Title: Message Title

John Duarte commented on FACT-1379   Re: Facter returns incorrect MAC address for bonded interfaces Validated on Centos 7 x86_64 using puppet-agent at sha 5745d95 containing facter at sha e74c0b5. The bound system MAC address of 76:4a:4a:bf:bf:06 on the bond0 interface as shown by the output of ip link show below is correctly returned by facter: [root@xdp6nl4aaol1n07 ~]## ip link show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: ens160: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT qlen 1000 link/ether 00:50:56:8f:22:29 brd ff:ff:ff:ff:ff:ff 3: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT link/ether 76:4a:4a:bf:bf:06 brd ff:ff:ff:ff:ff:ff 4: dummy0: <BROADCAST,NOARP,SLAVE,UP,LOWER_UP> mtu 1500 qdisc noqueue master bond0 state UNKNOWN mode DEFAULT link/ether 76:4a:4a:bf:bf:06 brd ff:ff:ff:ff:ff:ff Facter response showing correct MAC address [root@xdp6nl4aaol1n07 ~]# cat /opt/puppetlabs/puppet/VERSION 1.4.1.111.g5745d95 [root@xdp6nl4aaol1n07 ~]# facter networking.interfaces.bond0.mac 76:4a:4a:bf:bf:06 Validate MAC on bonded interface The following are reproduction steps for testing that facter returns the correctly bonded MAC address for a bonded interface. Configure bonded interface on Centos 7 Reference RHEL documentation Ensure the bonding kernel module is loaded modprobe --first-time bonding Create bond0 interface cat > /etc/sysconfig/network-scripts/ifcfg-bond0 <<EOF DEVICE=bond0 IPADDR=172.16.32.1 NETMASK=255.255.255.0 _ONBOOT_=yes BOOTPROTO=none USERCTL=no NM_CONTROLLED=no EOF Create dummy0 interface This creates a dummy interface whose master is defined as bond0 ip link add type dummy cat > /etc/sysconfig/network-scripts/ifcfg-dummy0 <<EOF DEVICE=dummy0 BOOTPROTO=none _ONBOOT_=yes MASTER=bond0 SLAVE=yes USERCTL=no NM_CONTROLLED=no EOF Create dummy1 interface This creates a dummy interface whose master is defined as bond0 ip link add type dummy cat > /etc/sysconfig/network-scripts/ifcfg-dummy1 <<EOF DEVICE=dummy1 BOOTPROTO=none _ONBOOT_=yes MASTER=bond0 SLAVE=yes USERCTL=no NM_CONTROLLED=no EOF Restart network interfaces service network restart Verify bond0 on system Verify composition of bond0 cat /proc/net/bonding/bond0 The bond0 interface should contain slave dummy0 and dummy1 interfaces with their own unique MAC addresses. Example: # cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011)   Bonding Mode: load balancing (round-robin) MII Status: up MII Polling Interval (ms): 0 Up Delay (ms): 0 Down Delay (ms): 0   Slave Interface: dummy0 MII Status: up Speed: Unknown Duplex: Unknown Link Failure Count: 0 Permanent HW addr: 76:4a:4a:bf:bf:06 Slave queue ID: 0   Slave Interface: dummy1 MII Status: up Speed: Unknown Duplex: Unknown Link Failure Count: 0 Permanent HW addr: 6e:8c:18:41:5e:ee Slave queue ID: 0 Verify that bonded interfaces all have the same MAC ip link show The bond0 as well as the dummy0 and dummy1 interfaces should all have the same MAC address. In the example below, you can see that all three interfaces are bound to the MAC address of 76:4a:4a:bf:bf:06 # ip link show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: ens160: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT qlen 1000 link/ether 00:50:56:8f:22:29 brd ff:ff:ff:ff:ff:ff 3: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT link/ether 76:4a:4a:bf:bf:06 brd ff:ff:ff:ff:ff:ff 4: dummy0: <BROADCAST,NOARP,SLAVE,UP,LOWER_UP> mtu 1500 qdisc noqueue master bond0 state UNKNOWN mode DEFAULT link/ether 76:4a:4a:bf:bf:06 brd ff:ff:ff:ff:ff:ff 5: dummy1: <BROADCAST,NOARP,SLAVE,UP,LOWER_UP> mtu 1500 qdisc noqueue master bond0 state UNKNOWN mode DEFAULT link/ether 76:4a:4a:bf:bf:06 brd ff:ff:ff:ff:ff:ff Validate facter Facter should respond with the proper bonded MAC address as shown above for the bond0 interface. # facter networking.interfaces.bond0.mac 76:4a:4a:bf:bf:06 Add Comment   This message was sent by Atlassian JIRA (v6.4.13#64028-sha1:b7939e9) -- You received this message because you are subscribed to the Google Groups "Puppet Bugs" group.
