• Configuring a dedicated uplink plus a common uplink for VLANs
Prerequisites for VLAN support
• Support for VLANs is available only on dedicated uplinks. Support for VLANs is not available on common
uplinks. For example, VLANs cannot be configured under the firewall interface provisioned as the
common uplink for the X-Series switch.
• 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.
Configuring a dedicated uplink for VLANs

Dedicated Uplink for VLAN Topology
In a dedicated uplink configuration, a given link between the firewall and the X-Series switch designated as the
dedicated uplink is set up to carry traffic for all VLANs configured under the firewall interface plus PortShield
traffic corresponding to the firewall interface.
Figure 7 shows a TZ500 with an X1026P switch:
Figure 7. VLAN with dedicated uplink topology
• The link between X3 and port 1 on the extended switch is used by the firewall to manage the switch.
• Interface X3 is configured to be in the same subnet as the IP of the switch.
NOTE: In this example, a common uplink is not required, hence, the extended switch is provisioned
with the Firewall Uplink and Switch Uplink options set to None and Switch Management set to 1.
• There are three VLAN interfaces with VLAN tags 100, 150, and 200 configured under X5.
• The link between X5 on the firewall and port 3 on the extended switch is a dedicated link set up to carry
traffic tagged with VLANs 100, 150, and 200 and untagged traffic for X5.
