C1121X-8PLTEP Description
The C1121X-8PLTEP is a Cisco 1000 Series Integrated Services Router for branch sites that run LTE or 5G beside their wired WAN circuits. The router pairs a pluggable cellular slot for CAT4 to CAT18 LTE or 5G modules with two Gigabit WAN ports (one RJ-45/SFP combo), eight Gigabit LAN ports, 700 Mbps of SD-WAN IPsec at 512 bytes and 8 GB of DRAM. The 5G modules need Cisco IOS XE 17.9.2a for NSA or 17.12.1a for SA, and LAN PoE requires the optional 150W supply.

Product Performance
Key Features
The cellular slot is not tied to one radio. A CAT4 module is rated at 150 Mbps down and 50 Mbps up in theory, CAT18 at 1200/200 Mbps, and the 5G SA module at 4900/660 Mbps, so a site on a supported release can move from LTE to 5G by swapping the module rather than the router.
The pluggable cellular modules carry two micro (3FF) SIM sockets with Fast SIM failover, except the single-SIM Verizon CAT4 module, and the router switches between the primary and backup link on its own. All modules except the CAT18 and 5G NSA versions also send a dying-gasp message when power is lost.
The X in the model name means 8 GB of DRAM and 8 GB of flash instead of 4 GB. That memory tier supports SD-WAN Advanced Security and hosted applications on the router.
Two wired WAN ports and the cellular module give the router three separate uplinks. The first wired port accepts an RJ-45 cable or an SFP, from 1000BASE-SX on multimode fiber to ZX on single-mode, and the second stays copper for another carrier.
IPsec reaches 600 Mbps with 512-byte packets in autonomous mode, but the SEC license alone allows 50 Mbps. The VPERF license lifts that to 250 Mbps on this eight-port model, and only the HSEC license removes the limit.
One Universal Cisco IOS XE image runs either as an SD-WAN edge under Catalyst SD-WAN Manager, with 200 overlay tunnels, or as a traditional router managed by CLI, WebUI or Cisco DNA Center. With QoS, deep packet inspection and Flexible NetFlow added to IPsec, SD-WAN throughput is 250 Mbps.
Application Scenarios
A construction office or event site with no wired circuit runs its whole WAN over a 5G or CAT18 module, while laptops, printers and cameras connect to the eight LAN ports.
In a retail store, the fiber circuit lands on the combo WAN port and the cellular module stays idle until that circuit fails, keeping card terminals and the store network online.
Small clinics that join a company SD-WAN fabric use the router as their edge, with the 8 GB memory tier supporting SD-WAN Advanced Security for the traffic leaving the site.

C1121X-8PLTEP differs from C1121X-8P only in cellular: it adds a pluggable slot for CAT4 to CAT18 LTE and 5G modules on the same eight LAN ports, 700 Mbps of SD-WAN IPsec and 8 GB of DRAM, while the dongle-only model takes a CAT4 LTE USB dongle and suits sites where wired circuits carry the traffic. Sites with four or fewer LAN devices that still need a pluggable LTE or 5G module can use C1121-4PLTEP, which drops to 450 Mbps of SD-WAN IPsec, 4 GB of DRAM and two PoE or one PoE+ port. C1111-8P has no cellular option and 4 GB of DRAM but forwards up to 1800 Mbps of IPv4, which fits wired-only branches standardized on the 111x range.

Ordering Checklist
- Technology license: IP Base (SL-1K-8P-IPB) is the default; add SL-1K-8P-SEC-SV for zone-based firewall and IPsec VPN, or SL-1K-8P-APP-SV for MPLS and NBAR2. SL-1100-8P licenses apply only to 110x and 111x models.
- IPsec performance license: The SEC license alone allows 50 Mbps of IPsec; FL-VPERF-8P-200-SV raises the limit to 250 Mbps and FL-1100-8P-HSEC removes it. Without HSEC the router cannot reach its 600 Mbps IPsec rating.
- Cellular module: The pluggable is an optional line, so add the module for the carrier region, such as P-LTEA-EA for North America and Europe or P-LTEAP18-GL for CAT18. P-LTEA-EA and P-LTEA-LA also need a firmware selection.
- Antennas: Match the antenna to the module: LTE-ANTM-SMA-D for CAT4 and CAT6, LTE-ANTM2-SMA-D for CAT18, and 5G-ANTM2-SMA-D for CAT7 and 5G modules. Spare P-LTE-VZ, P-LTE-US and P-LTE-GB modules need the antenna selection option.
- Software type: The IOS software version and type is a required selection. A 5G NSA module needs Cisco IOS XE 17.9.2a or later, and a 5G SA module needs 17.12.1a or later.
- 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-RM2-19 for rack mounting, because ACS-1100-RM-19 fits only 111x models. The power cord is a required line on every order.
