Ethernet network interface problems (CNA only)

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: Pass-through 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 vlan --list.”

Possible Cause: Port VLAN is configured in Device Manager.

Action: Set port VLANID to 0 in Device Manager.

Enabling and disabling port VLAN in Device Manager

Access the port VLAN configuration in Device Manager using the following steps

1. Open Device Manager.

An instance of the adapter model should display for each installed adapter port.

3. Right-click an adapter instance and select Properties.

4. Select the Advanced tab.

5. Select VlanID.
