ISR4331-AXV/K9 Overview
ISR4331-AXV/K9 Exact Bundle
ISR4331-AXV/K9 combines the ISR 4331 platform with Application Experience, Security and Unified Communications licenses and a PVDM4-32. It must not be reduced to a base ISR4331/K9 or confused with the AX bundle that omits the UC and voice DSP elements.
Router Hardware Profile
The ISR 4331 platform provides three onboard Gigabit Ethernet ports, two NIM slots, one ISC slot and one service-module slot, with 4 GB default DRAM and 4 GB default flash. Cisco publishes 100 Mbps default aggregate throughput and 300 Mbps with the FL-4330-PERF-K9 performance license; boost licensing is a separate entitlement.
Lifecycle and Migration
Cisco ended sale for this PID on November 7, 2023. The last date of support is November 30, 2028, and the lifecycle notice identifies C8200-1N-4T as the migration platform. A migration must separately redesign voice DSP capacity, UC features, security, modules, interfaces and current subscription licensing.
- Confirm PVDM4-32 and APP, SEC and UC entitlement records.
- Inventory NIM and service-module dependencies.
- Do not assume performance or boost licenses are active.
- Plan C8200 migration before the November 2028 support deadline.
