Dear Members,
Is there any problem with 'Lagg-LACP on Intel Fortville NIC on FreeBSD
HOL (11.0 Current)' setup ?
Your help is greatly appreciated.
*Setup Information : *
- Machine (Intel Taylor Pass) is running FreeBSD-HOL (11 current)
- Machine has 'Intel Fortville NIC (Intel Ethernet Controller XL710)'
installed with special firmware to support four 10Gbps ports with
breakout cable
- Breakout cable is used with one of the 40GB ports which creates four
10GB ports
- All four 10Gbps ports are connected to Dell Force 10 Switch
- Lagg-LACP has been configured on all four 10GB ports of the Machine
and on Switch ports as well
*Problem Statement :*
# When machine sends an Arp-request then interface does not receive
Arp-reply
- Arp request sent by the machine is successful
- Switch is able to get Arp broadcast request sent by the machine
- Switch sends back unicast Arp-reply to machine
- But still driver does not receive Arp-reply
# Even after adding static Arp entry in machine's Arp table, ping fails
# Configured same MAC address on all 4 interfaces which are part of
Lagg, still ping fails
Is there any problem with MAC filtering ?
*Workaround : *
- After putting Lagg interface in promiscuous mode, network interface
seems to work properly.
*Platform Information :*
Machine - Intel Taylor Pass server board
OS - FreeBSD HOL (11.0 Current)
NIC - Intel Fortville NIC (Intel Ethernet Controller XL710) - Find more
information as below
Switch - Dell Force 10 Switch
