Scenario

Frame filtering involves the configuration of white list, static blacklist and dynamic blacklist. When AP receives a data frame, it will check the MAC address of this data frame. The process of frame filtering is shown below:

                                             

Figure flow of frame filtering

I. Requirements

Configure white list in WIDS configuration mode. When an entry exists in the white list, the corresponding client will pass frame filtering.

   

II. Configuration Tips

Configure whitelist based on SSID (When an entry exists in the white list, the corresponding client will access to ssid)

Configure blacklist based on SSID (When an entry exists in the black list, the corresponding client will be denied to access to ssid)

IV. Configuration Steps

Configure whitelist based on ssid:

WS5302(config)#wids

WS5302(config-wids)#ssid-filter whitelist mac-address 6809.27b0.169f in ruijie       ----->6809.27b0.169f is allowed to access to SSIDruijie

WS5302(config-wids)#ssid-filter whitelist max 256----->adjust whitelist capacity (range from 1-256,  optional config)

Configure blacklist based on ssid:

WS5302(config)#wids

WS5302(config-wids)#static-blacklist ssid-mac  6809.27b0.169f in ruijie ----->6809.27b0.169f is denied to access to SSIDruijie

WS5302(config-wids)#ssid-filter blacklist max 256 ----->adjust blacklist capacity (range from 1-256,  optional config)

V. Verification

1.      When an entry exists in the white list,  the corresponding client will access to ssid,STA MAC:(6809.27b0.169f、 8ca9.829a.b1ea)
