How to Check Cisco EOL Status Online

Aug 10 , 2026 5

TL;DR: Check Cisco EOL status in four steps: find the official EOL bulletin on cisco.com for your product family, confirm the exact PID and serial on the device (show version, show inventory), read the milestone dates, and decide with those dates in hand. This page walks through each step and links the brand-by-brand EOL lists we maintain.

Step 1: Find the Official EOL Bulletin

Cisco publishes an end-of-life bulletin for every retired product. Use the Cisco End-of-Life Products search and enter the product family (for example, Catalyst 3850) or the full part number. The bulletin contains the complete milestone table: end of sale, end of new service attachment, end of security updates and end of support. Bookmark the bulletin — it is the authoritative answer for any model question.

Step 2: Confirm the PID and Serial on the Device

The EOL bulletin applies to the product family, so you need the exact PID of your unit. On any IOS or IOS-XE device:

show version
show inventory

show inventory lists each module with its PID and serial number — record them both. If the unit is not powered on, read the label on the chassis; every Cisco product carries a PID and SN. With the PID in hand, search the EOL tool again to catch sub-model differences (for example, a 2960-X versus a 2960-XR).

Step 3: Read the Milestone Timeline

Cisco EOL bulletins use a standard set of dates. The three that matter to buyers:

A useful buying rule: a unit is "recently EOL" between end of sale and end of support — still fully supported by Cisco, and usually the sweet spot for pre-owned purchases. Long after end of support, prices drop further but the risk profile changes completely.

Step 4: Check the Serial Number for Contract Status

For a specific unit, use the serial-number lookup in the Cisco Support portal. It shows whether the unit ever had SMARTnet coverage and its current contract state. This matters less for EOL status (which is family-based) and more for confidence in the unit's service history — a serial with a long coverage trail is a good sign.

What EOL Status Means for Your Buying Decision

• Pre-EOL or recently EOL: the best used-buying window; expect full functionality and a meaningful price cut.
• End of support passed: fine for lab, DR or short bridge duty — with a seller warranty and documented testing.
• EOL for many years: only for spares of an existing fleet you refuse to migrate.

Whichever tier you land in, buy from a seller who documents testing and offers a warranty, because after end of support, the seller's testing is your only protection.

Brand-by-Brand EOL Reference Lists

We maintain model-level EOL lists for the brands our customers run. Start with the Cisco lists, then check the other vendors you operate:

• Cisco EOL switches: complete list
• Catalyst 4500 and 6500 migration guide
• Juniper EOL equipment list
• FortiGate EOL list
• Huawei EOL network equipment list

If the model you need is not on a list yet, run the two checks above — the official bulletin plus the on-device PID — and you will have your answer in five minutes.

FAQ

Q: Where do I check Cisco end-of-life dates?

A: Use the Cisco End-of-Life Products search on cisco.com: type the product family or exact part number and the bulletin shows every milestone date (end of sale, end of support). No login is required for basic lookups.

Q: How do I check EOL status for a specific serial number?

A: Enter the serial in the Cisco Support serial-number lookup tool. It returns warranty and contract status, which tells you whether the unit was covered; EOL status itself is tied to the product family, not the individual serial.

Q: What does end of support mean for my switch?

A: It means Cisco will not provide new software releases, security patches or replacement parts for that product. The hardware keeps running, but every future failure is an out-of-support event.

Q: Can I run show version to check EOL?

A: Partially. show version shows the IOS version and model; show inventory lists the PID and serial. You then look up that PID in the Cisco EOL tool to get official dates. The on-device commands confirm what you actually have.

Q: Are EOL switches still safe to use?

A: They run, but they accumulate unpatched vulnerabilities over time. For internet-facing or sensitive segments, migrate; for isolated lab or management traffic, an EOL unit with a warranty is a reasonable stopgap.

Q: What is the difference between end of sale and end of support?

A: End of sale is the last date you can order the product new; end of support is the last date Cisco will provide maintenance and fixes. Between the two dates the product is still fully supported — a good window for buying used units with active support.
