Huawei end of life: EOM, EOFS and EOS explained

The four milestones, in Huawei's own words

Most vendors run two or three lifecycle milestones. Huawei runs four, and the two in the middle are the ones that get misread. These definitions are taken from Huawei's published EOX bulletins and its Product End of Life Policy.

If your inventory has one Huawei date per device and nobody recorded which milestone it came from, it is worth checking. An EOM date filed as an end-of-support date will make an estate look years more urgent than it is, and an EOFS date filed the same way will make it look safer than it is.

Why you probably cannot find the EOS date

Huawei's bulletin library at support.huawei.com is genuinely good: every announcement carries a milestone table and a replacement product table with part numbers on both sides. The problem is which announcements you are allowed to read.

The Switches and WLAN categories together hold 794 lifecycle bulletins, 491 of which concern hardware rather than software releases. On August 21, 2026 we opened 269 of those hardware bulletins and recorded what each one actually contains:

Everything else that opens publishes End of Marketing only. The bulletins titled "EOS Announcement", which are the ones covering current kit like the S5720, S6720 and CloudEngine S5731, are classified at content security level C. Opening one while signed in with an ordinary registered account returns "you do not have the permission to view this information", with an invitation to register a purchased product or upgrade to a partner account.

That is a defensible choice by Huawei, and it is worth knowing before you spend an afternoon looking. It also means any third-party site showing you a confident Huawei end-of-support date is either a partner passing on entitled data or is inferring it, and the two look identical from the outside.

What a complete Huawei bulletin looks like

When a bulletin does carry the full picture, it is the best-structured EOL notice any vendor publishes. Here is a real one, the CloudEngine CE6850-48T6Q-HI, which is public:

Two things to take from it. The gap between EOM and EOS here is five years, but note the word planned: Huawei marks forward-looking EOS dates as provisional, so a date read once and filed forever can move. And the bulletin names the replacement product with part numbers on both sides, which makes the migration conversation concrete in a way most vendors' notices do not.

How to get the EOS date for your own kit

• Ask the partner who sold it to you. This is the fastest route and the one most organisations already have. A Huawei partner can pull the EOX bulletin for a part number in minutes.
• Raise your own account tier. If you bought directly, registering the purchased product against your Uniportal account upgrades you to a product customer and unlocks the bulletins for that product.
• Use Info-Finder's Lifecycle Query once you have access. It gives EOM, EOFS and EOS per product rather than making you read announcements one at a time.
• Record which milestone you captured. Whatever route you use, write down whether the date is EOM, EOFS or EOS next to the date itself. This is the single most useful thing you can do, and it costs nothing at the moment of entry.

How to track Huawei in the meantime

We do not carry Huawei end-of-support dates in our reference data, for the reason set out above: what is public is End of Marketing, and turning a marketing date into a support date by adding five years would be arithmetic presented as a vendor fact. A wrong date in an asset register is worse than a blank one, because a blank invites a question and a wrong date closes it.

So a Huawei device imported into EOL Tracking resolves to No date, and you set the date yourself once you have obtained it. That is the honest behaviour, and it is the same treatment we give MikroTik, which publishes no hardware dates at all. If Huawei is a large part of your estate and you have partner access, the dates you extract are worth the hour: see the EOL policy template for a structure to record them in, and the real risks of running end-of-life equipment for what is at stake on the switches and access points carrying your management network.

New to the terminology? EOL vs EOS vs EOSL untangles the three terms vendors use interchangeably, and Huawei's EOFS milestone is a fourth that almost nobody outside Huawei uses.

Common questions

What is the difference between Huawei EOM, EOFS and EOS?

EOM (End of Marketing) is the last date Huawei accepts orders for the product, including capacity expansion. EOFS (End of Full Support) is the point after which Huawei stops developing new patches, reduces the service categories and SLAs it offers, and stops supplying spare parts under the original part numbers. EOS (End of Service and Support) is the hard stop: after it Huawei provides no service at all for the product, including the service hotline. EOS is the date that belongs in an asset register.

Does Huawei publish end of support dates publicly?

Mostly no. Huawei publishes End of Marketing announcements openly on support.huawei.com, but the bulletins carrying End of Service dates are classified at content security level C, which requires a product-customer or partner Uniportal account. Checked on 21 August 2026: of 269 hardware bulletins opened across the Switches and WLAN categories, 113 rendered without a partner account and only 7 of those contained an EOS date.

Can I work out the Huawei EOS date from the EOM date?

Not reliably, and you should not put a guess in an asset register. Huawei sets EOS per product in the bulletin rather than by a single published interval, and the intervals visible in public bulletins are not consistent. A date derived by adding a fixed number of years to EOM is arithmetic, not a vendor fact, and it will be wrong for part of your estate in whichever direction costs you.

What does EOM (new site) mean on a Huawei bulletin?

It is an earlier milestone than EOM. After the EOM (new site) date Huawei stops selling the product into new sites, while existing sites can still order it for capacity expansion until the full EOM date. It is a warning shot rather than a support deadline.

How do I find the EOS date for a Huawei switch or access point?

Use the Lifecycle Query in Huawei Info-Finder while signed in to a Uniportal account with product-customer or partner entitlement, or ask the partner who sold you the hardware to pull the EOX bulletin. If you bought the equipment directly you can raise your account tier by registering the product against it.
