15.5.2 ACL Troubleshooting

&

The check of list entris in ACL is a top-down behavior, once one entry is mached, the check will be

finished immediately;

&

Only when there is no ACL binded or no ACL entry mached on the special direction of the port, the

default rules will be used;

&

Each port ingress can bind one MAC-IP ACL or one IP ACL or one MAC ACL;

&

Each port egress can bind one MAC-IP ACL or one IP ACL or one MAC ACL

&

When two sets of ACL are binded to the ingress and egress simultaneously, the priority of the

egress rules is higher than that of ingress rules; in the same set of ACL, the earlier the rule is
configurated, the higher its priority is;

&

When one ACL is binded to egress direction of the port, it can only include deny list entries;

&

Only the interfaces on the MASTER switch can support the binding of ACL;
