ISR4321-VSEC/K9 is the Cisco ISR 4321 bundle that includes the UC and SEC licences. The 4321 has two onboard 10/100/1000 WAN/LAN ports, two NIM slots, no enhanced service-module slot and one external USB 2.0 port. Default aggregate throughput is 50 Mbps. A performance licence raises it to 100 Mbps and a boost licence to 1.5 Gbps on CEF-only traffic.
Default memory is 4 GB of DRAM, with 8 GB the maximum on the 4321, and 4 GB of flash, expandable to 8 GB. Power comes from an external AC or PoE supply. Typical consumption with no modules is 36 W and the maximum with the AC supply is 125 W. The chassis is 1RU and measures 1.75 x 14.55 x 11.60 in (44.55 x 369.57 x 294.64 mm).
Cisco announced end-of-sale on November 7, 2022; the end-of-sale date is November 7, 2023 and the last date of support is November 30, 2028. Cisco names the C8200-1N-4T Catalyst router as the replacement for ISR4321-VSEC/K9.
Larger ISR models are in the Cisco routers range, for example the ISR4331/K9.
