We are experiencing constant High CPU on 3750 switches due to vlan 1
Further info - we have a pair of Alteon load balances between the 3500 and 3750's which is also running vlan 1. Could this produce high CPU ? (Appreciate vlan 1 usage not best practice but ignore that for now). We run sho proc cpu sorted and see vlan manager proc running cpu at 90% constantly. How would vlan ID manger process push cpu to 90% and hold it there ? - appreciate any ideas on this.
