  • 1.  128T LTE , high backup utilisation

    Posted 12-22-2022 10:36

    Does anyone have tips for identifying what is causing our LTE backup to have unusual utilisation. We have configured as backup only with outgoing sessions. Even when Primary link is solid we are seeing high data volume on the LTE backup. Think this could be our Managment polling via the LTE, but the amount of traffic seems too high for monitoring only.

    Any Tips ?

    Here is the documentation for configuring optimal LTE peering. LTE Peering | SSN Docs (

    I have a router that I'm testing LTE on. Another thing I did to limit the bandwidth used for peering was to put that interface in a neighborhood that only peers with a few hub routers, rather than meshing and peering with ALL my other routers.
