Switch C2960S - High I/O memory utilizatioN

[Hugo Thomaz]

Dear,

I'm look my switch of access and identifed that I/O memory is bigger that 80% of utilization.

Information of switch:

Switch   Ports     Model                               SW Version          SW Image

I will like known if this is high I/O memory utilization is normal?  Why the I/O memory is high?

Thank you.

Hi there,

Have a look at the below link to see if you have a similar issue, and perhaps move up to a Newer 12.2 IOS Version or

the Latest IOS Suggested by Cisco on the 15 Version release. I hope this info gets you out of trouble.
