Section II: Local and Telnet Mangement

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-8024 Switch - In the earlier port-based VLAN
example, the Sales and Production VLANs in the AT-8300 Series
stack had dedicated connections to their corresponding VLAN in
the AT-8024 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-
8024 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 or Layer 3
switch.
