What is the command to write port based SA's using ip xfrm state.

iam using below command for writing SA's : 
ip xfrm state add src 192.168.1.20 dst 192.168.1.5 proto esp spi 
0x354cb04b mode tunnel reqid 16385 replay-window 32 auth sha1 
0xecf02a5cf6568556e1bdcd961c7ec3f92afd01cc enc aes 
0x5c0cfa9672ce67ba545b593076dfb278 sel src 0.0.0.0/0 dst 0.0.0.0/0  

Thanks in advance

he pfkey / xfrm interface throws them away

i fixed racoon to send the port numbers and they were ignored

IIRC I tested port selectors in SA a few years ago using "ip xfrm"
and they worked fine. The xfrm interface doesn't ignore them 
(copy_from_user_state()), I think the pfkey interface also doesn't.

Please try configuring them manually using "ip xfrm state",
I'm pretty sure the bug is actually in racoon.

Usually you don't want port-based SAs but port-based policies.
The syntax is described in "ip xfrm policy help".  Look for sport
and dport.
