Wrong OpenFlow negotiation between HP3800 and HP VAN Controller
Hello,
I don't understant why my switchs HP3800 and HP3500 negotiated with my HP VAN Controller by using OF 1.0 and not OF1. 3.
The screen capture "nego.png" show that all my HP switch have negotiated in version 1.0.
On the same capture, you can see that the swith being IP 130.223.23.105 negotiated correctly in 1.3.0 (this is not an HP switch).
The screen capture "instance.png" show the Openflow instance information for one of my HP switch HP3800 with IP adresse 130.223.23.101. As you can see, the configures OF version is 1.3, but the negotiated is 1.0.
Why ?
Here is the HP 3800 running config:
hostname "hpmax1" openflow controller-id 1 ip 130.223.23.100 controller-interface vlan 23 instance aggregate controller-id 1 software-flow-table 4 version 1.3 enable exit enable exit oobm ip address 130.223.38.8 255.255.252.0 ip default-gateway 130.223.36.1 exit vlan 1 name "DEFAULT_VLAN" no untagged 1-2,5-24 untagged 3-4,25-26 ip address dhcp-bootp exit vlan 20 name "sdn-client" untagged 5-22 no ip address exit vlan 23 name "sdn-cnt" untagged 1-2, 23-24 ip address 130.223.23.101 255.255.255.0 exit
As you can see the OF version is 1.3 and not 1.0.
An idea ?
