PRODUCT DESCRIPTION
Cisco ISR 1100 8 Ports Dual GE WAN Ethernet Router (C1111-8P) — Local Warranty
IOS XE branch router
The Cisco C1111-8P is a Cisco 1000 Series Integrated Services Router (ISR 1100) for small branches and remote offices. It runs Cisco IOS XE, operating either as a traditional (autonomous) router or as a Cisco SD-WAN edge device.
Dual Gigabit WAN, 8-port LAN
Two WAN interfaces are provided: one Gigabit Ethernet copper/SFP combo port and one Gigabit Ethernet copper port. An integrated 8-port Gigabit Ethernet LAN switch connects local devices without a separate switch.
Higher throughput than the 4-port model
Cisco rates the C1111-8P at up to 1,800 Mbps IPv4 forwarding and up to 600 Mbps IPsec in autonomous mode, and up to 650 Mbps IPsec (512-byte packets) in SD-WAN mode.
4 GB memory
The base model has 4 GB DRAM and 4 GB flash, and Cisco lists maximum power consumption of 19.2 W excluding power supply losses.
Optional PoE
Cisco offers optional PoE/PoE+ on the LAN ports (4 PoE or 2 PoE+), which requires the 150 W power supply instead of the standard 66 W supply.
