how does the bonding inteface get mac address on linux

~]# ifconfig | sed -n '/^*/p'īond0 Link encap:Ethernet HWaddr 00:19:00:00:00:FBĮth0 Link encap:Ethernet HWaddr 00:06:11:11:11:3BĮth1 Link encap:Ethernet HWaddr 00:19:00:00:00:FBĭoes any one know why I'm seeing this or how does it work? Thanks in advance. Now, according to the ifconfig, the MAC address allocation for eth0 and eth1 are different (from the above output) - they are switched. (I've replaced the middle bits of the MAC by 00 and 11 intentionally) In this tutorial, I will explain how to setup bonding under Debian Linux server to aggregate multiple Ethernet devices into a single link, to get higher data rates and link failover. ~]# cat /proc/net/bonding/bond0Įthernet Channel Bonding Driver: v3.4.0-1 (October 7, 2008) The issue is, if I connect 2 Debian systems with a bonding interface, then the 2 ends of the link has the same MAC address, and it all breaks. The Linux kernel comes with the bounding driver for aggregating multiple network interfaces into a single logical interface called bond0. Which is working fine and according to the /proc/net/bonding/bond0, the active-slave is eth1. brctl showmacs shows these entries but omits information about VLANs, therefore there are lines that look identical.

In effect FDB contains two entries per such interface: one entry with vlan X and one without. I've configured Channel-bonding (on RHEL/CentOS) with with balance-alb (mode=6) option:īONDING_OPTS='mode=balance-alb miimon=100 updelay=200 downdelay=200' Each bridged local interface has one VLAN filter entry added ( vlan X, most likely vlan 1 ).
