System IP

[fatalXerror]

Hi Guys, I am new in SDWAN environment and I noticed that when I do a "show control connection" in my vManage or vSmart controllers, I cannot see the system IP address of the vBond, either it indicates 0.0.0.0 or blank in the show control connection output.

It that normal?

Thank you.

@fatalXerror : Whenever you setup is connected, it will only the connection between the vSmart, vManage and vEdges/cEdges. vBond only comes into initial authentication of the device. Once authenticated, no more connection to vBond.

Hi @inderdeeps , thanks for the feedback I really appreciated it.

Hi,

in general, in networking 0.0.0.0 means unknown.

Most probably the reason you see 0.0.0.0 or blank is you have connectivity problem between controllers and vbond.

Controller tries to connect vbond (initially it notes 0.0.0.0 as system ip) and then when it is unsuccessful it stops process (blank output) and restarts process.

try show control connections-history to understand the issue. I suggest using this doc. as well.

HTH,

Hi @Kanan Huseynli thanks for the feedback. However, I cannot find any logs for this particular scenario of mine and in fact, it is working fine, I can onboard vEdges to the SDWAN system but it is just strange that my vBond's system IP address and even the site-ID are showing 0.0.0.0 and 0, respectively when I do show control connections in my vManage.

Thank you very much for the help.

Hi,

I have checked on my lab. The same result for all instances (vCPU) expect the first one.

vManage# show control connections | inc vbond
0 vbond dtls 1.1.100.1 1.1.100.1 0
1 vbond dtls 0.0.0.0 - 0
2 vbond dtls 0.0.0.0 - 0
3 vbond dtls 0.0.0.0 - 0

The first instance shows true system IP of vbond. Others (1/2/3) shows 0.0.0.0

I have checked on another environment where vManage have 8 vCPU (i.e 8 instances). The same logic is implemented.

Site-ID is always zero (0) in CLI outputs.  Why I don't know (checked on 2 environment, the same result). I though may be vbond doesn't use this value in communication (like attribute), but it is seen in vManage GUI (Monitor->Network).
