CEE network problems (CNA only)

This section provides information to resolve problems of CNA operation on the converged

enhanced Ethernet (CEE) network.

CEE is not enabled

The CEE state does not show “CEE Linkup” when you run the bcu port --query command.

1. Possible Cause: The link between the CNA port and switch is down.

Action: Run the cee --query command for the port to gain a better understanding of LLDP

attributes, CEE maps, and priority tables configured for the port. Also check the error reason

code for the CEE link failure. The error reason code will tell you why the CEE is not enabled or

active. If the error reason is “Physical Link down,” refer to “Port link is not active” on page 9

and “Verifying Fibre Channel and CEE links” on page 32

2. Possible Cause: Adapter did not receive CEE configuration or received invalid CEE

configuration from the FCoE switch.

Action: Run the BCU cee --query command for the port to gain a better understanding of LLDP

attributes and CEE configuration (such as CEE maps and priority tables) configured for the

port. Also check for the error reason code for the CEE link failure. The reason code will tell you

why the CEE is not enabled or active. Change or fix the CEE configuration at the switch

appropriately based on the displayed error reason code.

Action: Check FCoE switch configuration using the appropriate Fabric OS command on the

attached switch. Refer to the Fabric OS Command Reference Manual for information. Change

configuration as necessary using appropriate Fabric OS command on the attached switch.

Refer to the Fabric OS Command Reference Manual for information.

3. Possible Cause: The front-end Ethernet port on the FCoE switch is not configured as

“switchport” or is not set to converged mode.

Action: Use the appropriate Fabric OS command on the attached switch to display information

about the VLAN interface. Refer to the Fabric OS Command Reference Manual for information.

Action: Configure the FCoE port as a “switchport” using the appropriate Fabric OS command on

the attached switch. Refer to the Fabric OS Command Reference Manual for information.

Action: Configure the FCoE port to converged mode using the appropriate Fabric OS command

on the attached switch.

Verifying Fibre Channel and CEE links

Check for link problems by observing LED operation for adapter ports. LED operation other than

expected or LEDs may indicate link problems. For example, all LEDs flashing amber for a port

indicates that an invalid non-Brocade SFP may be installed. For details on adapter LED operation,

refer to the “LED Operation” section for your adapter (CNA or HBA) in the Brocade Adapters

Installation and Reference Manual. If LEDs do not illuminate to indicate an active link, use

appropriate Fabric OS and adapter diagnostic commands and HCM options in Table 3 on page 33.

For additional diagnostics commands, refer to Chapter 3, “Tools for Collecting Data” for HCM and

BCU commands and the Fabric OS Administrators Guide for Fabric OS commands.
