How to check from Logs if SRB3 is implemented in network?

Hi Experts,
How to check from Logs if SRB3 is implemented in network?

First check if UE support SRB3 or not under UE capability.
It should be under “General Parameters”.

I can’t see srb3 under MRDC general para.

Then it’s not supported.

Do a search for srb3 in entire UE capability.

I can see this msg between MS and gNodeB:

From the report config it is used for periodic ssb meas.

The supported messages for SRB3 are RRC Reconfiguration, RRC
Reconfiguration Complete and Measurement Report.
