This setting is optional and can also be completely omitted.
A bonding device defaults to the MAC address of the first physical device which is used
for bonding. If you do not want this it is possible to specify a MAC address the bonding
device should use here.
BONDING_DEV_x_MIIMON Default: BONDING_DEV_x_MIIMON=’100’
This setting is optional and can also be completely omitted.
Specifies the interval (in milliseconds) in which the individual connections of a bonding
device are checked for their link status. The link status of each physical device in the
bond will be checked every x milliseconds. Setting this to ’0’ will disable the miimon
monitoring.
BONDING_DEV_x_USE_CARRIER Default: BONDING_DEV_x_USE_CARRIER=’yes’
This setting is optional and can also be completely omitted.
If the link status check by miimon (see above) is enabled this setting can specify the
function performing the check.
• ’yes’: netif _carrier_ok() function
• ’no: direct calls to MII or ethtool ioctl() System calls
The netif_carrier_ok() method is more efficient, but not all drivers do support this
method.
BONDING_DEV_x_UPDELAY Default: BONDING_DEV_x_UPDELAY=’0’
This setting is optional and can also be completely omitted.
The value of this setting multiplied by the setting of BONDING_DEV_x_MIIMON specifies the
time a in which a connection of bonding devices is activated after the corresponding link
(for example ’eth0’) is up. This way the connection of the bonding device is activated
until the link status switches to "not connected".
BONDING_DEV_x_DOWNDELAY Default: BONDING_DEV_x_DOWNDELAY=’0’
This setting is optional and can also be completely omitted.
The value of this setting multiplied by the setting of BONDING_DEV_x_MIIMON specifies the
time a in which a connection of bonding devices is deactivated if the appropriate link (iE
an eth-device) fails. This will deactivate the connection of a bonding device temporarily
until the link status is back to ’active’.
BONDING_DEV_x_LACP_RATE Default: BONDING_DEV_x_LACP_RATE=’slow’
This setting is optional and can also be completely omitted.
Specifiy how often link informations are exchanged between the link partners (for example
a switch or another linux PC) if BONDING_DEV_x_MODE=” is set to ’802.3ad’.
• ’slow’: every 30 seconds
• ’fast’: each second.
