NIC Teaming on Ubuntu 17.10 via netplan
Attempting to NIC team on Ubuntu 17.10 using netplan:
network:
version: 2
ethernets:
switchports:
match:
macaddress: 00:15:5d:ec:d3:07
macaddress: 00:15:5d:ec:d3:08
wakeonlan: true
bridges:
bond0:
interfaces: [switchports]
addresses: [172.30.1.10/18]
gateway4: 172.30.0.1
After applying cannot ping gateway or ping Ubuntu server from other network nodes. My hunch is I'm missing something simple but reading docs and other examples I'm at a loss :/
Here's ip addr show
:
[...]
2: eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 00:15:5d:ec:d3:07 brd ff:ff:ff:ff:ff:ff
3: eth0: <BROADCAST,MULTICAST,LOWER_UP> mtu 1500 qdisc mq master bond0 state UP group default qlen 1000
link/ether 00:15:5d:ec:d3:08 brd ff:ff:ff:ff:ff:ff
4: bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000

Update 1:
Changes bridges
to bonds:
as Mark Wagner pointed out.
Pinging gateway is now working but DNS resolution isn't.
ping google.com
ping: google.com: Temporary failure in name resolution
Tried setting name-servers manually using netplan but still no luck:
network:
version: 2
....
gateway4: 172.30.0.1
nameservers:
addresses: [172.30.0.1, 8.8.8.8]
Here are the contents of cat /proc/net/bonding/bond0
:
Bonding Mode: load balancing (round-robin)
MII Status: up
MII Polling Interval (ms): 0
Up Delay (ms): 0
Down Delay (ms): 0
Slave Interface: eth1
MII Status: up
Speed: 1000 Mbps
Duplex: full
Link Failure Count: 0
Permanent HW addr: 00:15:5d:ec:d3:08
Slave queue ID: 0
Update 2: Rebooting the machine fixed DNS
This is /etc/netplan/01-netcfg.yaml That I have set up on my DL380 for 4 link aggregation.

Required three fixes:
- Changed
bridges
tobonds
. - Added nameserver
- For true NIC teaming resiliency split the two NICs into separate interfaces for bond0
