2.2. Creating Filter Rules
Network driver ( cxgb4 ) must be installed and loaded before setting the filter rule.
i.
If you haven’t done already, run the Unified Wire Installer with the appropriate T5/T4
configuration tuning option to install the Network Driver.
ii. Next, run the following command to load the network driver:
[root@host~]# modprobe cxgb4
iii. Now, create filter rules using cxgbtool :
[root@host~]# cxgbtool ethx filter <index> action [pass/drop/switch]
Where,
ethX : Chelsio interface
index : positive integer set as filter id
action : Ingress packet disposition
pass : Ingress packets will be passed through set ingress queues
switch : Ingress packets will be routed to an output port with optional header rewrite.
drop : Ingress packets will be dropped.
2.2.1. Examples

Drop action
[root@host~]# cxgbtool ethX filter 0 action drop fip 192.168.1.5
The above filter rule will drop all ingress packets from IP 192.168.1.5

Pass action
[root@host~]# cxgbtool ethX filter 0 action pass lport 10001 fport 355
queue 2
In case of multiple filter rules, the rule with the lowest filter index takes higher
priority.
