ISR4351-AXV/K9 combines Application, Security and Unified Communications licenses on the ISR 4351 platform. Cisco's exact official bundle description also names the PVDM4-64. Buyers should therefore validate four separate elements: the chassis identity, all three license families, the DSP module and any additional ordered interfaces.
The 2RU ISR 4351 provides three onboard Gigabit Ethernet interfaces, three NIM slots and two SM-X slots. Its default aggregate throughput is 200 Mbps, with 400 Mbps dependent on the FL-4350-PERF-K9 license. AXV licensing does not replace the need to verify the performance license.
