Hi all, I just noticed that my two nics that are bonded via mode 0 are showing the same mac addy in ifconfig. Is this normal? In syslog I keep getting; kernel: pbond0: received packet with own address as source address Some guidance is appreciated before I dive in and troubleshoot. If I don't list the mac addy in my ifcfg-th# files, only one of the 2 nic comes up during boot. uname; 2.6.18-128.7.1.el5xen /etc/modprode.conf alias eth0 tg3 alias eth1 tg3 alias eth2 forcedeth alias eth3 forcedeth alias scsi_hostadapter2 mptsas alias scsi_hostadapter mptspi alias scsi_hostadapter1 mptfc alias scsi_hostadapter2 mptsas alias bond0 bonding options bond0 miimon=80 mode=0 alias peth0 tg3 /etc/sysconfig/network-scripts/ifcfg-eth0 # Broadcom Corporation NetXtreme BCM5715 Gigabit Ethernet DEVICE=eth0 BOOTPROTO=none USERCTL=no HWADDR=00:23:8B:CE:9C:5C ONBOOT=yes MASTER=bond0 SLAVE=yes TYPE=Ethernet /etc/sysconfig/network-scripts/ifcfg-eth1 # Broadcom Corporation NetXtreme BCM5715 Gigabit Ethernet DEVICE=eth1 BOOTPROTO=none USERCTL=no HWADDR=00:23:8B:CE:9C:5D ONBOOT=yes MASTER=bond0 SLAVE=yes TYPE=Ethernet /etc/sysconfig/network-scripts/ifcfg-bond0 DEVICE=bond0 IPADDR=10.0.70.11 NETMASK=255.255.0.0 NETWORK=10.0.0.0 BROADCAST=10.0.255.255 GATEWAY=10.0.10.1 ONBOOT=yes BOOTPROTO=none USERCTL=no TYPE=Ethernet ifconfig output; bond0 Link encap:Ethernet HWaddr 00:23:8B:CE:9C:5C inet addr:10.0.70.11 Bcast:10.0.255.255 Mask:255.255.0.0 inet6 addr: fe80::223:8bff:fece:9c5c/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:10714 errors:0 dropped:0 overruns:0 frame:0 TX packets:386 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1157674 (1.1 MiB) TX bytes:37307 (36.4 KiB) eth0 Link encap:Ethernet HWaddr 00:23:8B:CE:9C:5C UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:5618 errors:0 dropped:0 overruns:0 frame:0 TX packets:192 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:694966 (678.6 KiB) TX bytes:20541 (20.0 KiB) Interrupt:21 eth1 Link encap:Ethernet HWaddr 00:23:8B:CE:9C:5C UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:5570 errors:0 dropped:0 overruns:0 frame:0 TX packets:191 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:685771 (669.6 KiB) TX bytes:19584 (19.1 KiB) Interrupt:22 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:2111 errors:0 dropped:0 overruns:0 frame:0 TX packets:2111 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:5464730 (5.2 MiB) TX bytes:5464730 (5.2 MiB) pbond0 Link encap:Ethernet HWaddr 00:23:8B:CE:9C:5C inet6 addr: fe80::223:8bff:fece:9c5c/64 Scope:Link UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1 RX packets:11188 errors:0 dropped:0 overruns:0 frame:0 TX packets:383 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1380737 (1.3 MiB) TX bytes:40125 (39.1 KiB) virbr0 Link encap:Ethernet HWaddr 00:00:00:00:00:00 inet addr:192.168.122.1 Bcast:192.168.122.255 Mask: 255.255.255.0 inet6 addr: fe80::200:ff:fe00:0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:468 (468.0 b)
