• MAC Address: Specifies a MAC address to filter, in the form xx-xx-xx-xx-xx-xx.

• Permission: Adds or deletes a MAC address from the filtering table.

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.

Ethernet Type Filter – Enables or disables Ethernet filtering on the port. (Default:

Disabled)

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.
