Peer-to-Peer Client Support

Information About Peer-to-Peer Client Support

Peer-to-peer client support can be applied to individual WLANs, with each client inheriting the peer-to-peer blocking setting of the WLAN to which it is associated. The peer-to-Peer Client Support feature provides a granular control over how traffic is directed. For example, you can choose to have traffic bridged locally within a device, dropped by a device, or forwarded to the upstream VLAN.

Peer-to-peer blocking is supported for clients that are associated with local and central switching WLANs.

Restrictions

  • Peer-to-peer blocking does not apply to multicast traffic.

  • Peer-to-peer blocking is not enabled by default.

  • In FlexConnect, peer-to-peer blocking configuration cannot be applied only to a particular FlexConnect AP or a subset of APs. It is applied to all the FlexConnect APs that broadcast the SSID.

  • FlexConnect central switching clients supports peer-to-peer upstream-forward. However, this is not supported in the FlexConnect local switching. This is treated as peer-to-peer drop and client packets are dropped.

    FlexConnect central switching clients supports peer-to-peer blocking for clients associated with different APs. However, for FlexConnect local switching, this solution targets only clients connected to the same AP. FlexConnect ACLs can be used as a workaround for this limitation.

Configure Peer-to-Peer Client Support

Follow the procedure given below to configure Peer-to-Peer Client Support:

Procedure

  Command or Action Purpose

Step 1

configure terminal

Example:

Device# configure terminal

Enters global configuration mode.

Step 2

wlan profile-name

Example:

Device(config)# wlan wlan1

Enters WLAN configuration submode. The profile-name is the profile name of the configured WLAN.

Step 3

peer-blocking [ drop | forward-upstream]

Example:

Device(config-wlan)# peer-blocking drop

Configures peer to peer blocking parameters. The keywords are as follows:

  • drop—Enables peer-to-peer blocking on the drop action.

  • forward-upstream—No action is taken and forwards packets to the upstream.

Step 4

end

Example:

Device(config)# end

Returns to privileged EXEC mode.

Step 5

show wlan id wlan-id

Example:

Device# show wlan id 12

Displays the details of the selected WLAN.
