OVERVIEW
our application needs to receive ALL incoming traffic.
However, NIC drops packets with ether type 0x88A8:
MAC: ------ MAC Header ------
MAC:
MAC: Destination Address : 00 E0 ED 00 00 00
MAC: Source Address : 00 00 00 00 02 00
MAC:
VLAN: ------ VLAN Header ------
VLAN:
VLAN: Tag Protocol Identifier = 0x88A8
VLAN: Tag Control Information = 0x0000
VLAN: User Priority = 0
VLAN: Canonical Format Indicator = 0
VLAN: VLAN Identifier = 0 (0x000)
TEST
1. Setup:
a. Server: Manufacturer: LENOVO Product Name: ThinkServer RD650.
b. Nics firmware firmware-version: f4.33 a1.2 n04.42 e800018a6.
I40e: filename: /lib/modules/3.10.0-
229.11.1.el7.x86_64/kernel/drivers/net/ethernet/intel/i40e/i40e.ko
version: 1.3.47

author: Intel Corporation, <e1000-devel@lists.sourceforge.net>
rhelversion: 7.1
2. Test:
a. Setting ports in promiscuous mode (with ifconfig).
b. Sending traffic.
c. Check in ifconfig if “RX packets” increase.
3. Results
a. Test fail on stag tagged frames(frame above).
b. This packets have ether type 0x88A8, which are handled
differently by the NICS and in result dropping
them.
QUESTION
1. how to configure the NIC to forward all traffic?
