ANSI: Operating in ADSL2/2+ mode, as defined in ITU G.991.1, G.992.3, and G992.5, Annex A and Annex M, and in VDSL2 mode, as defined in ITU-T G993.2. VDSL2: Operate in VDSL2 mode, as defined in ITU-T G.993.2, which uses frequencies of up to 30 MHz to provide a downstream rate of 200 Mbps and an upstream rate of 100 Mbps.
   SRA	Enabled by default. Click No to disable seamless rate adaptation on the interface. SRA adjusts the line rate based on current line conditions.

2. Configure Ethernet.

   Table 2. Ethernet

   Parameter Name	Description
   Ethernet Interface Name *	Enter the name of an ethernet interface. For IOS XE routers, you must spell out the interface names completely (for example, GigabitEthernet0/0/0).
   Description	Enter a description for the interface.
   VLAN ID	Enter the VLAN identifier of the Ethernet interface.

3. Configure Tunnel.

   Table 3. Tunnel

   Parameter Name	Description
   Tunnel Interface
   Per Tunnel QoS	Enable per tunnel QoS and choose from the following values to configure hub-to-spoke network topologies: Spoke Hub
   Color	Select a color for the TLOC.
   Color Description	Minimum supported release: Cisco Catalyst SD-WAN Manager Release 20.18.1 Enter a description associated to the TLOC color.
   Groups	Enter the list of groups in the field.
   Exclude Controller Group List	Set the Cisco SD-WAN Controllers that the tunnel interface is not allowed to connect to. Range: 0 through 100
   Maximum Control Connections	Specify the maximum number of Cisco SD-WAN Controllers that the WAN tunnel interface can connect to. To have the tunnel establish no control connections, set the number to 0. Range: 0 through 8 Default: 2
   Cisco SD-WAN Manager Connection Preference	Set the preference for using a tunnel interface to exchange control traffic with Cisco SD-WAN Manager. Range: 0 through 8 Default: 5
   Tunnel TCP MSS	TCP MSS affects any packet that contains an initial TCP header that flows through the router. When configured, TCP MSS is examined against the MSS exchanged in the three-way handshake. The MSS in the header is lowered if the configured TCP MSS setting is lower than the MSS in the header. If the MSS header value is already lower than the TCP MSS, the packets flow through unmodified. The host at the end of the tunnel uses the lower setting of the two hosts. To configure TCP MSS, provide a value that is 40 bytes lower than the minimum path MTU. Specify the MSS of TPC SYN packets passing through the Cisco IOS XE Catalyst SD-WAN. By default, the MSS is dynamically adjusted based on the interface or tunnel MTU such that TCP SYN packets are never fragmented. Range: 552 through 1460 bytes Default: None
   Border	From the drop-down list, select Global. Click On to set TLOC as border TLOC.
   Validator As Stun Server	Click On to enable Session Traversal Utilities for NAT (STUN) to allow the tunnel interface to discover its public IP address and port number when the router is located behind a NAT.
   Full Port Hop	Minimum release: Cisco IOS XE Catalyst SD-WAN Release 17.18.1a Enable full port hopping at the TLOC level to allow devices to establish connections with controllers by switching to the next port if the current port is blocked or non-functional. Default: Disabled
   Port Hop	From the drop-down list, select Global. Click Off to allow port hopping on tunnel interface. Default: On, which disallows port hopping on tunnel interface. Starting from Cisco IOS XE Catalyst SD-WAN Release 17.18.1a, this field is deprecated. Instead use the Full Port Hop option. See the Full Port Hop field.
   Low-Bandwidth Link	Click On to set the tunnel interface as a low-bandwidth link. Default: Off
   Clear-Dont-Fragment	Configure Clear-Dont-Fragment for packets that arrive at an interface that has Don't Fragment configured. If these packets are larger than what MTU allows, they are dropped. If you clear the Don't Fragment bit, the packets are fragmented and sent. Click On to clear the Dont Fragment bit in the IPv4 packet header for packets being transmitted out of the interface. When the Dont Fragment bit is cleared, the router fragments packets larger than the MTU of the interface before sending the packets. Note Clear-Dont-Fragment clears the Dont Fragment bit and the Dont Fragment bit is set. For packets not requiring fragmentation, the Dont Fragment bit is not affected.
