问题
We're getting errors and settings are not applied when using the following options for bonding:
Raw
BONDING_OPTS="mode=802.3ad downdelay=300 miimon=100"
Ordering them differently causes no issues:
Raw
BONDING_OPTS="mode=802.3ad miimon=100 downdelay=300"
决议
This behavior is expected as some options can only applied if others are already set. The init script just iterates through the given options. All options need to be specified in the proper order (e.g. "downdelay" can only be specified after enabling "miimon").
