Tunnel Termination Services
The Tunnel Termination Service is a service that is used by APs to request L2TPv3 tunnel connection. The service is automatically installed once Mist Edge is fully configured.
In the Mist portal, Tunnel Termination Services field autopopulates in a few scenarios.
When you configure a new Mist Edge device, you update the Tunnel IP Configuration pane. This includes an IP address, netmask, and gateway information. In the example here, the Mist Edge device, test_1 has an IP address of 10.1.2.1.
Go to Mist Edges > Mist Edge Clusters pane and select Create Cluster. You can add the newly created Mist Edge device to the Cluster.
When you add this Mist Edge device to Cluster, the IP address is autopopulated in the Hostnames/ IPs field in the Tunnel Termination Services pane. In this example, the IP address 10.1.2.1 of Mist Edge device, test_1 auto populates in the Tunnel Termination Services pane of the Cluster, Test_Cluster.
If you edit the IP address in the Tunnel IP Configuration pane present in the Mist Edge inventory page, the IP address in the Tunnel Termination Services pane of the Mist Edge Clusters page autopopulates.
In this example, IP address of Mist Edge device, test_1 in the Mist Edge Inventory is edited to 10.1.2.3. Notice that the IP address autopopulates in the Tunnel Termination Services pane of, Test_Cluster in the Mist Edge Clusters page.
In a teleworker use case, where an AP must connect to a Mist Edge through firewall, you require an additional external IP address. You can enter the external IP address in the Hostnames/ IPs field present in the Tunnel Termination Services pane. You must separate the addresses with commas.
In this example, add an external IP address 172.10.1.1 in the Hostnames/ IPs field of Test_Cluster. Notice that the IP address of Mist Edge device, test_1, which belongs to the Test_Cluster is not impacted.
When you add any additional IP address in the Tunnel Termination Services pane of a cluster, there is no impact on the IP address of Mist Edge device, which belongs to the cluster.
When you edit the IP address in the Mist Edge page, the edited IP address autopopulates in the Hostnames/ IPs field present in the Tunnel Termination Services pane of the Mist Edge Clusters page.
In this example, the IP address of Mist Edge device test_1, is edited from 10.1.2.3 to 10.1.2.4. You can notice that the IP address in the Hostnames/ IPs field of Test_Cluster autopopulates with the edited IP address, 10.1.2.4.
Ensure that the IP addresses are correct before you proceed.
