[dpdk-dev] Pktgen DPDK net bonding mode 4 802.3AD (LACP) not working with BIGIP trunk with LACP enabled

[Vincent Li]

Hi,

I have direct two cable connections between Pktgen DPDK box and BIGIP

this is a problem I am not sure if it Pktgen, or the DPDK net bonding mode
4 LACP, or the BIGIP trunk with LACP enabled issue, I am hoping someone
here have more clue and give me some direction on how to trouble shoot
this. I am suspecting there might some issue between DPDK net bonding
8023ad mode 4 and BIGIP trunk LACP mode. I turned
on CONFIG_RTE_LOG_LEVEL=RTE_LOG_DEBUG and
defined RTE_LIBRTE_BOND_DEBUG_8023AD
in drivers/net/bonding/rte_eth_bond_8023ad.c hoping getting more debug
output in Pktgen, I could not see any debug output for 8023ad protocol.


packet tx/rx works :

1 Pktgen with DPDK net bonding mode 1, 2, 3, 5
2 BIGIP trunk with LACP disabled (trunk port status UP)

packet tx/rx failed:

1, Pktgen with DPDK net bonding mode 4 802.3AD
2, BIGIP trunk with LACP enabled (trunk status is DOWN)

or
1, Pktgen with DPDK net bonding mode 4 802.3AD
2, BIGIP trunk with LACP disabled (trunk status is UP)

my end goal is to achieve 10G < througput < 20G with Pktgen DPDK net
bonding with Intel 82599 to load test BIGIP, so far with bonding mode 1,
2,3, 5, I am unable to achieve throughput > 10G.

I am not going to be much help as I do not and have not used BIGIP.

I assume you have the Pktgen that supports bonding mode 4. The previous Pktgen version would not call tx_burst() unless it had something to send, which the bonding driver requires tx_burst() with zero packets at least at a given interval. The latest versions do call tx_burst() with zero pkts at least within the needed timing.

 --vdev=net_bonding0,mode=4,xmit_policy=l34,slave=0000:04:00.1,slave=0000:04:00.0
-- -P -m [0:1-7].2

also I am not sure where net bonding  debug log goes as I added

#define RTE_LIBRTE_BOND_DEBUG_8023AD 1

in drivers/net/bonding/rte_eth_bond_8023ad.c and the code has following

#ifdef RTE_LIBRTE_BOND_DEBUG_8023AD
#define MODE4_DEBUG(fmt, ...) RTE_LOG(DEBUG, PMD, "%6u [Port %u: %s] " fmt,
\
                        bond_dbg_get_time_diff_ms(), slave_id, \
                        __func__, ##__VA_ARGS__)