   Network Broadcast	From the drop-down list, select Global. Click On to accept and respond to network-prefix-directed broadcasts. Enable this parameter only if the Directed Broadcast is enabled on the LAN interface feature template. Default: Off
   Carrier	From the drop-down list, select Globaland select the carrier name or private network identifier to associate with the tunnel. Values: carrier1, carrier2, carrier3, carrier4, carrier5, carrier6, carrier7, carrier8, default. Default: default
   Bind Loopback Tunnel	Enter the name of a physical interface to bind to a loopback interface. The interface name has the following format: ge slot/port
   NAT Refresh Interval	Set the interval between NAT refresh packets sent on a DTLS or TLS WAN transport connection. Range: 1 through 60 seconds Default: 5 seconds
   Hello Interval	Enter the interval between Hello packets sent on a DTLS or TLS WAN transport connection. Range: 100 through 10000 milliseconds Default: 1000 milliseconds (1 second)
   Hello Tolerance	Enter the time to wait for a Hello packet on a DTLS or TLS WAN transport connection before declaring that transport tunnel to be down. Range: 12 through 60 seconds. Default: 12 seconds. The default hello interval is 1000 milliseconds, and it can be a time in the range 100 through 600000 milliseconds (10 minutes). The default hello tolerance is 12 seconds, and it can be a time in the range 12 through 600 seconds (10 minutes). To reduce outgoing control packets on a TLOC, it is recommended that on the tunnel interface you set the hello interval to 60000 milliseconds (10 minutes) and the hello tolerance to 600 seconds (10 minutes) and include the no track-transport disable regular checking of the DTLS connection between the edge device and the controller. For a tunnel connection between a edge device and any controller device, the tunnel uses the hello interval and tolerance times configured on the edge device. This choice is made to minimize the traffic sent over the tunnel, to allow for situations where the cost of a link is a function of the amount of traffic traversing the link. The hello interval and tolerance times are chosen separately for each tunnel between a edge device and a controller device. Another step taken to minimize the amount of control plane traffic is to not send or receive OMP control traffic over a cellular interface when other interfaces are available. This behavior is inherent in the software and is not configurable.
   Last Resort Circuit	Select to use the tunnel interface as the circuit of last resort. Note It is assumed that an interface configured as a circuit of last resort is unavailable and is skipped while calculating the number of control connections. As a result, the cellular modem becomes dormant, and no traffic is sent over the circuit. When the configurations are activated on the edge device with cellular interfaces, all the interfaces begin the process of establishing control and BFD connections. When one or more of the primary interfaces establishes a BFD connection, the circuit of last resort shuts itself down. If the primary interfaces lose their connections to remote edges, the circuit of last resort activates itself, triggering a BFD TLOC Down alarm and a Control TLOC Down alarm on the edge device. The last resort interfaces are a backup circuit on edge device and are activated when all other transport links BFD sessions fail. In this mode, the radio interface is turned off, and no control or data connections exist over the cellular interface.
   Allow Services	Click On or Off for each service to enable or disable the service on the cellular interface.
   Encapsulation
   Encapsulation	Enable atleast one of the following encapsulation methods: IPsec: Enter a value to set the preference for directing traffic to the tunnel. A higher value is preferred over a lower value. Range: 0 through 4294967295 Default: 0 IPsec Preference: From the drop-down list, select Global and enter a value to set the preference for directing traffic to the tunnel. A higher value is preferred over a lower value. Range: 0 through 4294967295 Default: 0 IPsec Weight: From the drop-down list, select Global and enter a value to set weight for balancing traffic across multiple TLOCs. A higher value sends more traffic to the tunnel. Range: 1 through 255 Default: 1 GRE: Enter a value to set GRE preference for TLOC. Range: 0 through 4294967295 GRE Preference: From the drop-down list, select Global and enter a value to set the preference for directing traffic to the tunnel.
