How to configure management port with static IP for SSR devices to use for WAN assurance / MIST.

This article speaks about a "One time provisioning" method.

This method involves connecting to the local console of the device, and pasting in some one-time provisioning information including the static address.

1. Claim the device to your Mist org inventory (if not done already), and power it on.
2. Locate the device in your Mist WAN Edge inventory, and assign it to your site (remember to have “Manage configuration with Mist” selected).
3. Connect a laptop or PC to the local serial console port of the SSR device on site.
4. Enter the default SSR login information.
5. Copy the following 4 lines of configuration, changing the {{wan0_static_ip}}, {{wan0_prefix}}, and {{wan0_gateway}} in the text to the static address details for the site.

configure authority router router node node device-interface ge-0-0 network-interface ge-0-0-intf dhcp disabled
configure authority router router node node device-interface ge-0-0 network-interface ge-0-0-intf address {{wan0_static_ip}} prefix-length {{wan0_prefix}}
configure authority router router node node device-interface ge-0-0 network-interface ge-0-0-intf address {{wan0_static_ip}} gateway {{wan0_gateway}}

6. Connect the device to the appropriate static WAN links.
7. Locally on the device, you can verify the local link state and connectivity using commands such as show arp, show network-interface, and ping.

8. In Mist, monitor WAN Edge events for the site to verify the device connects to Mist, and receives the configuration. 

**Note: a device upgrade may be required in order for the device to fully apply and run the Mist config.
