unrecognised option '--slicer.enable=1' in srsRAN nexRAN Running Procedure

[mdalgitsis]

Hello all,

I am trying to deploy the NexRAN xAPP and I am following the guidelines of https://github.com/openaicellular/oaic/blob/master/docs/source/nextranslicing.rst

In the srsRAN nexRAN Running Procedure part when I run the command:

sudo srsenb \
     --enb.n_prb=15 --enb.name=enb1 --enb.enb_id=0x19B --rf.device_name=zmq \
     --rf.device_args="fail_on_disconnect=true,id=enb,base_srate=23.04e6,tx_port=tcp://*:2000,rx_port=tcp://localhost:2001" \
     --ric.agent.remote_ipv4_addr=${E2TERM_SCTP} --log.all_level=warn --ric.agent.log_level=debug --log.filename=stdout \
     --slicer.enable=1 --slicer.workshare=0

I receive an **unrecognised option '--slicer.enable=1'** message.

Step to reproduce the error:

1. I deployed the k8s cluster with RT-RIC and KPIMON xAPP
2. Onboarded and deployed the nexRAN xAPP into RIC
3. Install srsRAN with E2 Agent Installation Guide (https://openaicellular.github.io/oaic/srsRAN_installation.html)
4. RUN the SRSRAN EPC (sudo srsepc)
5. RUN the SRSRAN gNB with E2 agent ( sudo srsenb
   --enb.n_prb=15 --enb.name=enb1 --enb.enb_id=0x19B --rf.device_name=zmq
   --rf.device_args="fail_on_disconnect=true,id=enb,base_srate=23.04e6,tx_port=tcp://*:2000,rx_port=tcp://localhost:2001"
   --ric.agent.remote_ipv4_addr=${E2TERM_SCTP} --log.all_level=warn --ric.agent.log_level=debug --log.filename=stdout
   --slicer.enable=1 --slicer.workshare=0 )

I guess step 3 is missing the RAN scheduler activation/integration.

Where can I find the code and guidelines to install SRSRAN with E2 Agent and RAN scheduler?

Hello again,

I found here https://github.com/openaicellular/srsRAN-e2/blob/eee2bbf6078b0e4987ea086be1a45e4646f1e3e1/CMakeLists.txt#L111
that the options:
Enable RIC E2 Agent NexRAN model and
Enable NexRAN Slicer
are OFF by default. I will change them to ON and install again the SRSRAN.

Anything else that I may be missing?

After I enabled ON the above-mentioned options (RIC E2 Agent NexRAN model and NexRAN slicer)
and install again the SNSRAN I receive the following errors:
