Re: [Xen-API] XCP: VLAN Issue

Here are the steps I just performed: http://pastebin.com/0zZAfHaf

I can now ping the address from another machine but cannot ssh to it or telnet to any open ports.

Yes, that is correct.

Rob,

If I understand you correctly I am to remove the ip address assigned to xenbr1 ie (eth1) which is associated with the following PIF:

uuid ( RO) : e602777f-b4e9-e231-7858-81189c47c434
device ( RO): eth1
currently-attached ( RO): true
VLAN ( RO): -1
network-uuid ( RO): df87728a-e4a7-a16e-9f8c-c4c4c26dc35f

Which is connected to the trunked port on the switch. 

And instead I am to assign that IP address to the following PIF:

uuid ( RO) : d14427c2-4940-0db1-7d96-f55434af319e
device ( RO): eth1
currently-attached ( RO): true
VLAN ( RO): 201
network-uuid ( RO): 85a9aba5-73ea-4008-0a28-395c96be30fd

Which will allow me to communicate to dom0 over that PIF (201) on the VLAN as well as allow me to assign VM's to that network. Since currently the ip address that is assigned to eth1 has no idea what vlan it belongs on.  So I would leave the real eth1 (-1) interface without an IP

Thank you for your time with this,

Ronny

Hi Ronny,

 

If you want an IP address in dom0 that is on a VLAN (is that what you want?), you need to configure the VLAN PIF, i.e. the PIF that has VLAN != -1, the one I mentioned in my previous email. The IP address will then be on the bridge associated with that VLAN PIF, which would have a name starting with “xapi”. The bridge xenbr1 is associate with eth1, which is a trunk port in your case, so traffic on a VLAN will not end up at xenbr1 (only untagged traffic will).

 

Does that make sense?

 

Cheers,

Rob

To be more specific I am having trouble connecting to xenbr1 by it's IP.  So you are saying that I need to remove that IP from xenbr1 and assign it to the PIF for VLAN 201 instead so that I may access dom0 again with the 150.156.201.35 IP address?

Thanks,

Ronny

Rob,

The interface does have an ip assigned 150.156.201.35

The only way I can get a response from it is to ping the static IP on the local machine. The VM's are using the interface on the created VLANS almost perfectly however they sometimes exhibit strange behaviour such as loss of connectivity when connecting to another machine crossing over a vlan.
