VLAN creation and operation problems
VLAN creation fails with BCU command or HCM or pass-through VLAN stops working after creating
with Device Manager. These problems result when VLANs are created using HCM or BCU
commands and also using Device Manager. Follow these guidelines to avoid problems:
• If you need to create a single VLAN and VLANs have not been created using BCU commands or
HCM, you can use Device Manager.
• If you want to configure multiple VLANs, disable the port VLAN created in Device Manager (set
to 0 value), then configure VLANs using HCM or BCU. Refer to the Brocade Adapters
Administrator’s Guide for instructions.
1. Symptom: When using BCU commands or HCM, to create VLANs, the initial VLAN fails with an
error message.
Possible Cause: Port VLAN was created through Device Manager.
Action: Set port VLANID to 0 in Device Manager and create VLANs using BCU commands or
HCM.
2. Symptom: Passthru VLAN stops working.
Possible Cause: Port VLAN was configured through Device Manager.
Action: Set port VLANID to 0 in Device Manager.
3. Symptom: Right-clicking on a VLAN device in Device Manager, then selecting Update does not
work.
Possible Cause: The upgrade option for Brocade 10 Gig Ethernet service is not available.
Action: Uninstall and install the service.
4. Symptom: No VLAN operation works except “bcu ethport --vlanlist.”
Possible Cause: Port VLAN is configured in Device Manager.
Action: Set port VLANID to 0 in Device Manager.
