Chapter XX. Classification and Filtering
Chelsio Unified Wire for Linux 291
The above filter rule will switch all the packets matching above 4 tuple from Chelsio port 0 to
Chelsio port 1. Remaining packets will be sent to the host.
3.3. Listing Filter Rules
•
To list the Hash/DDR filters set, run the following command:
[root@host~]# cat /sys/kernel/debug/cxgb4/<bus-id>/hash_filters
•
To list the both LE-TCAM and Hash/DDR filters set, run the following command:
[root@host~]# cxgbtool ethX filter show
3.4. Removing Filter Rules
To remove a filter, run the following command with cap maskless parameter and corresponding
filter rule index:
[root@host~]# cxgbtool ethX filter <index> <delete|clear> cap maskless
3.5. Filter Priority
By default, Hash/DDR filter has priority over LE-TCAM filter. To override this, the LE-TCAM filter
should be created with
prio option. For example:
[root@host~]# cxgbtool ethx filter <index> action <pass/drop/switch> prio 1
Where index is a positive integer set as filter id. 0-495 for T5 adapters and 0-63 for T6 adapters.
For more information on additional parameters, refer cxgbtool manual by running
the
man cxgbtool
command.
Note
•
Filter rule index can be determined by referring the “hash_filters” file located in
/sys/kernel/debug/cxgb4/<bus-id>/.
•
For more information on additional parameters, refer cxgbtool manual by runing
the
man cxgbtool
command.
