Port 16 on the AT-8224XL Switch and port 9 on the AT-8324 Switch
function as the uplink ports that interconnect the two switches. To allow
the VLANs to span across the switches, these uplink ports are output
enabled for every configured VLAN on the switch. Therefore, when a
broadcast packet is received on any port (representing a packet on any
VLAN), it is transmitted through the uplink port.

For example, a workstation connected to port 1 on the AT-8224XL
Switch can talk to the legacy server connected to the AT-8324 Switch,
because the workstation and server belong to the same Accounting
VLAN. The workstation’s VLAN information is preserved across the
uplink. Similarly, a workstation connected to port 14 on the AT-8324
Switch, which is a member of the Manufacturing VLAN, can talk to the
legacy server and the IEEE 802.1Q compliant server that are connected
to the AT-8224XL Switch.

On the other hand, a workstation connected to port 22 on the
AT-8224XL Switch cannot talk to the legacy server on the AT-8324
Switch because they belong to different VLANs.
