Hi,
I’ve got problems with HP NC550SFP NIC
(http://www.emulex.com/products/ethernet-networking-storage-connectivity/ethernet-networking-adapters/hp-branded/nc550sfp/overview/
)
Setup information:
I’m intended to use this system for traffic monitoring:
switchport configured for traffic mirroring to 10 Gbit port of NC550SFP
adapter.
Adapter is detected by oce(4) driver:
$ dmesg
…

Problem:
It is switched to promiscuous mode:
$ ifconfig oce0
oce0:
flags=68143<UP,BROADCAST,RUNNING,PROMISC,MULTICAST,PPROMISC,MONITOR>
metric 0 mtu 1500
options=407bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,VLAN_HWFILTER,VLAN_HWTSO>
ether 10:60:4b:01:12:48
nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
media: Ethernet autoselect (10Gbase-SR <full-duplex>)
status: active
Via tcpdump I see only broadcast frames.
Via sysctl I see constantly increasing error counter:
dev.oce.0.stats.rx.err.address_match_errors: 124171960
It seems that all unicast frames not addressed to adapter's MAC-address
are dropped at hardware, which means that promiscuous mode is not
working as intended.
Behavior is similar under 10.1 RELEASE, and 11.0-CURRENT (FreeBSD
11.0-CURRENT #0 r284443). GENERIK kernel.
The same box works fine under Linux with be2net driver, so It’s
definitely not a hardware problem and seems like a problem with FreeBSD
oce(4) driver
Any suggestions?
Thanks in advance.
Best regards,
Sergey Akhmatov
