Prerequisites: You have started the container, and followed the steps described in the section Useful extra software to install in the container.
P4 program add_on_miss1.p4 has different logic for deciding whether
to add an entry to table ct_tcp_table. It also uses the extern
function set_entry_expire_time in the hit action for ct_tcp_table
to set the expire time of an entry when a packet matches an existing
entry, depending upon the TCP flags of the packet, which has the
additional side effect of restarting the expire timer of the entry.
Thus data packets continuing to match the entry will keep it from
being deleted, unlike add_on_miss0.p4.
In the base OS:
cp -pr ~/p4-guide/ipdk/add_on_miss1/ ~/.ipdk/volume/This only needs to be run in the container once:
source $HOME/my-venv/bin/activate
export PYPKG_TESTLIB="/tmp/testlib"In the container:
BASENAME="add_on_miss1"
cd /tmp/${BASENAME}
/tmp/bin/compile-in-cont.sh -p . -s ${BASENAME}.p4 -a pna
cd /tmp/${BASENAME}/out
/tmp/bin/start-infrap4d-and-load-p4-in-cont.sh ${BASENAME} ${BASENAME}
