Hey guys,
I have a 7500 , with dual RSP 4 / 256 MB RAM.
The router has 1 VIP 4-80 , and that VIP has two PAs
1) Fast Eth
2) ATM
Customers connect to Fast Eth , on it's subinterfaces and almost all the
Fast Eth subinterfaces have CAR being implemented ( may be around 250
subinterfaces )
And ATM is used to connect to the SP's network , it also have around 80 VCs.
Router runs around 12 VRFs but no MPLS ( VRFs are connected back to back
)
Now the issue is the cpu run at around 80 % on average ,and the IP Input
Process is eating 25/30 % of the processes.
I have trying to implement all the fast , CEF and DCEF switching , still it
seems lot of traffic is process switched.
VIP's cpu runs at only 20 %
Any ideas which will help me to releive the CPU ?
Cheers
Vishal
