3750 High cpu

Not sure what Adjust regions is. After a google search nothing turns up.
here is my cpu output:

sh proc cpu sorted | e 0.00
CPU utilization for five seconds: 72%/49%; one minute: 69%; five minutes:
69%
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process
56 1458890966 8848611 164876 7.50% 4.92% 4.59% 0 Adjust
Regions


Following another thread suggested looking at mac address table:
sh mac-address-table count | i Space
Total Mac Address Space Available: 4968
--
sh platform tcam utilization

CAM Utilization for ASIC# 0 Max Used
Masks/Values Masks/values

Unicast mac addresses: 784/6272 81/582
IPv4 IGMP groups + multicast routes: 144/1152 6/26
IPv4 unicast directly-connected routes: 784/6272 81/582
IPv4 unicast indirectly-connected routes: 272/2176 146/1072
IPv4 policy based routing aces: 0/0 0/0
IPv4 qos aces: 528/528 18/18
IPv4 security aces: 1024/1024 57/57

Note: Allocation of TCAM entries per feature uses
a complex algorithm. The above information is meant
to provide an abstract view of the current TCAM utilization

Any help would be appreciated
Chris

Re: 3750 High cpu [In reply to]

The 'Adjust Regions' process is not an issue here. The real problem is the
interrupt part of the load (49%). That means your switch handles large
amount of traffic in software. Do you use IPv6 or other features that are
not supported by hardware in you current SDM profile?
