DESCRIPTION

On HPE systems running Red Hat Enterprise Linux 7.5, after changing the Maximum Transmission Unit (MTU) size to higher than 1500, the HPE Gigabit Ethernet Adapters with HPE Intel IGB Driver version 5.3.5.19 listed in the Scope section below, are unable to receive packets.

SCOPE

Any HPE systems running Red Hat Enterprise Linux 7.5 and configured with any of the following HPE Gigabit Ethernet Adapters:

  • HP Ethernet 1Gb 2-port 361i Adapter
  • HP Ethernet 1Gb 2-port 361T Adapter
  • HP Ethernet 1Gb 2-port 363i Adapter
  • HP Ethernet 1Gb 4-port 366FLR Adapter
  • HPE Ethernet 1Gb 4-port 366i Communication Board
  • HP Ethernet 1Gb 4-port 366T Adapter

RESOLUTION

As a workaround, use an MTU size 1500 (or lower).

To specify an MTU size, using a command similar to the following:

ifconfig interface_name mtusize size

This is targeted to be resolved in a future version of the HPE Intel IGB driver.

This advisory will be updated when additional information is available.
