Filtering can provide an additional layer of wireless security. Filters can
be created to filter a protocol or IP port. Protocol filters prevent or allow
the use of specific protocols through the access point. Individual protocol
filters can be setup and enabled for one or more VLANs. MAC, Ethertype and IP
filters can be used to filter wireless client devices, users on the wired LAN,
or both
.
For
example, an SNMP filter on the radio port of the AP prevents wireless client
devices from using SNMP with the access point, but does not block SNMP access
from the wired LAN.
