Service Requirements

The hotel wants to provide guests with convenient network access services so that guests only need to enter a character string on the login page for access authentication without having to enter their user names and passwords. Guests are allowed network access after being authenticated successfully. Considering that the hotel scale is small, built-in Portal access code authentication can meet the preceding requirement and local authentication can be used.

Networking Requirements

AC networking mode: Layer 2 bypass mode
DHCP deployment mode:
- The AC functions as a DHCP server to assign IP addresses to APs.
- The aggregation switch (SwitchB) functions as a DHCP server to assign IP addresses to STAs.
Service data forwarding mode: tunnel forwarding
Authentication mode: Built-in Portal access code authentication
Security policy: open

Configuration Notes

No ACK mechanism is provided for multicast packet transmission on air interfaces. In addition, wireless links are unstable. To ensure stable transmission of multicast packets, they are usually sent at low rates. If a large number of such multicast packets are sent from the network side, the air interfaces may be congested. You are advised to configure multicast packet suppression to reduce impact of a large number of low-rate multicast packets on the wireless network. Exercise caution when configuring the rate limit; otherwise, the multicast services may be affected.
- In direct forwarding mode, you are advised to configure multicast packet suppression on switch interfaces connected to APs.
- In tunnel forwarding mode, you are advised to configure multicast packet suppression in traffic profiles of the AC.
For details on how to configure traffic suppression, see How Do I Configure Multicast Packet Suppression to Reduce Impact of a Large Number of Low-Rate Multicast Packets on the Wireless Network?.
Configure port isolation on the interfaces of the device directly connected to APs. If port isolation is not configured and direct forwarding is used, a large number of unnecessary broadcast packets may be generated in the VLAN, blocking the network and degrading user experience.
In tunnel forwarding mode, the management VLAN and service VLAN cannot be the same. Only packets from the management VLAN are transmitted between the AC and APs. Packets from the service VLAN are not allowed between the AC and APs.
