Network Access (MAC Address Authentication)
– 311 –
â—† This parameter applies to authenticated MAC addresses configured by the MAC
Address Authentication process described in this section, as well as to any
secure MAC addresses authenticated by 802.1X, regardless of the 802.1X
Operation Mode (Single-Host, Multi-Host, or MAC-Based authentication as
described on page 280).
â—† The maximum number of secure MAC addresses supported for the switch
system is 1024.
Example
Console(config-if)#network-access aging
Console(config-if)#
network-access
mac-filter
Use this command to add a MAC address into a filter table. Use the no form of this
command to remove the specified MAC address.
Syntax
[no] network-access mac-filter filter-id
mac-address mac-address [mask mask-address]
filter-id - Specifies a MAC address filter table. (Range: 1-64)
mac-address - Specifies a MAC address entry. (Format: xx-xx-xx-xx-xx-xx)
mask - Specifies a MAC address bit mask for a range of addresses.
Default Setting

Command Mode
Global Configuration
Command Usage
â—† Specified addresses are exempt from network access authentication.
â—† This command is different from configuring static addresses with the mac-
address-table static command in that it allows you configure a range of
addresses when using a mask, and then to assign these addresses to one or
more ports with the network-access port-mac-filter command.
â—† Up to 64 filter tables can be defined.
â—† There is no limitation on the number of entries that can entered in a filter table.
Example
Console(config)#network-access mac-filter 1 mac-address 11-22-33-44-55-66
Console(config)#
