8-18 Packet Filter

If the syntax is invalid, the filter is still added to the managed

list with a status of verify failed. To correct filter file errors, you

must make the changes to the original filter file using a text

editor, and re-TFTP the file to the NETServer flash memory.

You can then use the verify filter command to check the filter file

syntax. For more information about the verify filter command,

refer to Verifying Filter File Syntax on page 8-19.

To add a filter file to the list of managed filters, use the

following command:

add filter <filter_name>

Tip: It may be helpful to use the list files command to see files

successfully stored in the NETServer flash memory.

Removing a Filter from an Interface

To remove a filter that is assigned to an interface, use the

following command:

set interface <interface_name>

input_filter ""

output_filter ""

The “” value represents a null value and removes the defined

filter from the interface. For example, to remove an output filter

from an interface named eth:1, you would use this command:

set interface eth:1 output_filter ""

Removing a Filter from a User Profile

To remove a filter that is assigned to a user profile, use the

following command:

set user <user_name>

input_filter ""

output_filter ""

The “” value represents a null value and removes the defined

filter from the user profile. For example, to remove an input

filter from a user profile named john_d, you would use the

following command:

set user john_d input_filter ""
