ISR4321-SEC/K9 Overview
Start with the ISR4321 SEC bundle identity
The manufacturer's exact row describes ISR4321-SEC/K9 as a router bundle with a SEC license. Cisco lists AX, V and VSEC bundles separately. Specify the required entitlement and delivered hardware configuration on the quotation; the SEC model name alone does not demonstrate every application, voice or performance option.
Verify the active performance license
Cisco publishes 50 Mbps as the ISR4321 default aggregate throughput. The separate FL-4320-PERF-K9 performance license raises that tier to 100 Mbps. These aggregate tiers should not be substituted for a measured result with every service enabled. Inspect the running image and active entitlement, then assess the actual workload.
Count logical interfaces before choosing media
The platform has two onboard Gigabit Ethernet interfaces and two NIM slots. Its connector choices should not be summed as extra independent WAN interfaces. The data sheet lists external power configurations; check the adapter and the planned module load for the offered unit. Record installed modules separately from empty expansion capacity.
Use the 4321-specific replacement recommendation
Cisco's lifecycle row names C8200-1N-4T for this exact SEC bundle, which differs from the C8200L recommendation for the 4221. Sales ended November 7, 2023, and the final hardware support date is November 30, 2028 under the notice's entitlement conditions. Plan the replacement licensing and module compatibility before migrating the configuration.
