Displaying and modifying system parameter default settings
The dest-mac mask | any parameter specifies the destination MAC address. The syntax rules are
the same as those for the src-mac mask | any parameter. Note that the 802.1x Authentication filter
(dot1x auth-filter) does not use the destination MAC address in the MAC address filter.
The filter-num command identifies the MAC address filter. The maximum number of supported MAC
address filters is determined by the mac-filter-sys default or configured value.
The dot1x auth-filter filter-list command binds MAC address filters to a port.
The following rules apply when using the dot1x auth-filter command:
• When you add filters to or modify the dot1x auth-filter, the system clears all 802.1X sessions
on the port. Consequently, all users that are logged in will need to be re-authenticated.
• The maximum number of filters that can be bound to a port is limited by the mac-filter-port
default or configured value.
• The filters must be applied as a group. For example, if you want to apply four filters to an
interface, they must all appear on the same command line.
• You cannot add or remove individual filters in the group. To add or remove a filter on an
interface, apply the filter group again containing all the filters you want to apply to the port.
If you apply a filter group to a port that already has a filter group applied, the older filter group is
replaced by the new filter group.
Displaying and modifying system parameter default settings
TurboIron X Series devices have default table sizes for the system parameters shown in the
following display outputs. The table sizes determine the maximum number of entries the tables can
hold. You can adjust individual table sizes to accommodate your configuration needs.
The tables you can configure, as well as the default values and valid ranges for each table, differ
depending on the device you are configuring. To display the adjustable tables on your device, use
the show default values command. The following shows example outputs.
Configuration considerations
• Changing the table size for a parameter reconfigures the device memory. Whenever you
reconfigure the memory on a device, you must save the change to the startup-config file, then
reload the software to place the change into effect.
• Configurable tables and their defaults and maximum values differ on IPv4 devices versus
IPv6-capable devices.
Displaying system parameter default values
To display the configurable tables and their defaults and maximum values, enter the show default
values command at any level of the CLI.
The following shows an example output of the show default values command.
