SD-WAN

Hi!

We're having some troble getting Network Visualizer work with 3810 switches. We have this really simple setup; two hosts connected to the switch and a HP VAN controller using oobm.

When we try to deploy a capture session, we get the following error: "Deploy failed, reattempt in progress". According to the manual, we should wait till the switch to recovers, but we have already waited days without any improvement. We also tried the same setup with OpenvSwitch and mininet and both worked just fine, so I guess we have some configuration issues with our 3810, but can't pinpoint the exact mistakes...  

I've included relevant lines from the log file as well as our switch configuration.

Hi Juuso,

Network Visualizer will not work with the OOBM connection due to the underlying Service Insertion technology used to enable the solution.  Please create another VLAN, assign a single port to it, and use it instead of OOBM for management in your environment.

example:

vlan 350

untagged <port num>  (that connects to controller network with Visualizer)

ip address 20.0.0.102

controller-id 11 ip 20.0.0.11 controller-interface vlan 350

Hope that helps.  (SNMP is another component needed to make Visualizer work, but I suspect your configuration is correct there)

Best Regards,

-Scott

Excellent!

No wonder every single example I have seen, had vlan instead of OOBM :)

We also had Network Protector complaining that the switch does not support Service Insertion tunnels and changing the OOBM to vlan also fixed this issue. 

Thank you,
Juuso
