Why is bond mode 4 configured in /proc/net/bonding/bond1 when I have configured bond mode 1 in /etc/modprobe.conf on Red Hat Enterprise Linux 5?
Issue
- Why is mode=4 bonding shown in /proc/net/bonding/bond1 when I have configured mode=1 via /etc/modprobe.conf?
Environment
- Red Hat Enterprise Linux 5 (RHEL5)
- Observed on RHEL5.6 kernel-2.6.18-238.el5, but currently unknown if other versions are also affected.
-
2 or more bonding devices exist (eg. bond0 and bond1)
- Only minimal bonding information is configured in /etc/sysconfig/network-scripts/ifcfg-bondX:
$ cat etc/sysconfig/network-scripts/ifcfg-bond1 # Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection DEVICE=bond1 BOOTPROTO=none ONBOOT=yes USERCTL=no IPADDR=172.31.160.33 NETMASK=255.255.255.240- The bonding mode is configured via /etc/modprobe.conf:
$ grep bond etc/modprobe.conf alias bond0 bonding options bond0 miimon=100 mode=4 <-- bond0 is configurd mode=4 alias bond1 bonding options bond1 miimon=100 mode=1 primary=eth0 <-- bond1 is configured mode=1
