#### Run OAI with SDAP & Custom DRBs
To run OAI gNB with SDAP, simply include `--gNBs.[0].enable_sdap 1` to the binary's arguments.
SDAP is enabled by default. To disable SDAP, include `--gNBs.[0].enable_sdap 0` to the binary's arguments.
The DRB creation is dependent on the 5QI.
If the 5QI corresponds to a GBR Flow it assigns a dedicated data radio bearer.
