Hello everyone,

I am performing a traffic filtering experiment, and the traffic-filter on S7706 does not take effect. The configuration is as follows:

acl number 3000

rule 3 deny ip destination 172.17.107.0 0.0.0.255

rule 5 deny ip source 172.17.112.0 0.0.0.255 destination 172.17.107.0 0.0.0.255

//172.17.112.0---vlan312

//172.17.107.0---vlan307

traffic-filter vlan 312 inbound acl 3000

After this configuration, why the PC of vlan312 can still PING to vlan307?

Please help me!

Hi Qazik,

There is a problem with your configuration, rule 3 has denied all access to 172.17.107.0. Then the second rule 5 is meaningless. You should configure as follows:

acl number 3000

rule 5 deny ip source 172.17.112.0 0.0.0.255 destination 172.17.107.0 0.0.0.255

traffic-filter vlan 312 inbound acl 3000

I hope it helps!

Arrangement (order) of rules are incorrect.
Please remove rule 3
