Problem Description

Packet filtering does not take effect

Process Analysis

The packet filtering policy is applied under the wireless service template, and the relevant configuration on the AC:

wlan service-template 1

ssid lab

vlan 1007  

packet-filter 3000 outbound

packet-filter 3000 inbound

service-template enable

acl number 3000

 rule

10 permit ip source 172.X.X.X 0.0.255.255 destination 172.X.X.X 0.0.0.127

 rule

1000 deny ip

After the configuration is complete, use the terminal to connect to the wireless, and test that the ip address not in the rule 10 can still be pinged.


Solution

 Packet filtering based on wireless service templates requires ACL rules to be configured on the AP, regardless of whether it uses centralized forwarding or local forwarding, which can be configured by map file distribution.
