• If the interface is disabled, enable it with the no shutdown command.
• If misconfiguration is apparent, refer to
Trunk member not used for information on how to
configure fabric trunks.
• If you notice significant errors in the error statistics counters, depending on the error, check the
SFP transceiver and cable on the local switch and on the peer switch at the other end of the cable.
1. Enter the show media interface command on each switch and check the Vendor Name field to
check that the optics are Brocade-certified. If the Vendor Name field shows anything other than
BROCADE, replace the optics with Brocade-certified optics.
2. Replace any non-Brocade SFP transceiver.
3. Try replacing the SFP transceiver.
4. Try replacing the cable.
Upgrade fails
If a failure occurs during firmware upgrade, complete the following steps.
1. Revert to the previous firmware version.
2. Contact your switch support provider to evaluate whether retrying the upgrade is appropriate.
VCS Fabric cannot be formed
A VCS Fabric can fail to form for several reasons:
• The required licenses are not active. Refer to Verifying VCS Fabric licenses on page 709.
• The VCS Fabric configuration is incorrect. The following configuration issues will prevent the VCS
Fabric from forming:
‐ VCS Fabric mode has not been enabled.
‐ The VCS ID on the constituent switches is not the same.
‐ Multiple switches have the same RBridge ID.
‐ ISL ports that connect the switches are not up.
Refer to Verifying the VCS Fabric configuration on page 710.
Verifying VCS Fabric licenses
If the VCS Fabric cluster has just one or two switches, no VCS Fabric license is required. For more than
two switches to exist in a VCS Fabric cluster, you must have the VCS Fabric license installed.
1. Enter the show license command to check whether the required VCS Fabric license is installed.
switch# show license
rbridge-id: 66
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
FCoE Base license
Feature name:FCOE_BASE
2. If the VCS Fabric license is not listed in the output of the show license command, enter the license
add licstr command to enable the license.
switch# license add licstr "*B

3. Enter the show license command again to verify that the license has been added.
