How to clear interface counters on an SSR router?

Example:

user@SSR-01# show device-interface name Wan1 | grep error

Piping output...

in-errors: 56

out-errors: 545

To clear the interface counters on an SSR router, it requires a 128T service restart. This can be done from the UI on the router page or from the router's Linux shell (systemctl restart 128T).
