Cisco issues blizzard of end-of-life notices for Nexus 3K and 7K switches

Service options decline starting next year... so there may be a Nexus 9K switch in your future

Cisco has in recent days issued a blizzard of end-of-life and end-of-sale announcement for switches in its Nexus 3000 and Nexus 7000 ranges.

By The Register’s count, the networking giant has announced that the 18 devices, listed below, across the ranges will soon be sent to the knacker's yard.

The initial batch of notices advised users that the listed devices would not be sold after late August 2021, with shipments to end in November of the same year and support services dwindling as of August 2022. November 2025 was set as the last date on which a service contract could be renewed.

However, Chipzilla has since updated a handful of the notices and extended some of the deadlines mentioned above by as much as 18 months. You can find the 3K notices here and the 7K notices here. The last day of hardware support will be sometime in 2026 or 2027, depending on the model.

Cisco constantly retires products, though The Register has not seen quite so many end-of-life announcements land in such a short period of time. We asked Chipzilla what’s up.

A switch with just 49 ns latency? What strange magic is this?


A spokesperson told us that it’s business as usual.

“Many of the models referenced in the announcements were introduced over 10 years ago and were replaced by newer models in the Nexus 9000 series switches,” we were told. Newer models from the 9K range are offered “as migration options for the Nexus 3000 and Nexus 7000 products included in the EoL announcements.”

The spokesperson also pointed out that the Nexus 3K series continues to evolve, with new 3500-series devices infused with tech drawn from Australian company Exablaze that aimed its wares at high-frequency traders and other latency-intolerant users.

“We continue to invest in the portfolio,” Cisco said.

Switches are almost commodities these days and, in many applications, can happily chug along for years without much need for intervention or network redesign. It's entirely possible that users could keep the 3K and 7K devices Cisco is killing off in production until Chipzilla stops providing security updates. Cisco would rather you don’t adopt that mindset and instead take up its intent-based networking push that is more-fully-supported in its more recent products.

    In-brief Governments around the world should pass intellectual property laws that grant rights to AI systems, two academics at the University of New South Wales in Australia argued.

    Alexandra George, and Toby Walsh, professors of law and AI, respectively, believe failing to recognize machines as inventors could have long-lasting impacts on economies and societies. 

    "If courts and governments decide that AI-made inventions cannot be patented, the implications could be huge," they wrote in a comment article published in Nature. "Funders and businesses would be less incentivized to pursue useful research using AI inventors when a return on their investment could be limited. Society could miss out on the development of worthwhile and life-saving inventions."

  • Stolen university credentials up for sale by Russian crooks, FBI warns

    Russian crooks are selling network credentials and virtual private network access for a "multitude" of US universities and colleges on criminal marketplaces, according to the FBI.

    According to a warning issued on Thursday, these stolen credentials sell for thousands of dollars on both dark web and public internet forums, and could lead to subsequent cyberattacks against individual employees or the schools themselves.

    "The exposure of usernames and passwords can lead to brute force credential stuffing computer network attacks, whereby attackers attempt logins across various internet sites or exploit them for subsequent cyber attacks as criminal actors take advantage of users recycling the same credentials across multiple accounts, internet sites, and services," the Feds' alert [PDF] said.
