Hello, you can specify more bondings options by selecting Bonding Mode "custom" and passing "miimon=100 updelay=0 downdelay=0 mode=802.3ad lacp_rate=1" there. Regards, Petr 2017-09-08 12:09 GMT+02:00 Gianluca Cecchi <gianluca.cecchi@gmail.com>:

Hello, when using CentOS as OS for hypervisor and mode=4 for bonding (802.3ad) in the past I had to use lacp_rate=1 (aka fast), because I noticed problems with the default lacp_rate=0 parameter. Now I'm testing an oVirt node and I see that into the graphical interface there are the options to set mode, link up and down delays, but not the lacp_rate option.

It is a different environment from the one where I had to modify it, so I will start with the default value and see if I get any problems again.

Now the ifcfg-bond0 file created at oVirt node level by the web mgmt interface contains:

BONDING_OPTS="miimon=100 updelay=0 downdelay=0 mode=802.3ad"

Would I be able to modify it in case of need and have it persistent across reboot, something like this:

BONDING_OPTS="miimon=100 updelay=0 downdelay=0 mode=802.3ad lacp_rate=1"

?

Thanks in advance, Gianluca
