Questions & Answers

  • What’s the main role of Cisco C1121X-8P?

    A small branch router with 8x Gigabit LAN and PoE/PoE+ to power IP phones, APs, or cameras. It’s ideal where you need integrated routing, security, and simple LAN power without separate switches.

  • How does C1121X-8P compare to C1121X-8PLTEP?

    Both deliver 8 PoE LAN ports; the LTEP model adds built-in cellular WAN for primary/backup. Choose 8P when you rely on wired WAN only, or add an external LTE modem if needed later.

  • Does it support SD-WAN?

    Yes. It runs IOS XE and can operate in Cisco SD-WAN mode with the proper licenses. You may also run it as a traditional ISR with static/dynamic routing and IPsec VPN.

  • Typical PoE scenarios at the edge?

    Power several phones and an AP directly from the router, keeping a micro-branch simple. For many APs or cameras, pair with a dedicated PoE access switch downstream.

  • How can I harden the LAN side?

    Use VLAN segmentation, 802.1X/MAB, DHCP snooping, and ACLs. Apply zone-based firewall on routed interfaces and terminate IPsec tunnels for secure transport.

  • Is there a built-in GUI for quick setup?

    Yes. A web-based device manager is available for basic provisioning and monitoring. CLI/NETCONF/RESTCONF provide advanced programmable control when standardization is required.

  • What are good deployment examples?

    Retail tills, kiosks, and small offices where one box handles WAN, routing, security, and PoE for a few powered endpoints.

  • Migration path if PoE demand grows?

    Add a Catalyst PoE switch on a trunk, or move to a higher-port ISR/Catalyst platform while reusing existing configuration templates.
