# Enroll SDRs

A software-defined radio at ExPECA is a networked device with 2 data ports, one SFP and one rj45, all assigned static IPs. These ports are connected to the tenants switch and configured with an static IP in the `10.30.1.0/24` subnet for the RJ45 ports, and `10.30.10.0/24` for the SFP ports. Our approach is to map each port to a network segment (a VLAN on the tenants switch). We register them as network segments in blazar in the following format:

Register the RJ45 port:

```
openstack reservation network create \
--network-type "vlan" \
--physical-network "physnet1" \
--segment "102" \
--extra segment_subnet="10.30.1.0/24" \
--extra segment_gateway="10.30.1.100" \
--extra vlan_id="102" \
--extra baremetal_ports='[{"name":"sdr_02_rj45","ip-address":"10.30.1.4","binding-profile":{"local_link_information":[{"switch_id":"a0:f8:49:f7:89:d1","port_id":"te1/0/29","switch_info":"tenant-switch"}]}}]'
```

Register the SFP port:

```
openstack reservation network create \
--network-type "vlan" \
--physical-network "physnet1" \
--segment "103" \
--extra segment_subnet="10.30.10.0/24" \
--extra segment_gateway="10.30.10.100" \
--extra vlan_id="103" \
--extra baremetal_ports='[{"name":"sdr_02_sfp","ip-address":"10.30.10.4","binding-profile":{"local_link_information":[{"switch_id":"a0:f8:49:f7:89:d1","port_id":"te2/0/14","switch_info":"tenant-switch"}]}}]'
```

NOTE: It is very important that in `local_link_information` the `switch_info` value be set to the tenant switch name in "defaults.yaml".

Check the ports:

```console
(venv) expeca@controller-01:/opt/chi-in-a-box$ openstack reservation network list
+------------------+--------------------------------------+--------------+------------+

| physnet1         | 6f533bfd-5205-4e3f-914b-b1172aa4e50b | vlan         |        102 |
