Do Low-end and Mid-range Firewalls Support Data Forwarding Cross Layer-2 Switching Cards?
Low-end and mid-range firewalls support data forwarding cross Layer-2 switching cards on the following conditions:
1. The Layer-2 switching cards must be connected by network cables.
2. VLAN parameters and up-link enable must be configured on the directly connected interfaces.
The two Layer-2 switching cards can be regarded as two independent switches. For the two switches to communicate, you need to connect them with network cables and set VLAN parameters.
