ISR4351-VSEC/K9 Overview
ISR4351-VSEC/K9 Bundle Definition
ISR4351-VSEC/K9 is Cisco's combined UC and Security bundle for the ISR 4351. Cisco's official description includes UC and Security licenses and a PVDM4-64. This differs from ISR4351-V/K9, which is the UC bundle, and ISR4351-SEC/K9, which is the Security bundle.
Router Capacity and Voice Hardware
The underlying ISR 4351 supplies three onboard Gigabit Ethernet interfaces, three NIM slots, two SM-X slots and a 2RU chassis. The platform starts at 200 Mbps aggregate throughput and requires FL-4350-PERF-K9 for 400 Mbps. The included PVDM4-64 is a 64-channel voice DSP module; other voice cards, interface modules and CUBE capacity must be quoted by exact line item.
Purchase Checks
- Verify the UC and Security license status on the delivered chassis.
- Confirm that the PVDM4-64 is physically installed and recognized.
- Review required voice NIMs, CUBE licensing and session capacity separately.
- Confirm throughput licensing, IOS XE release and support status.
