Managing Filters Using CLI 6-39
Deleting a Packet Filter
Using CLI
To delete a specific packet filter, removing the filter file permanently from the
FLASH memory, use the CLI command
delete filter <filter_name>
Verifying Filter File
Syntax Using CLI
The verify filter command must be used if you make changes to a filter file that has
already been added to the managed list and re-TFTP it back to the router’s FLASH
memory (using the same filename). The verify filter file will check the filter syntax.
If the syntax is valid, no message is generated and the command prompt returns. If
the syntax is not valid, error messages are generated detailing the source of the
errors.
To verify a filter file, use the CLI command
verify filter <filter_name>
Showing Filter File
Contents Using CLI
To view the contents of an entire filter file that has been added to the managed
list of filters, use this command:
show filter <filter_name>
To display the contents of the filter file by protocol, use the CLI command
show filter <filter_name> protocol BR-ETH | IP | IP-RIP | IPX |
IPX-RIP | IPX-SAP
