I have a host using Linux bond mode 1 (active/backup) connected to 2 x independent switches. Please can someone confirm if this is possible for successful failover between NICS or do I have to interconnect the two switches? If this is already answered someplace please point me to the resource
Specification:- The 6.5 linux host is configured with the following ifconfig-bond1 files:-
[Server1 network-scripts]$ cat ifcfg-bond1
DEVICE=bond1
ONBOOT=yes
USERCTL=no
IPV6INIT=no
PEERDNS=yes
DHCP_HOSTNAME=Server1
BOOTPROTO=none
IPADDR=192.168.49.11
NETMASK=255.255.255.0
GATEWAY=192.168.49.254
BONDING_OPTS="mode=1 miimon=100 downdelay=200 updelay=200"
and 1Gbe eth0/1 interface files work like this:-
[server1 network-scripts]$ cat ifcfg-eth0
DEVICE=eth0
ONBOOT=yes
TYPE=Ethernet
MASTER=bond1
SLAVE=yes
USERCTL=no
[Server1 network-scripts]$ cat ifcfg-eth1
DEVICE=eth1
ONBOOT=yes
TYPE=Ethernet
MASTER=bond1
SLAVE=yes
USERCTL=no
eth0 connects to a primay switch whilst eth1 connects to the backup switch (2 x independent Juniper EX3300 models)
thanks
