930 | To load multiple instances of the module, it is necessary to | ||
931 | specify a different name for each instance (the module loading system | ||
932 | requires that every loaded module, even multiple instances of the same | ||
933 | module, have a unique name). This is accomplished by supplying | ||
934 | multiple sets of bonding options in /etc/modprobe.conf, for example: | ||
935 | |||
936 | alias bond0 bonding | ||
937 | options bond0 -o bond0 mode=balance-rr miimon=100 | ||
938 | |||
939 | alias bond1 bonding | ||
940 | options bond1 -o bond1 mode=balance-alb miimon=50 | ||
941 | |||
942 | will load the bonding module two times. The first instance is | ||
943 | named "bond0" and creates the bond0 device in balance-rr mode with an | ||
944 | miimon of 100. The second instance is named "bond1" and creates the | ||
945 | bond1 device in balance-alb mode with an miimon of 50. | ||
946 | |||
947 | In some circumstances (typically with older distributions), | ||
948 | the above does not work, and the second bonding instance never sees | ||
949 | its options. In that case, the second options line can be substituted | ||
950 | as follows: | ||
951 | |||
952 | install bond1 /sbin/modprobe --ignore-install bonding -o bond1 \ | ||
953 | mode=balance-alb miimon=50 | ||
954 | 925 | ||
955 | This may be repeated any number of times, specifying a new and | ||
956 | unique name in place of bond1 for each subsequent instance. | ||
