Top Forums UNIX for Advanced & Expert Users Changing single path NIC to a teamed connection in same subnet Post 303039505 by rbatte1 on Tuesday 8th of October 2019 08:30:45 AM

This appears to be a conflict between the server and the network switches all along. We have redefined them as LACP balanced connections and later the network team have done the same to the switch ports. This broke everything because there was still the default route going out on the old card which had been configured by the network team to be in the team. I removed the default route from that port and hey-presto, I've got on to the new IP address properly with data being returned so a proper connection could be established.

I have then reconfigured the now redundant link to be part of the team and restarted the network services. I now have multiple LACP balanced active links.



For anyone else who may find this thread, I have two cards with four ports, so eight possible eno interfaces. Only 1, 2, 5 & 6 are cabled, so the full commands I used to bond them all together are:-
Code:
nmcli con add type team con-name team0 ifname team0 config '{"runner": {"name": "loadbalance", "tx_hash": ["eth", "ipv4", "ipv6"], "tx_balancer": {"name": "basic"} } }'
nmcli con mod team0 ipv4.addresses '10.102.16.13/24' ipv4.method manual
nmcli con add type team-slave ifname eno2 con-name team0-eno2 master team0
nmcli con add type team-slave ifname eno5 con-name team0-eno5 master team0
nmcli con add type team-slave ifname eno6 con-name team0-eno6 master team0

A new MAC address is created for the team and each bonded interface gets the same MAC address.

After the original connection was redundant, I added it to the group with this command and this edit:-
Code:
nmcli con add type team-slave ifname eno1 con-name team0-eno1 master team0
sed -i 's/ONBOOT="yes"/ONBOOT="no"/'  /etc/sysconfig/network-scripts/ifcfg-eno1

Verification commands:
Code:
ip ad s
teamdctl team0 state                        (and variations from this)
nmcli -p
ethtool -S eno1                             (or eno2, eno5 & eno6)


I hope that this is useful to someone, but at least I have it documented for myself too! Smilie


Kind regards,
Robin
