Re: 3750g and 3750x High Memory Utilization

Rich Rangel · ‎06-12-2013

We had a stack of 4 qty 3750g running IP base on ver 12.2.32, then installed a 3750x to the stack and upgraded the whole stack to 15.0.2 SE3. In doing so, we noticed that the memory utilization jumped from 60-70% to 83-84%.

We had the same issue occur when upgrading to 15.0.2 SE3 on another stack that was 6 qty 3750g running ip-services, but this one jumped to 90%. On the 6 qty stack, we downgraded to 12.2.55 and the memory util went back down to 60-70%.

On the mixed stack, we replaced the 3750x with another 3750g and downgraded the whole stack to 12.2.55, however, the memory utilization did not drop down. As far as I can tell, no config changes have changed from the original IOS. Any thoughts or directions that you can think of to try would be greatly appreciated. Thank you.

I agree with Inayath. Stay away from 15.0(2)SE3.

Use 12.2(55)SE7.

Post the output to the command "sh version".

Good way to go. All the devices in stack are on safe software.

So are you facing any issues currently?

I am also experiencing a high memory load. I'm using software: Version 15.0(2)SE2, RELEASE SOFTWARE (fc1) on a WS-C3750G-24TS-1U.

I looked at current IOS versions for this device and it looks like: c3750-ipservicesk9-mz.150-2.SE5.bin is the latest. Does anyone know if this would fix the memory usage issue?
