Cisco N6K-C6004EF End of Life & End of Support
Cisco Nexus 6004 EF Switch
Past Last Date of Support (Apr 30, 2022)The Nexus 6004 EF was a 4 slot modular chassis built for high density 10/40G data center aggregation with FCoE support. Cisco's own bulletin lists the Nexus 5696Q as the replacement, but since that platform is itself now end of life, current deployments should move straight to the high density Nexus 9300 (N9K-C93360YC-FX2). Customers should budget for this two step migration path when planning refresh timing.

Running past End-of-Sale or Last Date of Support means no new Cisco TAC, hardware replacement, or security fixes. Uniqcli, an authorized Cisco partner, scopes a like-for-like or better replacement, confirms TAA compliance, accepts the Government Purchase Card (GPC), and plans a low-risk cutover.

Frequently asked questions
When is the Cisco N6K-C6004EF end of life?
Cisco announced End-of-Sale for the N6K-C6004EF effective Apr 30, 2017. The Last Date of Support (LDoS) is Apr 30, 2022, after which Cisco no longer provides support. It is past its last date of support.
What replaces the Cisco N6K-C6004EF?
Cisco's recommended migration is the Cisco Nexus 9300 (N9K-C93360YC-FX2), 96p 1/10/25G, 12p 100G, MACsec. Uniqcli, an authorized Cisco partner, can quote the replacement TAA-compliant and GPC-payable, and help plan the cutover.
Can I still get support for the N6K-C6004EF?
Not from Cisco. The N6K-C6004EF passed its Last Date of Support (Apr 30, 2022), so Cisco TAC, hardware replacement, and SmartNet renewals are no longer available. Independent third-party maintenance can still cover the hardware itself, typically well below OEM renewal rates. Uniqcli can review your install base, confirm coverage, and quote extended support or a refresh side by side.
