Communication flow between Firewall and Switch before it gets authenticated

If switch Auto-Discovery is not working when a third party switch is in the middle between SW firewall and SW switch. where LLDP packets are not forwarded, the switch can be added manually.

Configure Interface in LAN zone which is connected from firewall to switch. Navigate to Network>interfaces select the interface(X2) and click on Edit.

In the same interface edit and go to Advanced tab and enable the toggle button Enable Auto-Discovery of SonicWall Switches.

Max of eight switches can be added to the firewall.

Now, check and confirm if the DHCP Server lease scopes setting is enabled for that interface.

Once the switch gets an IP from the interface (X2) check and confirm from the Current DHCP Leases tab.

Navigate to External Controllers> Overview>Physical View and check for switch getting authorized.

Click on authorize button

After completing authorization the switch gets added successfully.

Now, you can edit the Switch configuration.

you can view the X2 interface comment section.

View the Switch CLI information

If the switch add is stuck in authorize state and after rebooting the firewall if the switch is not yet added , and also switch add fails after this case, then please follow the below steps

1. Check from switch CLI whether you are able to reach the firewall interface (Ping).

2. If the switch and firewall communication is working still the switch state is authorized state or stuck then Reboot the firewall.

3. If the issue still remains same then remove and add the switch once again after factory resetting the switch.

4. Under Firewall > Configure terminal > clear switch-database

   This will clear all the switch data that is present in the firewall. Please do not use this case when multiple switches are added and issue is seen while adding a new switch, this command will clear all the switch data and needs to add all the switch from the beginning.

5. Reset the switch to Factory default.

6. Once the switch gets the IP from the DHCP range, it appears to authorize the switch.
