There are 4 traffic types in CloudStack - management, storage, guest and public. So, if you had four physical network interfaces, your bridging would be as below: eth0 -> cloudbr0 -> management eth1 -> cloudbr1 -> storage eth2 -> cloudbr2 -> guest eth3 -> cloudbr3 -> public If you had 8 physical interfaces: eth0+eth4 -> bond0 -> cloudbr0 -> management eth1+eth5 -> bond1 -> cloudbr1 -> storage eth2+eth6 -> bond2 -> cloudbr2 -> guest eth3+eth7 -> bond3 -> cloudbr3 -> public And if you had 12 interfaces: eth0+eth4+eth8 -> bond0 -> cloudbr0 -> management eth1+eth5+eth9 -> bond1 -> cloudbr1 -> storage eth2+eth6+eth10 -> bond2 -> cloudbr2 -> guest eth3+eth7+eth11 -> bond3 -> cloudbr3 -> public If you dont want to do bonding and had 3 NICs, then: eth0 -> cloudbr0 -> management eth1 -> cloudbr1 -> guest eth2 -> cloudbr2 -> public Next, if you had only 2 physical network interfaces, then... eth0 -> cloudbr0 -> management eth1 -> cloudbr1 -> guest+public Finally, if you had only ONE physical interface... eth0 -> cloudbr0 -> management+guest+public There is no bonding involved anywhere. Bonding is required only if you require to double your bandwidth requirements and/or build in fault tolerance (LAGG/LACP). > at this moment I have two bridges management(cloudbr1) and > public/guest(cloudbr0) in CS when I try to create a network under "Network > Offering" is blank and am unable to select anything. AFAIK, creating a new network offering via ‘Service Offering -> Network Offerings -> Add network offering’ is unrelated to your physical networking setup. > any idea? Bug in ACS maybe? Someone from the dev team might know more (or open a Jira ticket for the same). Also, you can always use the API to create network offerings. > > > On Mon, Jan 20, 2014 at 7:33 AM, Shanker Balan > <shanker.ba...@shapeblue.com>wrote: > >> Yeesh, wonder how steps (1) and (2) got deleted.
