WS-C2960S-48FPD-L with high memory usage.

I have in my network has a WS-C2960S-48FPD-L that is using more than 90% of memory. The IOS version installed is 150-2.SE2 (c2960s-universalk9-mz.150-2.SE2.bin), could not find out if this is a BUG. The processing is around 23%. Below are the "show processes cpu sorted 5min" and "show processes memory sorted allocated". Thanks for help.

WS-C2960S-48FPD-L with high memory usage.

The IOS version installed is 150-2.SE2 (c2960s-universalk9-mz.150-2.SE2.bin), could not find out if this is a BUG

Avoid using 15.0(2)SE2 at all cost.  There are so many CPU and memory bugs it's well known joke.  Hey, you should try 15.0(2)SE3, if you can still find this IOS, and then you'll be laughing all the way to the loonie-bin.

Use either 12.2(55)SE8 or 15.0(2)SE4 instead.

WS-C2960S-48FPD-L with high memory usage.

Hi,

To troubleshoot memory please follow the below steps:

First, please check if the memory usage is genuine or not, this can be checked by checking the memory status of any other similar switch in the network having similar devices attached. This check is important because even a 95% of memory usage could be normal depending upon the requirements of your network.

If the memory usage is really abnormal and the switch is crashing then note the time between the two crashes.

If the two crashes are in  a GAP of 7 days then take the outpust of "show process memory sorted" 5 times at a gap of 24-36 hours.

It will give you an idea about the process which is constantly holding more and more memory without releasing it.

Once you know the process, you can track the relevant bug.

Moreover, on the 2960 switch the 15.X train has a lot of memory bugs, I would recommend you to downgrade it to 12.2(55) train as it is one of the most stable IOS images on this platform.

Thanks.

WS-C2960S-48FPD-L with high memory usage.

The IOS version installed is 150-2.SE2 (c2960s-universalk9-mz.150-2.SE2.bin), could not find out if this is a BUG

Avoid using 15.0(2)SE2 at all cost.  There are so many CPU and memory bugs it's well known joke.  Hey, you should try 15.0(2)SE3, if you can still find this IOS, and then you'll be laughing all the way to the loonie-bin.

Use either 12.2(55)SE8 or 15.0(2)SE4 instead.

Hi,

To troubleshoot memory please follow the below steps:

First, please check if the memory usage is genuine or not, this can be checked by checking the memory status of any other similar switch in the network having similar devices attached. This check is important because even a 95% of memory usage could be normal depending upon the requirements of your network.

If the memory usage is really abnormal and the switch is crashing then note the time between the two crashes.

If the two crashes are in  a GAP of 7 days then take the outpust of "show process memory sorted" 5 times at a gap of 24-36 hours.

It will give you an idea about the process which is constantly holding more and more memory without releasing it.

Once you know the process, you can track the relevant bug.

Moreover, on the 2960 switch the 15.X train has a lot of memory bugs, I would recommend you to downgrade it to 12.2(55) train as it is one of the most stable IOS images on this platform.

Thanks.
