%FRNTEND_CTRLR-1-MGR_TXQ_FULL: The front end controller Tx queue reached watermark level

Experts,

Can somebody elaborate on what this error means? According to Cisco docs, " There are too many messages in the queue between the front-end controller and the  switch software." I have not tried rebooting. Wanted to get clarification before doing so.

What kind of messages?

Could this affect PoE operation?

I'm receiving this error on a C2960S Software (C2960S-UNIVERSALK9-M), Version 12.2(55)SE3, RELEASE SOFTWARE (fc1)

Thanks!

%FRNTEND_CTRLR-1-MGR_TXQ_FULL: The front end controller Tx queue

Hi Thomas,

Usually when ever you will see the RedEarth Rx Mana process consuming high CPU we will see the following error message:

"%FRNTEND_CTRLR-1-MGR_TXQ_FULL: The front end controller TX queue reached watermark level"

This process is used for Punted Packet Handling. It is normally used for Microprocessor communication process i.e. it does periodic polling on the I2C interface connected to Microprocessor Controller Unit. Microprocessor Controller Unit (MCU) and IOS does sync up on various applications data e.g. PoE, Stack Power etc.

So in this situation when the device is reloaded problem gets fixed.

But if you see this message even without the above mentioned process not consuming high CPU or even after reload the error logs keep appearing, then it means the HW on the switch has gone faulty. And needs replacement.

Hi Thomas,

"%FRNTEND_CTRLR-1-MGR_TXQ_FULL: The front end controller Tx queue reached watermark level"

This message means that there are too many messages in the queue  between the front-end controller and the switch software.

Yes POE operation might get affected because of this situation.


Try reloading the switch and if this does not resolve the issue, then it should because of a bad hardware. Please have the switch replaced.

This conclusion has been arived upon after researching the internal database.

%FRNTEND_CTRLR-1-MGR_TXQ_FULL: The front end controller Tx queue

Hi Thomas,

At the time you collected the "show proc cpu sorted" output where the "%FRNTEND_CTRLR-1-MGR_TXQ_FULL" error los still being seen ?

Thanks & Regards,

%FRNTEND_CTRLR-1-MGR_TXQ_FULL: The front end controller Tx queue

Hi Thomas,

Usually when ever you will see the RedEarth Rx Mana process consuming high CPU we will see the following error message:

"%FRNTEND_CTRLR-1-MGR_TXQ_FULL: The front end controller TX queue reached watermark level"

This process is used for Punted Packet Handling. It is normally used for Microprocessor communication process i.e. it does periodic polling on the I2C interface connected to Microprocessor Controller Unit. Microprocessor Controller Unit (MCU) and IOS does sync up on various applications data e.g. PoE, Stack Power etc.

So in this situation when the device is reloaded problem gets fixed.

But if you see this message even without the above mentioned process not consuming high CPU or even after reload the error logs keep appearing, then it means the HW on the switch has gone faulty. And needs replacement.

Re: %FRNTEND_CTRLR-1-MGR_TXQ_FULL: The front end controller Tx queue

Hello!

 

We're currently running 12.2(55r)SE on a WS-C2960S-48LPS-L and the switch started writing the following messages:

 

Aug 9 07:30:19 xxxxxxxx 56: Aug 9 05:30:32.069: %FRNTEND_CTRLR-1-MGR_TXQ_FULL: The front end controller Tx queue reached watermark level
Aug 9 07:35:20 xxxxxxxx 57: Aug 9 05:35:32.910: %FRNTEND_CTRLR-1-MGR_TXQ_FULL: The front end controller Tx queue reached watermark level
Aug 9 07:40:21 xxxxxxxx 58: Aug 9 05:40:33.761: %FRNTEND_CTRLR-1-MGR_TXQ_FULL: The front end controller Tx queue reached watermark level
Aug 9 07:45:21 xxxxxxxx 59: Aug 9 05:45:33.788: %FRNTEND_CTRLR-1-MGR_TXQ_FULL: The front end controller Tx queue reached watermark level
Aug 9 07:50:21 xxxxxxxx 60: Aug 9 05:50:34.545: %FRNTEND_CTRLR-1-MGR_TXQ_FULL: The front end controller Tx queue reached watermark level
Aug 9 07:55:22 xxxxxxxx 61: Aug 9 05:55:35.196: %FRNTEND_CTRLR-1-MGR_TXQ_FULL: The front end controller Tx queue reached watermark level
Aug 9 08:00:22 xxxxxxxx 62: Aug 9 06:00:35.286: %FRNTEND_CTRLR-1-MGR_TXQ_FULL: The front end controller Tx queue reached watermark level

...

until Aug 13 11:57:52 - then it was rebooted for changing power cord.

 

about 4hrs before (in between nothing!) also this messages have been received:

 

Aug 9 03:11:48 xxxxxxxx 54: Aug 9 01:12:01.573: %HARDWARE-3-MCU_I2C_READ_ERROR: I2C read failed in MCU and attached devices (e.g. Temperature Sensor) can't be read.
Aug 9 03:11:48 xxxxxxxx 55: Aug 9 01:12:02.574: %HARDWARE-3-MCU_I2C_BAD_DEV: I2C bad device address: 4 (alchemy:0)

 

As a consequent the switch turned of all power feeds to POE devices (12 IP cams class 3 with 15,4W per device)!

 

Some additional informations: this actual switch already has been replaced by RMA about 4 weeks ago because the old one suddenly began to shutdown itself completly. The new one also shows the same symptoms after some days. Powercord has been replaced and is pluged together with an other switch which doesn't show this problem.

The POE devices now have been attached to power injectors to get sure that this is not the trigger.

 

So is this a hardware problem caused by one or more PE devices or the switch itself or is it a software problem indeed?

 

Best regards,

Herbert
