i40e MAC filter hash state failed

Hi,

My NIC is dropping the packets destined to the following MAC and VLAN ID.

I got the following error from the driver when i tried to dump the mac filter hash state in NIC.

[3214997.759285] i40e 0000:19:00.3:     mac_filter_hash: 33:33:ff:43:75:3c vid=2056, state FAILED

[3214997.759293] i40e 0000:19:00.3:     mac_filter_hash: 33:33:ff:43:75:3c vid=2200, state FAILED

[3214997.759300] i40e 0000:19:00.3:     active_filters 1946, promisc_threshold 1974, overflow promisc ON

Using the “ethtool” I could confirm that the device is receiving the packets, but not sending it to upper layers.

port.rx_unicast >>>> This counter is incrementing

Has someone seen similar issue before?

Does this means that we are reaching the scale limit in terms of number of hash entries?

What does the “active_filters” and “promisc_threshold” means?

Thanks & Regards,

Santosh

Hi @SantoshSingh,

Thank you for sharing the information.

Firstly, based on the network adapter/controller shown, may I clarify with you if it is embedded to Cisco UCS’ system board?

Secondly, the i40e driver and linux kernel version are not up to date. May I know if you have tried update to later version if it makes some differences?

Thank you.

Hi  @BY _Intel,

Thanks for your reply.

Yes

Secondly, the i40e driver and linux kernel version are not up to date. May I know if you have tried update to later version if it makes some differences?

We started seeing this issue with a driver upgrade, can you please point me to the latest version of the driver?

What is the scale Limit, in terms of number of Entries in MAC FILTER HASH Table?

Also, any Idea on the below message -

[3214997.759300] i40e 0000:19:00.3:     active_filters 1946, promisc_threshold 1974, overflow promisc ON
