CPU and MEM Utilization of Catalyst 2960s

Hello,

i have some questions regarding the CPU and Memory Utilization of Cisco Catalyst 2960s:

is it normal, that they have a cpu utilization of ~20-30% and a I/O Memory Utilization of about ~85%?

has anybody an official documentation regarding this phenomenom?

here are a example outputs:

our switches are running with 15.0(2)SE4 - this version seems to be stable.

(but with 12.2(58)SE2 and 12.2(55)SE7 it´s near the same - only the disadvantage, that there are many cpu bugs (58) or AAA issues...)

thany you!

kind regards,

michael
