like a laptop does, but its configuration can include things you would not want an outsider to have: IP addressing plans, VLAN layouts, user accounts, shared secrets and certificates. Treat the device as a storage item that needs sanitizing.

NIST's media sanitization guidance (Revision 2, September 2025) gives a useful principle for this kind of equipment. It notes that for devices such as a basic cell phone or a piece of office equipment that only provide the ability to return to a factory state and do not support rewriting, manufacturer resets and procedures that do not include rewriting may be the only clear sanitization option, and these still meet the definition of the clear method as long as the device's interface does not allow retrieval of the original data.

In practice that means:

  1. Follow the manufacturer's documented reset and erase procedure for the specific model, and not a procedure you remember from an older model.
  2. Remove or revoke credentials elsewhere. Take the device out of monitoring tools, remove its entries from authentication servers and rotate any shared secrets or keys that were stored on it.
  3. Check for removable storage. Some devices accept flash cards or contain internal drives that may need separate sanitization. If a device has a storage module you cannot reset to your satisfaction, physical destruction of that module may be the safer choice. Our guide to hard drive shredding vs degaussing explains the options.
  4. Record what you did. NIST recommends a certificate of sanitization for each piece of media, recording details such as manufacturer, model, serial number, the method and technique used, the tool used and who verified it. The same fields are a good template for a network device.

Step 4: Decide where to sell

There are several channels, and the right one depends on volume, urgency and how much risk you want to carry yourself.

Channel Where it fits Things to check
Selling directly to a buyer or reseller A small number of devices, or a buyer you already trust Who tests the equipment, how payment works, and who is responsible if a unit arrives dead
An IT asset disposition provider with a resale program Mixed estates where networking is only part of the load Serial-level reporting, how failed units are handled, and the provider's certifications
Trade-in through the vendor or a reseller Planned upgrades Whether the trade-in terms cover your models and the condition they require
Colocation or office closure clean-out Large decommission projects Who de-installs the equipment and removes cabling, and how unsold items are recycled

For the middle option, SERI's R2v3 appendices are a helpful lens. Its guidance says Appendix C applies to facilities that test, repair or refurbish devices for reuse and confirm a defined level of functionality, and that Appendix D applies to specialty electronics where full functionality testing is not feasible, citing network telecom equipment as one example. If a provider will test and resell your networking gear, ask which of these appendices their certification includes. Our explainer on R2v3 certification shows how to read a certificate.

Step 5: Compare offers on more than price

When you receive quotes, line them up on the same terms:

  • Per-unit or lot pricing, and whether the offer is firm or subject to inspection.
  • Testing fees or deductions for units that fail.
  • Shipping and de-installation costs, and who pays.
  • What happens to units that cannot be resold. There should be a documented recycling path.
  • Payment timing, and whether payment is made before or after testing.
  • Reporting. You want a serial-level list of what was received, what was sold and what was recycled.

Do not assume a number. Prices for used network gear depend on the model, condition, demand and licensing position, so collect real quotes rather than guessing from a list price.

Step 6: Finish the paperwork

Before the equipment leaves, make sure you have:

  • a signed bill of sale or agreement listing serial numbers
  • the licensing statement from Step 2
  • your sanitization records from Step 3
  • a handover record showing who collected the equipment and when
  • confirmation that the devices have been removed from your asset register, monitoring and any vendor accounts

If any of the equipment is covered by a lease, a customer contract or a security requirement, check the terms before selling. You may need permission first.

Common mistakes

  • Selling devices with the configuration still on them. Reset and verify.
  • Promising software or support you cannot transfer. Say what the vendor allows and no more.
  • Treating end-of-life equipment as if it were current. Describe its lifecycle status honestly.
  • Skipping the record-keeping. A buyer's questions can arrive months later.
  • Choosing only on the highest quote. A higher offer that deducts heavily after testing can end up lower than a modest firm offer.
