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 NJ205 IntelliJack Switch must be connected to a hub or flat VLAN. It can then be reconfigured with the
proper VID using 3Com Central Configuration Manager.
