Cisco UCS – FSM:FAILED: Ethernet traffic flow monitoring configuration error

During a recent Cisco UCS upgrade I noticed an error for ethlanflowmon which was a critical alert. I hadn’t seen the problem before and it occurred right after I had upgraded UCS Manager firmware as per the steps listed in a previous post I wrote about UCS Firmware Upgrade. Before proceeding to upgrade the Fabric Interconnects I wanted to clear all alerts where possible. The alert for “FSM:FAILED: Ethernet traffic flow monitoring configuration error on” both switches was a cause for concern.

ethlanflowmon1On further investigation I found that this is a known bug when upgrading to versions 2.2(2) and above. I was upgrading from version 2.2(1d) to 2.2(3d). Despite being a critical alert the issue does not impact any services. The new UCSM software is looking for new features on the FI that do not exist yet as it has not been upgraded. As soon as you upgrade the FIs this critical alert will go. More information about the bug can be found Cisco’s support page for the bug CSCul11595
