On the WLAN, a single AP supports a maximum of 30 access STAs or 32 roaming STAs.

When 30 STAs are connected to an AP, the AP ' s SSID is hidden. However, new STAs that know the SSID can still connect to the AP.

If 30 STAs are connected to the AP, the AP allows a maximum of 32 roaming STAs.

If 28 STAs are connected to the AP, the AP allows a maximum of four roaming STAs.

A Layer 2 VXLAN gateway forwards traffic to a VXLAN network and can also be used for Intra-subnet communication on the same VXLAN network.

Layer 2 and Layer 3 VXLAN gateways must maintain VBDIF interfaces. Otherwise, users cannot communicate with each other through these interfaces.

A VBDIF interface is a logical interface created based on a BD. It is similar to a VLANIF interface on a traditional network.

A Layer 3 VXLAN gateway is used for inter-subnet communication on a VXLAN network and communication with external non-VXLAN networks.

It is recommended that network devices at the same physical location be planned into multiple sites. Different sites correspond to different services on the campus network.

Each site can have a tenant administrator to independently manage and maintain its network, or an MSP administrator can be authorized to perform unified network management and O & M for all sites.

An independent branch can be planned as a site based on the physical location, for example, a financial branch of a bank or a campus of a university.

For a midsize campus network, do not plan too many sites. Otherwise, the interconnection between sites and site management will be complex.
