C1112-8P Description

The C1112-8P is a Cisco 1000 Series Integrated Services Router for small branch offices whose WAN service arrives over a G.FAST or VDSL2 copper line. The router pairs a Gigabit RJ-45/SFP combo WAN port with a G.FAST DSL port (Annex B), adds eight Gigabit LAN ports, and runs up to 600 Mbps of IPsec at 512 bytes on 4 GB of DRAM. The SEC license alone caps encrypted traffic at 50 Mbps, and the full IPsec rate needs the HSEC license.

Key Features

G.FAST And VDSL2 On The Second WAN Port

The second WAN port is a DSL interface rather than Ethernet, so the router terminates a copper telephone-pair circuit without an external modem. It runs G.FAST with spectrum up to 106 MHz, VDSL2 up to profile 35b, and stays compatible with ADSL2/2+ lines.

Copper Or Fiber On The Combo Port

The Gigabit combo port accepts an RJ-45 cable or an SFP. Supported optics include GLC-SX-MMD for multimode runs and GLC-LH-SMD, GLC-EX-SMD and GLC-ZX-SMD for single-mode fiber, so a fiber handoff can sit beside the DSL line.

PoE On Up To Four LAN Ports

Powering phones or cameras from the LAN switch needs the optional ISR-1100-POE4 adapter and its 150W supply. With it installed, four ports deliver 802.3af PoE, or two ports deliver 802.3at PoE+.

Encryption Speed Set By License

Hardware IPsec reaches 600 Mbps at 512 bytes in autonomous mode, but licensing decides how much of it is usable. SEC allows 50 Mbps, FL-VPERF-8P-200 lifts the ceiling to 250 Mbps, and the HSEC license removes the limit.

SD-WAN Edge Or Autonomous Router

One Universal IOS XE image runs the router under Catalyst SD-WAN Manager or as a CLI, WebUI and Cisco DNA Center managed device. In SD-WAN mode it carries 200 overlay tunnels, and IPsec drops from 650 Mbps to 250 Mbps once QoS, deep packet inspection and Flexible NetFlow are applied.

Routing Tables Sized For 4 GB

With 4 GB of DRAM, autonomous mode holds 280K IPv4 and 260K IPv6 routes, 100K NAT sessions and 1K VRFs.

Application Scenarios

Branch On A G.FAST Copper Line

Where the carrier reaches a small office only over telephone copper, the router brings the G.FAST or VDSL2 service straight into its DSL port and routes it to the eight wired desks and devices on the LAN.

SD-WAN Site With Two Transports

A retail branch in an SD-WAN fabric uses the DSL circuit as one transport and a fiber or Ethernet service on the combo port as the other, with both tunnels managed from Catalyst SD-WAN Manager.

Front Office With Powered Phones

In a reception area or small clinic, up to four IP phones, or two PoE+ wireless access points, draw power directly from the router’s LAN ports once the PoE adapter is fitted.

C1112-8P and C1111-8P share eight LAN ports, 600 Mbps of IPsec and 1800 Mbps of forwarding, but C1112-8P has a G.FAST DSL port (Annex B) where C1111-8P has a second copper Gigabit WAN port. Sites whose two circuits both arrive as Ethernet or fiber need C1111-8P, since C1112-8P has only one Ethernet WAN port. A G.FAST line provisioned as Annex A calls for C1113-8P, which keeps the same throughput and 4 GB of memory. Branches that need SD-WAN IPsec up to 700 Mbps, 8 GB of DRAM and flash, or a CAT4 LTE USB dongle for backup move to C1121X-8P, which has no DSL port and forwards up to 1600 Mbps.

Ordering Checklist

  • Technology license: IP Base (SL-1100-8P-IPB) is the default; add SL-1100-8P-SEC for zone-based firewall, IPsec VPN and DMVPN, or SL-1100-8P-APP for MPLS and NBAR2. SL-1K licenses fit 112x models, not this router.
  • IPsec performance license: Add FL-1100-8P-HSEC to remove the encryption limit, or FL-VPERF-8P-200 for a 250 Mbps ceiling. With SEC alone, tunnels stop at 50 Mbps.
  • Software type: The IOS software version and type is a required selection, and the router needs Cisco IOS XE 16.8.1 or later.
  • DSL firmware: The xDSL firmware option is a required selection for this DSL model; B2pvfbH043j is the G.FAST Annex B image.
  • PoE supply: Add ISR-1100-POE4 when LAN ports must power phones or access points; it replaces the standard 66W adapter with a 150W supply. Without it no LAN port supplies power.
  • Rack kit and power cord: Order ACS-1100-RM-19 for rack mounting, because ACS-1100-RM2-19 fits 112x models. The power cord is a required line on every order.

Questions & Answers

  • What throughput does C1112-8P with 512-byte packets?

    C1112-8P forwards IPv4 traffic at up to 1,800 Mbps with 512-byte packets. IPsec reaches up to 600 Mbps in autonomous mode, and SD-WAN IPsec reaches up to 650 Mbps, falling to 250 Mbps once QoS, deep packet inspection and Flexible NetFlow are applied.
  • Which license does C1112-8P need for firewall and VPN?

    C1112-8P needs SL-1100-8P-SEC for zone-based firewall and IPsec VPN on top of its default IP Base package, SL-1100-8P-IPB. SEC alone allows 50 Mbps of encrypted traffic; FL-VPERF-8P-200 lifts the ceiling to 250 Mbps and FL-1100-8P-HSEC removes it.
  • Does C1112-8P include an embedded Wi-Fi access point?

    No. C1112-8P has no 802.11ac access point and no cellular interface. The Wi-Fi regulatory domain listed for the C1112 family, domain E, applies only to the W variants, so a site that needs on-board Wi-Fi must order a W model.
  • What is the maximum power consumption of C1112-8P, excluding external power supply loss?

    C1112-8P draws up to 35.3W at maximum, excluding loss in the external power supply, per the Cisco ISR 1000 Series data sheet. This is the draw of the router itself with the standard 66W adapter, so a UPS for a branch rack should be sized from the adapter input rather than from this figure alone.
  • Which EMC emission and immunity standards is C1112-8P listed against?

    C1112-8P is listed against EN55022/CISPR22, CFR 47 Part 15, ICES003, VCCI-V-3, AS/NZS CISPR22 and CNS13438 for emissions, per the Cisco ISR 1000 Series data sheet. For immunity it lists EN55024/CISPR24 and EN61000-4-2 through -6 plus -11. Both lists also include EN300-386, so one test report covers compliance questions for either direction.
  • What operating temperature range applies to C1112-8P at sea level?

    C1112-8P operates from 0 to 40°C at sea level, and the upper limit derates by 1°C per 1000 ft above sea level. Humidity must stay noncondensing, so a closet without cooling or ventilation needs a site check before the router goes in.
