About Uplink Interfaces

Uplink interfaces can be viewed as “trunk” ports set up to carry tagged/untagged traffic. When an extended switch is added with appliance uplink and X-Switch uplink options, the port on the appliance configured as the SuperMassive uplink and the port on the extended switch configured as the switch uplink are set up automatically to receive/send tagged traffic for all IDV VLANs. The IDV VLAN of the tagged traffic allows the firmware to derive the PortShield host interface for the traffic.
