Question about a process of ACL on Cisco7301

Hi,

I have a question of processing ACL.

Catalyst6500/4948/3750 is processed by Hardware(TCAM) of ACL.

Is Cisco 7301 processed by Hardware(ASIC)? or Software(CPU use)??

Regards,

ACL processing on routers is done in software as routers do not have dedicated ASIC's for this sort of thing.

By software.

As both Jon and Paolo have noted, the 7301 does everything in software (since it uses the NPE-G1). However, if you were using a 7304 with either the NSE-100 or NSE-150, its PXF Turbo ACL feature, I believe, does some ACL hardware acceleration.

All,

Thank you for quick reply.

The difference between 7301 and 7304 has been understood well.

Regards,
