Wireless Guest Access

Wireless guest access

Wireless guest access is a network security feature that

  • provides internet access to guests in a secure and accountable manner

  • uses the enterprise's existing wireless and wired infrastructure to the maximum extent, and

  • reduces the cost and complexity of building a physical overlay network.

Wireless guest access architecture and components

The Wireless Guest Access solution comprises of two controllers - a Guest Foreign and a Guest Anchor. An administrator can limit bandwidth and shape the guest traffic to avoid impacting the performance of the internal network.


Note

  • When a client joins through a capwap tunnel from an AP, the RADIUS NAS-Port-Type is set as "wireless 802.11". Here, Point of Attachment (PoA) and Point of Presence (PoP) is the same.

  • When a client joins through a mobility tunnel, the RADIUS NAS-Port-Type is set as "virtual". Here, PoA is the Foreign controller and PoP is the Anchor controller as the client is anchored. For information on the standard types, see the following link:

    https://www.iana.org/assignments/radius-types/radius-types.xhtml#radius-types-13

Wireless Guest Access feature comprises these functions:

  • Guest Anchor controller is the point of presence for a client.

  • Guest Anchor Controller provides internal security by forwarding the traffic from a guest client to a Cisco Wireless Controller in the demilitarized zone (DMZ) network through the anchor controller.

  • Guest Foreign controller is the point of attachment of the client.

  • Guest Foreign Controller is a dedicated guest WLAN or SSID and is implemented throughout the campus wireless network wherever guest access is required. A WLAN with mobility anchor (guest controller) configured on it identifies the guest WLAN.

  • Guest traffic segregation implements Layer 2 or Layer 3 techniques across the campus network to restrict the locations where guests are allowed.

  • Guest user-level QoS is used for rate limiting and shaping, although it is widely implemented to restrict the bandwidth usage for a guest user.

  • Access control involves using embedded access control functionality within the campus network, or implementing an external platform to control guest access to the Internet from the enterprise network.

  • Authentication and authorization of guests that are based on variables, including date, duration, and bandwidth.

  • An audit mechanism to track who is currently using, or has used, the network.

  • A wider coverage is provided by including areas such as lobbies and other common areas that are otherwise not wired for network connectivity.

  • The need for designated guest access areas or rooms is removed.

Foreign map

A foreign map is a guest access feature that

  • supports guest access using Policy Profile and WLAN Profile configuration models in the controller

  • is achieved with policy profile and WLAN profile config model, and

  • configures two different WLAN profiles on two Guest Foreigns where seamless roaming is not allowed between them.

Foreign map configuration

Foreign Map support in Cisco Catalyst 9800 Series Wireless Controller is achieved with the policy profile and WLAN profile configuration model.

Foreign map commands

  • Guest Foreign commands:

    • Foreign1: wlanProf1 PolicyProf1

    • Foreign2: wlanProf2 PolicyProf2

  • Guest Anchor commands:

    • wlanProf1, wlanProf2

    • PolicyProf1: Vlan100 - subnet1

    • PolicyProf2: Vlan200 - subnet2

Foreign map roaming

Configure two different WLAN profiles on the two Guest Foreigns and seamless roaming is not allowed between them. This is expected configuration. However, seamless roaming is allowed if the same WLAN profile is configured on two Guest Foreigns, but it prevents Foreign Map feature from working.

Wireless Guest Access: Use Cases

The wireless guest access feature can be used to meet different requirements. Some of the possibilities are shared here.

Scenario One: Providing Secured Network Access During Company Merger

This feature can be configured to provide employees of company A who are visiting company B to access company A resources on company B network securely.

Scenario Two: Shared Services over Existing Setup

Using this feature, you can provide multiple services using multiple vendors piggy backing on the existing network. A company can provide services on an SSID which is anchored on the existing controller. This is while the existing service continues to serve over the same controller and network.

Guidelines for wireless guest access

Match the security profiles under WLAN on both Guest Foreign, and Guest Anchor.

  • Match the policy profile attributes such as NAC and AAA Override on both Guest Foreign, and Guest Anchor controllers.

  • On Export Anchor, the WLAN profile name and Policy profile name is chosen when a client joins at runtime and the same should match with the Guest Foreign controller.

Recommendation: troubleshooting IPv6

When a guest export client cannot get a routable IPv6 address through SLAAC or cannot pass traffic when the IPv6 address is learned through DHCPv6, you can use these workarounds:

  • On IPv6 Routers: You can work around the RA multicast to unicast conversion by modifying behavior on the IPv6 gateway. Depending on the product, this may be the default behavior or may require configuration.

  • On Cisco IPv6 Routers: Configure unicast RA depending on your platform.

  • On non-Cisco IPv6 Routers: If non-Cisco network devices do not support configuration command to enable solicited unicast RA then a work around does not exist.

For Cisco IPv6 Routers:

  • Cisco Nexus platform: Has solicited unicast RA enabled by default to help with wireless deployment.

  • Cisco IOS-XE platform: Use the following configuration command to turn on unicast RA to help with wireless deployment:

    ipv6 nd ra solicited unicast

Load balancing among multiple guest controllers

Load balancing among multiple guest controllers is a network configuration feature that

  • distributes large guest client volumes across up to 72 controllers for a single export foreign guest WLAN configuration

  • supports priority-based anchor configuration with primary anchors (priority 1,3) and backup anchors for failure scenarios, and

  • automatically handles failover by disconnecting clients from failed primary anchors and redirecting them to secondary anchors.

Configuration and failover behavior

To configure mobility guest controllers, use mobility anchor ip address .

You can specify primary anchors with priority (1,3) and choose another anchor as backup in case of failure.

In a multi-anchor scenario, when the primary anchor goes down, the clients get disconnected from the primary anchor and joins the secondary anchor.

When the highest priority anchor goes down before the keep-alive timeout completes, the export anchor request for new clients fails, and Foreign selects the next highest priority Anchor in the list to export the clients.

Configure mobility tunnel for guest access (GUI)
