Hi All
First I run this:
allssh manage_ovs --bridge_name br0 --interfaces eth0,eth1 --bond_name bond0 update_uplinks

and the expectation I would have Bond0 entry somewhere, however

I run the "ovs-appctl bond/show /bond0" command and I get this answer:
FIPS mode initialized
Nutanix AHV
no such bond
ovs-appctl: ovs-vswitchd: server returned an error


What am I missing?

@Eric-The_Viking After creating the bond0, you should check again whether that bond interface was successfully created or not:

On CVM: manage_ovs show_uplinks

(This command will list all interfaces appended to bridges on AHV host)



Anyway, the command you executed was not correct. It should be as below:



ovs-appctl bond/show bond0
Hi hienie



Thanks for the information, the show uplinks gives me:

Bridge: br0

Bond: br0-up

bond_mode: balance-slb

interfaces: eth1 eth0

lacp: off

lacp-fallback: true

lacp_speed: off

Bridge: br1



The show Bond0 - I had mis-typed in the text above but not in the CLI and get this result:



$ ssh root@192.168.5.1 "ovs-appctl bond/show"

FIPS mode initialized

Nutanix AHV

---- br0-up ----

bond_mode: balance-slb

bond may use recirculation: no, Recirc-ID : -1

bond-hash-basis: 0

updelay: 0 ms

downdelay: 0 ms

next rebalance: 59340 ms

lacp_status: off

active slave mac: 24:6e:96:9d:68:48(eth0)

slave eth0: enabled

active slave

may_enable: true

hash 84: 50 kB load

hash 151: 31 kB load

hash 195: 8 kB load

hash 204: 6222 kB load

slave eth1: enabled

may_enable: true



So given what QuanTran has said is this actually correct ahowing br0-up? and bond0 will not show anything?



Thanks




As I remembered, bond0 was the default name of bond interface in NOS 4.x series.

From AOS 5.x, the default name has been changed to br0-up.

So, from your command output, I can have a conclusion that:

Your br0 bridge having br0-up bond interface running Load Balancing mode teamed by eth0 and eth1 physical interfaces.

If you want to check the configuration of your bond interface, just execute the below command as reference:

ovs-appctl bond/show [bond_interface_name]

It must be br0-up not bond0

from ahv
to know the status of bond
code:
ovs-appctl bond/show


Change bond-mode
code:
[Active-Backup]
ovs-vsctl set port bridge_name bond_mode=active-backup
[slb]
ovs-vsctl set port bridge_name bond_mode=active-slb
ovs-vsctl set port bridge_name other_config:bond-rebalanceinterval=60000
[lacp]
ovs-vsctl set port bridge_name lacp=active
ovs-vsctl set port bridge_name bond_mode=balance-tcp
ovs-vsctl set port bridge_name other_config:lacp-fallbackup=true


From CVM
to change uplink interface.

code:
$allssh manage_ovs --bridge_name bridge_name --bond_name bondname --interfaces eth2,eth3 update_uplinks


to know the status of uplink
code:
$allssh manage_ovs show_interfaces
$allssh manage_ovs show_uplinks

Hi QuanTran - I read somewhere that once the Bond was created it changed br0-up to bond0 - so why would there be a show bond command?

Thanks
