Hi i hope someone has some good ideas, to what can be wrong here.
I got 2 Catalyst 6500 running as collapsed Data center core / distribution. And then i have some different types of access switches down under Nexus 5K and some some 3750E and 3560.
All the sudden 2 of the 3560 and 1 3750E cpu´s rised from 10 % to 87% with proces HLFM address learning nothing has been changed. And i only see it on some of my 3560 and 3750E i also got another 3750E where everything is normal.
Anyone got some ideas to what can cause this issue ? the high cpu load has been steady since yesterday.
I have attached show proc cpu. I am running on latest ios for 3560 and 3570E ( 12.2(55)SE8
