Attention:
If the block filter is chosen to setup, all other packets that have no relation with the
block filter will pass through. If the pass filter is setup, however, all other packets that have no
relation with the pass filter will be blocked. Therefore, the pass filter requires an additional filter
that can take care of those packets that are not under the control of the pass filter.
Viewing the filters
To display the filters, type the following command:
COMMAND
(conf)# show filter
Applying a filter to a interface
To control which packets will be allowed to cross the interface, you specify the interface
as follows:
COMMAND
(conf)# filter port <ifname>
Parameters
<ifname> - Interface name
A filter applied to the interface takes effect immediately. Also, if you change any of the
filter conditions, new or changed conditions are applied immediately.
Usage Examples:
(conf)# filter port lan
To stop applying a filter to the interface, type the following command:
COMMAND
(conf)# filter port none
Deleting a filter
To delete a filter condition, use the following command:
COMMAND
(conf)# filter in|out <num> delete
Parameters
<num> - defined filter’s number
