Does the 8FE-1GE support Layer 2 and Layer 3 switchover

0

The 8FE-1GE is a Layer 2 Ethernet interface which does not support switchover to a Layer 3 interface. A Layer 3 interface supports routing and forwarding on the local card, which is irrelevant to the interface attributes. A VLANIF route will be delivered to a card so that Layer 3 forwarding requests may not be reported to the SRU and Layer 3 forwarding can be implemented on the local card.

Configuring Layer 2/Layer 3 switchover on the firewall
Perform as follows to configure Layer 2/Layer 3 interface switching on the USG2000&5000&6000: system-view [USG] interface GigabitEthernet 1/0/1 [USG-GigabitEthernet1/0/1] undo portswitch //Switch the interface from Layer 2 mode to Layer 3 mode. [USG-GigabitEthernet1/0/1] portswitch //Switch the interface from Layer 3 to Layer 2. Note: 1. If the device interface attribute specifies that the interface is a Layer 2 interface, the interface cannot be switched to Layer 3 mode. This command applies only to interfaces that support Layer 2/Layer 3 switching. 2. When you use this command to perform Layer 2/Layer 3 mode switching, the interface can contain only the attribute information (such as shutdown and description configurations) so that the mode switching can take effect. If the interface already has service configurations (such as port link-type trunk), clear all these configurations of the interface and then run this command.

Does an AR router support an interface being switched over between Layer 2 and Layer 3
The following AR routers support an interface being switched over between Layer 2 and Layer 3. By default, Ethernet interfaces are Layer 2 interfaces. Run the undo portswitch command to switch the interfaces from Layer 2 mode to Layer 3 mode, and run the portswitch command to switch the interfaces back to Layer 2 mode.

Whether the firewall supports Layer 2 or Layer 3 forwarding
The USG2000&5000&6000 support implementing the Layer 2 forwarding function in transparent mode. When the firewall implements route-based forwarding, the Layer 3 forwarding function is used.
