Uplink Status
Ethernet uplink supports the following types of configuration in this Instant release.
n
PPPoE
n
DHCP
n
Static IP
You can use PPPoE for your uplink connectivity in both IAP and IAP-VPN deployments. PPPoE is supported
only in a single IAP deployment.
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 IAP 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 IAP for the
configuration to take effect. The PPPoE connection is dialed after the IAP comes up. The PPPoE configuration is
checked during IAP boot and if the configuration is correct, Ethernet is used for the uplink connection.
When PPPoE is used, do not configure Dynamic RADIUS Proxy and 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.
