I have couple of 4500 switches which are running high CPU. Though i know it is process Cat4k Mgmt LoPri which is eating up CPU cycles, i am unable to determine what exactly is the root cause and how to fix it.
Below are the commands for your reference. How do i see which packets are being sent to CPU and what interface is sending them and why.

From the outputs you provided I suspect packets are being software processed Input Acl punted packets are being dropped. These could be control packets like IGMP, OSPF etc. Or there is a ACL defined that is logging. If the problem is happening now can you collect show platform health and show platform cpu packet statistics?
If it is traffic being punted to the CPU try using the following debug: (built-in-sniffer)
- debug platform packet all receive buffer (safe to use in high CPU condition that is what it is built for)
- show platform CPU packet buffered to see what packets are being punted.
The output will provide src / dst and rx interface, etc...
Here is a whitepaper on TS high CPU on the 4500. Refer to the built in sniffer tool for more details.

Thanks for the reply Dale. I have few further queries.
Can you let me about this output from show plat cpu packet stat all.Apart from Input Acl Fwd event, i can see event Sa Miss and Packets Dropped In Processing by reasons NoDstPorts and Tx Mode Drop

Sachin,
The SA Miss is a packet flooded in the vlan and a copy sent the CPU for mac learning. The Tx mode drop (almost exact match to the amount of drops for SA MIss ) is that same packet getting dropped. Since the packet was already bridged by hardware, software drops the packet after doing source learning. The NoDstPorts are packets that cannot be forwarded. Example TTL=1 or hairpinned traffic that cannot be forwarded out the same interface it was received.
I can see from the outputs you're running the command when the CPU is normal. These outputs will help determine the root cause while the problem is happening. From the information so far I think it is best you get a idea of what traffic is punted to the CPU when running high. The debug packet all recieve buffer would be the ideal tool to use. You can also do an inband span and monitor all traffic to the CPU.
Once you identify what traffic is causing the problem it will be much easier to identifiy the root cause. Right now there isn't enough information to tell.
Take Care,
Dale
