Set custom topology for forwading packets by making the given two ports as pair, in custom topology the active ports will be the defiend in custum-topo only.
This command will be useful in testing, when special topology is needed. usage: testpmd> set custom-topo (port_id_1) (port_id_2) Signed-off-by: Wisam Jaddo <wis...@mellanox.com> --- app/test-pmd/cmdline.c | 49 +++++++++++++++++++++++++++++ app/test-pmd/config.c | 41 ++++++++++++++++++++++++ app/test-pmd/parameters.c | 6 ++-- app/test-pmd/testpmd.h | 8 ++++- doc/guides/testpmd_app_ug/testpmd_funcs.rst | 8 +++++ 5 files changed, 109 insertions(+), 3 deletions(-) diff --git a/app/test-pmd/cmdline.c b/app/test-pmd/cmdline.c index 9615670..9d48048 100644 --- a/app/test-pmd/cmdline.c +++ b/app/test-pmd/cmdline.c @@ -466,6 +466,9 @@ static void cmd_help_long_parsed(void *parsed_result, "set eth-peer (port_id) (peer_addr)\n" " set the peer address for certain port.\n\n" + "set custom-topo (port_id_1) (port_id_2)\n" + " set custom topo.\n\n" + "set port (port_id) uta (mac_address|all) (on|off)\n" " Add/Remove a or all unicast hash filter(s)" "from port X.\n\n" @@ -7649,6 +7652,51 @@ cmdline_parse_inst_t cmd_set_fwd_eth_peer = { }, };
