Hi,
We have a high CPU usage at about 2.5Gbps traffic on an interface
The CPU hits 70% at its peak time. We are needing to increase the traffic by another 2Gbps but are worried the CPU will cap out at 100% during this period.
We have an estimated 460 active PPPOE sessions on the router at peak and this will increase.
Each PPPOE session has a queue which a dynamic simple queue.
Very minor firewall rules. mainly for radius access and remote access.
No NAT or mangle rules on the router.OS version 6.48.2
No fast path or connection tracking
No BridgeRouter has 2 X BGP peers and the peers are to route reflectors.
OSPF on 2 VLANs
Can anyone offer advice as to why the CPU would be so high and if the router is just not capable or we need to look and new router OS.
I have attached some screenshots of all CPU's being utilised at 1.6Gbps.
thank you
