Frequently asked questions

When is the Cisco CISCO1921/K9 end of life?

Cisco announced End-of-Sale for the CISCO1921/K9 effective Sep 29, 2018. The Last Date of Support (LDoS) is Sep 30, 2023, after which Cisco no longer provides support. It is past its last date of support.

What replaces the Cisco CISCO1921/K9?

Cisco's recommended migration is the Cisco ISR 4221 (2GE, 2NIM, 8G Flash, 4G DRAM, IP Base). 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 CISCO1921/K9?

Not from Cisco. The CISCO1921/K9 passed its Last Date of Support (Sep 30, 2023), 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.
