3. Click on the
VLAN
tab to open a window that displays port-based settings for
VLANs, outgoing tags, and incoming tags:

Figure 4.
Port associations enable you to assign a
VLAN broadcast domain to a single PAN port or
group of associated ports.
4. Under
Port-based VLANs
, make sure the
Port Association
box is checked.
5. You should see four tabs, one for each PAN port. Select the
Port 1
tab and check the
Port 2
box. This configures Ports 1 and 2 to share traffic with each other but not
ports 3 or 4.
6. Next, select the
Port 3
tab and check the
Port 4
box. This configures Ports 3 and 4
to share traffic with each other but not ports 1 or 2.
Note:
It is possible to override these port configurations with a higher-level device, such as a core switch
that supports Layer 3 IP forwarding between VLANs.
Setting Outgoing and Incoming Tag Schemes
Once the Port Associations have been set up, the PAN ports can be assigned to VLANs
using the appropriate VLAN ID (VID) numbers. The PAN-port VIDs can be any number
from 0 to 4095 and must match the core-switching VIDs, which are typically assigned
by the enterprise network management platform.
IMPORTANT:
If any PAN port is configured with a VID that has no corresponding upstream match, the
entire switch may lose network connectivity. To reset the LAN port and recover network communications,
the NJ200 Network Jack must be connected to a hub or flat VLAN. It can then be reconfigured with the
proper VID using 3Com Central Configuration Manager.
