usage setkey delete option for ipsec

Hi,

My intention is to delete SADB entries one by one using the setkey
delete option.
I have the follwoing entry in my setkey.conf

delete fec2::1[55001] fec2:0:f675:803a::4[55002] esp 4101;

But when running $setkey -f setkey.conf
it throws scuh an error ...
line 1: syntax error at [[]
parse failed, line 1.

If I remove the port values [55001] and [55002] then setkey says
"The result of line 1: No such process."

My $setkey -D
output is shown below

setkey -D

Could someone point out what I might be doing wrong or the right way
to pass the "delete" option an ipv6 address along with the port in
square brackets.

Thanks and regards,
Jack.
