Prerequisites for PortShielding X-Series Switches

If the topology has two or more switches, the switches can be cascaded or daisy chained, that is, one switch can be connected to another one that is connected to the appliance.

X-Series switches (excluding X1052/X1052P models) are delivered from the factory in unmanaged mode to avoid unauthorized access to the switch. You need to put the switch into Managed mode by pressing Mode, near the power plug, for at least seven seconds.

X1052/X1052P models delivered from the factory are by default in Managed mode.

During the initial set up of the switch, to ensure the X-Series switch’s IP does not change dynamically when the DHCP server is enabled on the appliance interfaces, choose Static IP instead of Dynamic IP.

For more information on these features, refer to the SonicWall SonicOS X-Series Solution Deployment Guide located on the Support portal at https://www.sonicwall.com/support/technical-documentation/ and select TZ Series in the Select A Product field.

• Apart from the initial IP address, username/password configuration, which can be found on the switch, no other configuration is recommended to be performed on the X-Series switch directly through the switch’s GUI/console. To do so results in the appliance being out-of-sync with the configuration state of the X-Series switch.
• To manage the X-Series switch from the appliance, one of the interfaces of the appliance must be in the same subnet as the X-Series switch. For example, to manage an X-Series switch with a default IP 192.168.2.1, an interface of the appliance needs to be configured in the 192.168.2.0/24 subnet and connected to the X-Series switch.
• Ensure the appliance can reach the X-Series switch by pinging the X-Series switch from the appliance before provisioning/managing the switch from the appliance.
• VLAN support:
  • Support for VLANs is available on shared and common uplinks. For example, VLANs can be configured under the appliance interface, which is provisioned as the shared uplink for the X-Series switch.
  • For details on VLAN support, refer to the SonicWall SonicOS X-Series/ Solution Deployment Guide located on the Support portal at https://www.sonicwall.com/support/technical-documentation/ and select TZ Series in the Select A Product field. Overlapping VLANs cannot exist under appliance interfaces configured as dedicated uplinks. For example, if X3 and X5 are configured for dedicated uplinks, VLAN 100 cannot be present under both X3 and X5. Such a configuration is rejected.
