Symptom:
When applying a feature (such as an IPv6 access-list) to an interface or following a chassis reload, the ACL may fail to be programmed in TCAM with the following error:

%EARL_CM-SW1-5-NOCAPMAP: No free capmap entry available
%FMCORE-SW1-4-RACL_REDUCED: Interface Vlan100 routed traffic will be software switched in ingress direction.
        L2 features may not be applied at the interface

Conditions:
This is specific to any EARL8 forwarding engine:
- Supervisor2T, 6T
- 6800's (example: 6880-x or 6840-x based switches) 

This occurs when utilizing multiple ACL based features in the same direction that use a large number of L4Ops (greater than 9) .  L4Ops within an access-list include the following:
Expandable:
- gt (greater than)
- lt (less than)
- neq (not equal)
- range
Non-expandable:
- matching on ToS (DSCP or IPP)
- matching on IP packet length
- matching on TCP flags (ex. established)
- TTL
- ipv6 extension header or ip options

Note, hardware restriction limits any single feature to <=9 non-expandable l4ops.  More than 9 expandable l4ops can be used by 'expanding' the match logic into multiple entries in TCAM.

Example:
1) IPv4 ACL applied to an interface that utilizes >=9 L4OPs (expandable or non-expandable)
2) Attempt to apply an IPv6 ACL to the same interface that utilizes >=1 L4OP

The IPv6 will fail to be applied to the interface. 

Note - All IPv6 ACLs require a minimum of 1 non-expandable L4OP to be applied in hardware, regardless of the permit/deny statements within the ACL.
