Why TMOS Version Matters

There are different commands depending on whether or not the Management Interface has been selected for Signals.
In different BIG-IP versions, the Management Interface has a different name.
- Starting in TMOS v13.0.0 the interface is called: 'mgmt'.
- For previous versions, it is called 'eth0'.

Step 2: Check BIG-IP Access

TMOS v 13.0.0 and newer with Management Interface

From the on-prem BIG-IP CLI, to ensure connectivity to the F5 Silverline Cloud Platform, execute the following command:
- ```
curl -s -o /dev/null --interface mgmt -w "\n%{http_code}\n\n" https://api.f5silverline.com
```
- Example output
Ensure a response of "302" is received.
For a full curl response, the following command can be utilized:
- ```
curl -I https://api.f5silverline.com
```

TMOS Pre v 13.0.0 With Management Interface

From the on-prem BIG-IP CLI, to ensure connectivity to the F5 Silverline Cloud Platform, execute the following command:
- ```
curl -s -o /dev/null --interface eth0 -w "\n%{http_code}\n\n" https://api.f5silverline.com
```
- Example output
Ensure a response of "302" is received.
For a full curl response, the following command can be utilized:
- ```
curl -I https://api.f5silverline.com
```

Without Management Interface

From the on-prem BIG-IP CLI, to ensure connectivity to the F5 Silverline Cloud Platform, execute the following command:
