we has some S2300 switches and found abnormal on it, trying to filter out packet wih intruder source MAC:


acl number 4005

 rule 10 deny source-mac 0017-df00-0000 ffff-ff00-0000

 rule 100 permit


interface Ethernet0/0/21

 traffic-filter inbound acl 4005 rule 10

traffic-filter inbound acl 4005 rule 100

 undo lldp enable

 port-isolate enable group 1

 multicast-suppression 2

 broadcast-suppression 1


but such packet S23 can not drop, intruder send  such packet to Eth/0/21 and packets succefully out from Gigabitethernet uplink, , any undocumented restriction at S23 ? May be it check ether-type frame as PPPoE and fail apply traffic-filter ?

Hello Kolli,
Please trying remove the parameter rule when assigning the traffic filter under the interface view, or replace the traffic filter with traffic policy. When the deny action is defined in the ACL rule associated with the traffic-filter command, the ACL rule can only be associated with the traffic-mirror (interface view), traffic-mirror (system view), traffic-statistic (interface view), or traffic-statistic (system view) command. If the ACL rule is associated with other simplified traffic policies, the simplified traffic policies may not take effect.

Hi,
I'm not sure if Layer 2 ACLs have such a limitation. You can try to apply the traffic filter to a blank interface to check whether common packets (non-PPPoE packets) can be filtered.
