Ethernet Type Filter – Controls checks on the Ethernet type of all incoming and
outgoing Ethernet packets against the protocol filtering table. (Default: Disabled)
• Disabled: Access point does not filter Ethernet protocol types.
• Enabled: Access point filters Ethernet protocol types based on the configuration
of protocol types in the filter table. If the status of a protocol is set to “ON,” the
protocol is filtered from the access point.
Note: Ethernet protocol types not listed in the filtering table are always forwarded by the
access point.
CLI Commands for Bridge Filtering – Use the filter local-bridge command from the
global configuration mode to prevent wireless-to-wireless communications through
the access point. Use the filter ap-manage command to restrict management
access from wireless clients. To configure Ethernet protocol filtering, use the filter
ethernet-type enable command to enable filtering and the filter ethernet-type
protocol command to define the protocols that you want to filter. To remove an entry
from the table, use the address filter delete command. To display the current
settings, use the show filters command from the Exec mode.
