VLAN Operation Issues
The correct VLAN configuration can be verified by “pinging” wired hosts from both sides of the device and the network
switch. Traffic can be “sniffed” on the wired (Ethernet) network. Packets generated by hosts and viewed on one of the
backbones should contain IEEE 802.1Q compliant VLAN headers when in Transparent mode. The VLAN ID in the
headers should correspond to one of the VLAN Management IDs configured for the unit in Trunk mode.
The correct VLAN assignment can be verified by pinging:
• The unit to ensure connectivity
• The switch to ensure VLAN properties
• Hosts past the switch to confirm the switch is functional
Ultimately, traffic can be “sniffed” on the Ethernet interface using third-party packages. Most problems can be avoided by
ensuring that 802.1Q compliant VLAN tags containing the proper VLAN ID have been inserted in the bridged frames. The
VLAN ID in the header should correspond to the assigned VLAN.
What if network traffic is being directed to a nonexistent host?
• All sessions are disconnected, traffic is lost, and a manual override is necessary.
• Workaround: You can configure the switch to mimic the nonexistent host.
