Ethernet uplink supports the following types of configuration in this SCALANCE W release.
● PPPoE
● DHCP
● Static IP
You can use PPPoE for your uplink connectivity in both AP and AP-VPN deployments.
PPPoE is supported only in a single AP deployment.
Note
Uplink redundancy with the PPPoE link is not supported.
When the Ethernet link is up, it is used as a PPPoE or DHCP uplink. After the PPPoE
settings are configured, PPPoE has the highest priority for the uplink connections. The AP
can establish a PPPoE session with a PPPoE server at the ISP and get authenticated using
Password Authentication Protocol (PAP) or the Challenge Handshake Authentication
Protocol (CHAP). Depending upon the request from the PPPoE server, either the PAP or the
CHAP credentials are used for authentication. After configuring PPPoE, reboot the AP for
the configuration to take effect. The PPPoE connection is dialed after the AP comes up. The
PPPoE configuration is checked during AP boot and if the configuration is correct, Ethernet
is used for the uplink connection.
Note
When PPPoE is used, do not configure Dynamic RADIUS Proxy a
nd IP address of the VC.
An SSID created with default VLAN is not supported with PPPoE uplink.
You can also configure an alternate Ethernet uplink to enable uplink failover when an
Ethernet port fails.
