Cisco C1161-8P Full Product Description

1. Short Overview

Suffix Breakdown

• C1161: Flagship high-performance dual-combo Ethernet ISR chassis of the Cisco 116x series, no integrated DSL chipset, purpose-built for pure fiber/copper Metro Ethernet access networks; delivers the highest base forwarding and IPsec throughput among non-X 1000 Series ISRs
• NoX: Base memory variant equipped with 4 GB DRAM + 4 GB flash (X-suffix C1161X-8P upgrades to 8 GB DRAM + 8 GB flash with native IOx edge application hosting capability)
• 8: Integrated 8-port full Gigabit copper LAN switch
• P: PoE power distribution across six of eight LAN ports: 4× IEEE 802.3af PoE (15.4W) + 2× IEEE 802.3at PoE+ (30W), total shared PoE power budget of 120W

Core Differentiators

1. vs compact 4-port C1161-4P: C1161-4P features a 4-port LAN with only 45W PoE budget for micro-branches; C1161-8P expands to 8 LAN ports with 120W PoE capacity to support medium-scale multi-camera and multi-phone unified communications workloads.
2. vs enhanced-memory C1161X-8P: X-suffix models carry 8GB DRAM/8GB flash with IOx edge container hosting for local IoT analytics and offline edge workloads; base C1161-8P ships with standard 4GB/4GB memory without IOx support.
3. vs cellular modular C1161-8PLTEP: LTE variants add front pluggable PIM slots for swappable 4G/5G cellular uplinks; base C1161-8P is wired-only without cellular expansion capability, relying solely on USB LTE dongles for auxiliary backup.
4. vs wireless variant C1161-8PWE: Wireless models integrate internal dual-band 802.11ac Wave2 WLAN AP hardware; C1161-8P omits built-in wireless access point functionality.
5. vs DSL-integrated C1166/C1167 series: C1166/C1167 integrate VDSL2/ADSL2+ DSL modems for analog POTS copper telephone lines; C1161-8P is pure Ethernet architecture without DSL chipset for fiber-first deployments.
6. vs legacy ISR G2 C800 routers: Older C800 platforms run classic IOS without native SD-WAN, limited crypto acceleration, and lack flexible SFP fiber combo uplinks; C1161-8P adopts modern multi-core IOS XE architecture with dedicated hardware VPN offloading for superior encrypted throughputCisco.
