Impact of ACL on C6509 CPU utilization

[Zeeshan Siddiqui]

All,

Can you please help with the following

We plan to implement a large number of ACL on our Distribution switch which is a HSRP pair of 6509C switches running on

sup-bootflash:s72033-psv-mz.122-18.SXD3.bin

WE need to divide the Network in three layers

unsecure layer

Proxy layer

Secure layer

We have approximately 250 vlans on the our distribution switches and plan to implement 15 ACL on different vlans Each ACL can contain upto 30 lines or less.

basic ACL example we will be applying on different vlan

vlan 200

ip access-group test123 in

My question is

Can these ACL on a vlan can have a massive impact on the 6509 CPU ?

Any Response is much appreciated.
