How to Set Linux Bonding Interface to Gigabit
- by Kyle Brandt
I have enabled Linux active backup mode bonding. Each interface is a gigabit interface, but the bond interface seems to end up at 100 Megabit:
bonding: bond0: Warning: failed to get speed and duplex from eth1, assumed to be 100Mb/sec and Full.
...
bnx2: eth0 NIC Link is Up, 1000 Mbps full duplex, receive & transmit flow control ON
...
bonding: bond0: backup interface eth1 is now up
ethtool apparently can't provide info on bond:
sudo ethtool bond0
Settings for bond0:
No data available
So does this mean I am operating at 100 or 1000 Megabit (My guess is 1000)? If it is only 100, what options in the ifcfg scripts or the modprobe bonding options do I need to sett to make it 1000?
