in switch 2960s ( c2960s-universalk9-mz.122-55.SE5 ) , i want to marking the trafic between two hosts ( Data replication ), i choose to use " mac access-list" to classify my trafic before apply the policy marking . but did'nt work . can you help me plz
On 2960-S switches, MAC ACLs apply only to non-IP traffic. An IP packet can only be matched by an IP ACL. Therefore, if the data replication traffic is IP-based, you can not use MAC ACLs, rather, you must modify your configuration to use IP ACLs.
yes , the data replication is IP-based , but the reason why I made mac ACL is that the IP ACL did not work, , i dont' any match in ACL and in Policy-map when i do IP ACL ( really i do the IP-ACL thousand times but in switch I do not understand why it does not work anymore ) .
1 ) is there something to activate in the switch so that it support IP ACL ??
2 ) is what I apply the QOS policy in interface layer 2 or i must applying in layer 3 interface to supporting IP ACL ??
