After you save the Layer 2 IPsec VPN service configuration, ExtremeCloud IQ populates the table with randomly generates text strings that VPN clients use to identify themselves to VPN gateways. Extreme Networks VPN clients use these strings like passwords when identifying themselves to the VPN gateway during the Xauth stage between IKE Phase 1 and 2 negotiations.
After you configure a device as a VPN client, ExtremeCloud IQ allocates one of the credentials to it. The name of the VPN client appears in the VPN Client Name column and the entry in the Allocated column changes from false to true. The primary and secondary VPN servers assigned to that client appear in their respective columns.
Next, configure for the VPN service. See Configure Advanced Server Options.
