[L] Change in libosmo-sigtran[master]: Add Cisco like DSCP configuration support - gerrit-log

2 Oct 2026

pespin has submitted this change. ( https://gerrit.osmocom.org/c/libosmo-sigtran/+/43667?usp=email )
Change subject: Add Cisco like DSCP configuration support
......................................................................
Add Cisco like DSCP configuration support
Add Cisco like VTY configuration support for DSCP. QoS classes can be
defined and configured per SS7 instance and the classes can be assigned
to listener and connections like this:
cs7 instance 0
     qos class 3
      qos-ip-dscp 36
     ...
     asp myasp 2905 2905 m3ua
      qos-class 3
     ...
     asp asp-srv-m3ua 2906 2905 m3ua
      qos-class 3
     ...
     asp asp-clnt-m3ua 2905 2906 m3ua
      qos-class 3
     ...
Ensure that the ongoing listener or connection socket is updated
whenever the QoS class is changed or deleted or its DSCP value is
changed.
Deprecated "ip-dscp" and "init-ip-dscp" configuration is still
supported. When QoS class is assigned, the deprecated configuration is
removed and vice versa.
Update vty tests to the new VTY command layout and test the new VTY
commands.
