If you are working on 16.04, the command format for adding firewall rule is as below;

p <pipeline_id> firewall add ipv4 <priority> <src ip><src ip mask><dst ip><ds tip mask><src_port_from><src_port_to><dst_port_from><dst_port_to><protocol><protocol_mask><port id>

The reason why your command is failing is because in 16.07 we have changed the command format for adding rule to firewall pipeline.

I guess you have configured 4 ports  (port  id 0 -3), so if this is the case, use right port id.

To learn the command format, please follow the code - ip_pipeline/pipeline/pipeline_firewall.c
