The port assignments for the VLANs are as follows:
This configuration is similar to the port-based VLAN example earlier in
this appendix, but untagged ports have replaced several connections.
The changes are noted below:
❑ Uplink to the AT-8224XL switch - In the earlier port-based VLAN
example, each VLAN in the AT-8300 stack had a dedicated
connection to its corresponding VLAN in the AT-8224XL Switch.
These connections have been replaced with one connection. Port
10 on the AT-8324 slave switch has been made a tagged member
of both VLANs, as has port 9 on the AT-8224XL switch. The
connection between the ports now carries traffic for both VLANs.
However, frame traffic is restricted to its respective VLAN member
ports.
❑ Uplink to an IEEE 802.1Q-compliant server - Port 16 on the AT-
8324 slave switch has been connected to an IEEE 802.1Q-
compliant server, meaning the device is capable of handling
tagged frames. By designating it as a tagged port of both the Sales
and Production VLANs, end-nodes from either VLAN can access
the resource without having to pass through a router.
❑ Uplink to an IEEE 802.1Q-compliant router - Port 11 on the AT-
8324 master switch has been connected to a router and has be
made a tagged member of both VLANs. Access to the WAN is now
possible for both VLANs over the one connection.
