C8130-VAI-G2 Description

The C8130-VAI-G2 is a Cisco 8100 Series Secure Router with an embedded VDSL/ADSL modem for small branches on DSL service delivered over ISDN (Annex B/J). The router’s WAN side combines an RJ-11 DSL port, a 1GE RJ-45/SFP combo port and an XGSPON/10G BASE-T port, with two Flex and two LAN gigabit ports, 1.9 Gbps of forwarding, 1.5 Gbps of IPsec and 250 tunnels. SD-WAN is supported from Cisco IOS XE 26.2.1, and the chassis has no expansion bay.

Key Features

Embedded DSL For ISDN-Based Service

The RJ-11 port connects to a built-in VDSL/ADSL modem specified for DSL over ISDN (Annex B/J), so a line of that type terminates on the router itself.

VDSL2 Profiles From 8a To 35b

The modem supports ITU G.993.2 profiles 8a, 8b, 8c, 8d, 12a, 12b, 17a and 35b, and handles ADSL under ITU G.992.1, G.992.3 and G.992.5.

DSL And XGSPON On One Chassis

The RJ-11 DSL port, the XGSPON/10G BASE-T port and the 1GE RJ-45/SFP combo port are all fitted, so a site on DSL can move to passive optical service without changing the router.

280K Routes And 1K VRFs

IPv4 routes stop at 280K, with 1K VRFs and 250 IPsec tunnels, which fits a broadband branch with a simple routing design but not a heavily segmented one.

Fanless At 23W Typical

The fanless 3.5 lb body draws 23W typical from a 66W external supply, which keeps noise and cooling needs out of a shop, a surgery or a small office.

No Expansion Bay

Two Flex ports, two LAN ports, a console port and a USB Type C 3.0 port complete the interface set. The 8100 Series has no NIM or SM bay, and this platform has no cellular module.

Application Scenarios

DSL Branch On ISDN-Built Lines

A branch whose DSL service runs over ISDN-based copper connects the line to the RJ-11 port and terminates it on the embedded modem, with no separate modem in front of the router.

SD-WAN Branch On DSL Access

A branch with DSL access joins a Cisco Catalyst SD-WAN fabric on Cisco IOS XE 26.2.1 or later, with 900 Mbps of SD-WAN throughput available on the router.

Office Cupboard With Gigabit LAN

In an office wiring cupboard, the router feeds a gigabit LAN through its two LAN ports and two Flex ports, and mounts in a rack or on a DIN rail.

C8130-VAI-G2 and C8130-VAP-G2 differ only in the embedded DSL modem: C8130-VAI-G2 supports VDSL/ADSL over ISDN (Annex B/J), while C8130-VAP-G2 supports VDSL/ADSL over POTS (Annex A), and every other row in the table matches. A site on a POTS line therefore needs C8130-VAP-G2. Sites that need six LAN ports, an embedded 5G module with dual nano SIM slots, 5.6 Gbps of forwarding, or 500K IPv4 routes and 4K VRFs should order C8151-CVAI-G2, which keeps the ISDN-side modem, lists 1 Gbps of Threat Protection and supports SD-WAN without the 26.2.1 release that C8130-VAI-G2 needs. It draws 27W typical against 23W and weighs 5.1 lb against 3.5 lb.

Questions & Answers

  • What IPsec throughput is C8130-VAI-G2 rated for?

    C8130-VAI-G2 provides 1.9 Gbps of forwarding throughput and 1.5 Gbps of IPsec throughput, both measured with 512-byte packets. SD-WAN throughput is 900 Mbps with IPsec, QoS, deep packet inspection and Flexible NetFlow enabled, and no Threat Protection throughput is listed for this model.
  • Which external AC adapter is the default order configuration for C8130-VAI-G2?

    The Cisco 8000 Series ordering guide lists the default power supply as the AC adapter PWR-CC1-66WAC. The data sheet rates the external supply at 66W, and typical draw is 23W, so the default adapter covers the router at normal load.
  • From which release is platform-based licensing supported on C8130-VAI-G2?

    Platform-based licensing was introduced for C8130-VAI-G2 in the Cisco IOS XE 26.1.x releases, per the Cisco 8000 Series licensing guide. The licensing tags then apply to the router in autonomous, SD-Routing and SD-WAN controller modes.
  • Which license tags apply to C8130-VAI-G2 in autonomous mode?

    In autonomous mode C8130-VAI-G2 runs under Cisco Routing OS Essentials, with Cisco Routing Advantage available under the tag LIC-ROS-S-A, per the Cisco 8000 Series licensing guide. The Cisco WAN tags are used only when the router is managed in SD-WAN controller mode.
  • Which license tags does C8130-VAI-G2 use in SD-Routing mode?

    In SD-Routing mode C8130-VAI-G2 can run Cisco Routing Advantage (LIC-ROS-S-A), Cisco WAN Essentials (LIC-CSWAN-S-E) or Cisco WAN Advantage (LIC-CSWAN-S-A), per the Cisco 8000 Series licensing guide. The tag chosen sets the feature tier the router is entitled to.
