Definition of log entry: %IPFFT-W-SFFTREDYELLOW:

Unanswered Question
May 4th, 2010

We have a switch stack with 4 switches (SGE2000 and SGE2000P) and we are seeing the log messages below filling up the logs. Can one of the Linksys engineers please provide a definition of the %IPFFT-W-SFFTREDYELLOW log message?

We have not seen this message on other SGE switch stacks with very similar configurations.

Thank you.

I have this problem too.

Hi Andrew,

I have already opened a case for this, but apart from our initial contact from your support staff, all my follow up emails have been ignored. No case number was given either. Our account manager advised posting it here.

Cheers,

Steve

Hi Steve,

my customer has exactly the same error messages. Do you have news concerning these messages?

Hello,

I do not recall getting an answer for the specific logs ... just a suggestion to call support and get a RMA.  Your case may be different though ...

Have you all tried support?

Hi Markus,

No, unfortunately the cause of this was never determined. It hasn't happened again since.

It's quite surprising that no one at Cisco could give us a definition for their own syslog messages.

Cheers,

Steve

Understood.

Just curious, did you get a RMA or anything?

If you like, you can call back in and ask for an escalation.  HTH,


Andrew

Hi Andrew,

An RMA was offered back when we originally logged the call, but we weren't interested in wasting the time required to replace the hardware if Cisco couldn't tell us that it was actually a hardware fault. (this was a stack, not an individual switch). And so far the problem hasn't occurred again which suggests we made the right choice.

The underlying issue is that no one at Cisco could give us a definition of the above log message. If we knew what it meant, we (and Cisco) would be in a better position to determine whether replacing the hardware would actually fix any problem or whether it is a software fault.

Regards,

Steve

Steve,

I have located some information about the error you saw in the switch.

This message is not an error, it is just an informational message related to directly connected hosts in the ARP table. The switch keeps a list of directly connected hosts that is constantly updating. When the switch reaches more than 200 directly connected hosts in the ARP table, this kind of message starts to appear. At this point the switch will clear part of the ARP table in order to keep at most 180 used addresses.

As previously mentioned, this is not causing any problems on the switch. The "ip caused the problem" part is bad phrasing and only means that the table reached the maximum number of addresses. The switch should function fine.
