Hi.

I'm trying to configure some IOS ACLs on 6500 VLANs (6509/PFC/MSFC), but the
following messages (I've appended the descriptions) appear:

FM-4-TCAM-LOU: Hardware TCAM LOU capacity exceeded
Explanation This message indicates that the hardware TCAM can only handle
up to nine logical operations per interface and up to 64 logical operations
in total. The hardware TCAM does not have the capacity to handle the number
of logical operations used with the configured ACLs.

Recommended Action Reduce the use of logical operations in the ACLs.

FM-4-TCAM-CAPMAP: Interface [chars] hardware TCAM LOU usage capability
exceeded
Explanation This message indicates that the hardware TCAM can only handle
up to nine logical operations per interface and up to 64 logical operations
in total. The hardware TCAM does not have the capacity to handle the number
of logical operations used with the configured ACLs on this specific
interface; [chars] represents the interface.

Recommended Action Reduce the use of logical operations in the ACLs.

What exactly is considered a logical operation in ACLs ?
