The DHCP Relay issue still has not been resolved.
The issue was DHCP Offer packets that being sent from the DHCP server are not
reaching the client.
Setup:
DHCP Client: IB Side Ubuntu OS with ConnectX3 FW ver 2.35.5000, Mellanox
OFED 3.2-1.0.1
DHCP Server: ETH Side Win2012 R2 with ConnectX3 FW ver 2.35.5000, WinOF 5.10
SX GW, MLNX_OS ver 3.4.3002
Looking at the traffic capture I can see packets are coming from the Windows
server towards the switch, but never leaving it.
Please refer to the following traffic capture files attached to the case:
Ibdump_dhcp – capture of ib0
Dhcp.pcap – port mirroring of the ETH port connected to the Windows
Dhcp_win2012 - wireshark capture of the windows dhcp server
Setup details is mentioned & marked above.
Setup:
IB Side: DHCP Client Ubunutu 14.04, OFED 3.2-1.0.1.1, CX3 2.35.5000
(10.7.55.193)
ETH Side: DHCP Server Win2012 R2, WinOF 5.10, CX3 2.35.5000
(10.7.55.190)
SX1036 GW: MLNX_OS ver 3.4.3002
Before installing the PPA
DHCP client sends discover, DHCP server send offer, however the packet never
reach the client, bootp flag is Unicast
