Cisco Works LMS 2.6 DFM 2.0.10 is reporting the above message on a 6509 Server Farm switch that uses a Sup 720 with Modular IOS 12.(18)SXF7.
Now I know that this code is badly bugged and I have a change scheduled for next week to revert back to a safe harbour release of standard IOS (non modular).
However I am very concerned about DFM reporting this message. I have looked at the switch and a "show memory" doesn't report any problem:
System Memory: 524288K total, 294084K used, 230204K free, 1000K kernel reserved
Lowest(b) : 235171840
Howver, looking through the notes for DFM 2.0.10 I read the following :
An ION switch is an IOS running on a new type of processor. The
memory allocation is different. The "show memory" on an ION switch
does not show the real memory usage. However, DFM is using the MIB
to poll the exact info of "show memory" and report with the
"Insufficient Memory" event.
When the available memory space went below the threshold level, now
the "InsufficientFreeMemory" alert is seen in AAD.
So am I to take it that a "show memory" on a switch running modular IOS doesn't provide you with accurate information ?
If this is the case, what are the ramifications of this issue and should I bring the IOS change forward ?
