Hi All,
Please suggest which MO can be checked to see S1-User plane definition in Ericsson.
I could only see S1-C(Termpointtomme) in all the nodes I have verified.
On the eNodeB there is no S1-U peer MO. TermPointToMme exists because S1-C has a static SCTP association per MME, but S1-U has no equivalent term point, because S1-U bearers are set up per UE over GTP-U at call setup and the SGW endpoint comes in the S1AP signalling, not from a configured MO.
What defines S1-U on the node is the local GTP-U termination address in the transport branch under EnodeBFunction, not a peer MO. Get the node type and release and check the exact MO and attribute holding that S1-U GTP-U endpoint.
Okay noted. So should I have to give get enodefunction=
Not EnodeBFunction directly, that holds the S1 function but not the user-plane IP. The S1-U GTP-U endpoint lives in the transport branch, and the exact MO depends on release. Two ways to find it fast on the node.
Reverse-map from the address. Run
st Sctp lt all get . gtpu
The get . gtpu (dot-match on all MOs containing gtpu) will return the Gtpu MO and the reference to the IP address it uses for S1-U. That is the quickest, it lists the user-plane endpoint wherever it sits in your release.
Then follow the reference. The Gtpu MO points to an AddressIPv4 (or the endpoint reference MO in newer releases) under the transport configuration, and that address is your S1-U termination.
Run get . gtpu first and paste the output. Tell me the node type and release with it, and I will name the exact MO and attribute so you can pull it in one command next time.
