I have configured a simple WWW load balancing between two servers on IOS 12.2(33)SXI1 running on VSS:
It is doing server NAT translation. I though this was done in hardware:
ip slb serverfarm WW
ip slb vserver PROXY_VIP
virtual 18.104.22.168 tcp www
From the moment i enable this -> CPU shoots to 100%, IP INPUT process is highest.
even with less than 10 sessions to the VIP
Is this because of the NAT ?
PS. The VLAN 1.1.1.x is used for other servers also. So it has some heavy background traffic also. I hope not all traffic is punted to the CPU for the NAT ?
