By default, the BMC and BlueField interfaces are configured as follows (static IPs and MACs):

	BMC	BlueField
Interface Name	"tmfifo_net0"	"tmfifo_net0"
MAC Address	00:1A:CA:FF:FF:02	00:1A:CA:FF:FF:01
IP Address	192.168.100.1	192.168.100.2

Enable RShim on DPU BMC

Disable RShim on the host. Run the following on the host:
Copy

Copied!
```
            
            systemctl stop rshim
systemctl disable rshim
        
```
Info

If the RShim driver is not installed on the host, this step can be skipped.

Enable RShim on the BMC using the Redfish interface:

Copy
Copied!

            
            curl -k -u root:'<password>' -H "Content-Type: application/json" -X PATCH -d '{
      "BmcRShim": {
        "BmcRShimEnabled": true
      }
}' https://<bmc_ip>/redfish/v1/Managers/Bluefield_BMC/Oem/Nvidia

Check the current BmcRShimEnabled value and wait until it changes to true:
Copy

Copied!
```
            
            curl -k -u root:'<password>' -H "Content-Type: application/json" -X GET https://<bmc_ip>/redfish/v1/Managers/Bluefield_BMC/Oem/Nvidia
        
```
Info

This may take up to 8 seconds. If the BmcRShimEnabled value does not change, disable BMC RShim by setting the value to false then repeating steps 1-3.
