Egress RACL 在TCAM中不能合并,所以如果调用在SVI会导致TCAM资源消耗很快。建议汇总ACL条目或改用ingress RACL。
TCAM resources are shared in the following scenarios:
When a routed ACL is applied to multiple switched virtual interfaces (SVIs) in the ingress direction
When a routed ACL is applied to multiple physical Layer 3 interfaces in the ingress or egress direction
TCAM resources are not shared in the following scenarios:
VACL (VLAN ACL) is applied to multiple VLANs.
Routed ACL is applied to multiple SVIs in the egress direction.
TCAM resources are not shared when a routed ACL is applied to multiple SVIs in the egress direction.
