Hi I’m trying to setup network bonding active/backup
linked to two switches. Below are my configuration files: /etc/modprobe.conf alias bond0 bonding options bond0 mode=1 arp_interval=1000
arp_ip_target=192.168.000.161 primary=eth0 /etc/sysconfig/network-scripts/ifcfg-bond0 DEVICE=bond0 IPADDR=192.168.0.164 NETWORK=192.168.0.160 NETMASK=255.255.255.224 USERCTL=no BOOTPROTO=none > /etc/sysconfig/network-scripts/ifcfg-eth0 # Broadcom Corporation NetXtreme BCM5704 Gigabit Ethernet DEVICE=eth0 USERCTL=no > MASTER=bond0 SLAVE=yes BOOTPROTO=none ETHTOOL_OPTS="speed 100 duplex full autoneg off" ETH1 almost same configuration. Now some outputs: Ethernet Channel Bonding Driver: v3.0.3 (March 23, 2006) Bonding Mode: fault-tolerance (active-backup) Primary Slave: eth0 Currently Active Slave: eth0 MII Status: up MII Polling Interval (ms): 0 Up Delay (ms): 0 Down Delay (ms): 0 ARP Polling Interval (ms): 1000 ARP IP target/s (n.n.n.n form): 192.168.0.161 Slave Interface: eth0 MII Status: up Link Failure Count: 2 Permanent HW addr: 00:0d:60:14:a7:a6 Slave Interface: eth1 MII Status: up Link Failure Count: 11 Permanent HW addr: 00:0d:60:14:a7:a7 bond0 Link encap:Ethernet

Interrupt:193 Now here is my problem: When I physically disconnect eth0 everything works fine and all traffic flow via eth1 Second case eth0 has link up but not have
access to default gateway 192.168.0.161 (for example
access list or switch failure) eth0 goes down and eth1 which is ok try’s
to go up but w/o cusses. In the message log I can see only this: bonding: bond0: backup interface eth1 is
now down bonding: bond0: backup interface eth1 is
now up bonding: bond0: backup interface eth1 is
now down bonding: bond0: backup interface eth1 is
now up bonding: bond0: backup interface eth1 is
now down bonding: bond0: backup interface eth1 is
now up However exactly same setup works fine with REL
4.2 I suppose this can be a bug in FC5? |
