Debugging 

If the FCoE link is not up, QLogic SANsurfer will display the corresponding status as Link Down, along with warning 

events. Additional diagnostics may be needed to identify root cause. 

 

 

 

 

 

The adapter and switch exchange various states before declaring the FCoE link on each side. By tracing the state 

transition between the adapter and the switch, it is possible to identify the state that prevented the link from coming 

up. 

Since all the states are managed at the Cisco Nexus Family switch level, run the commands that follow at the switch 

level. A current state of FCOE_MGR_ETH_ST_UP means that DCBX was exchanged successfully. 

If DCBX exchange was not successful, the problem may be a firewall mismatch between the adapter and the switch. 

In this case, the current state is set to FCOE_MGR_ETH_ST_INIT, and no progress can be made with respect to 

state transition. For this kind of scenario, please contact Cisco or QLogic support personnel.  

Run the following command on the switch for a given port interface to obtain the current state of the port along with 

the history associated with state transition.
