<p class=MsoNormal>Hello<br>
<br>
It's been a while since I configured a cisco switch myself. I'm wondering if
you can help me... I'm trying to use vlan networking<br>
<br>
I have installed two nodes and my eth0 in both nodes goes to a cisco 2960
switch, to ports 1 and 3<br>
<br>
I used this command to create the network:<o:p></o:p></p>
<pre>nova-manage network create --multi_host T --network_size 16 --num_networks 16 --bridge_interface eth0 --fixed_range_v4 <a
href="http://172.16.0.0/12" target="_blank">172.16.0.0/12</a> --label internal<br>
<br>
<o:p></o:p></pre><pre><o:p> </o:p></pre><pre><o:p> </o:p></pre><pre><o:p> </o:p></pre><pre><o:p> </o:p></pre>
<p class=MsoNormal style='margin-bottom:12.0pt'>Here's my setup<br>
<br>
server1<br>
nova (all)<br>
glance<br>
keystone<br>
horizon<br>
<br>
server2<br>
nova(compute, volume and network)<br>
<br>
The nodes show the vlan100 interface so I think so far the problem I'm having
relies on the switch... maybe i haven't configured it correctly....<br>
<br>
Here's an ifconfig: <a href="http://pastebin.com/A3Z3tJz2" target="_blank">http://pastebin.com/A3Z3tJz2</a><br>
<br>
On the switch, I created vlan100 with a command like:<br>
vlan 100 name cloud<br>
<br>
Then configured the ports with:<br>
interface range fastethernet 0/1-4<br>
switchport mode access vlan 100<br>
<br>
This didn't work, so i was told i needed to enable Trunk mode. So I did with:<br>
interface range fastethernet 0/1-4<br>
switchport mode trunk<br>
switchport trunk native vlan 100<br>
<br>
But somehow i think im doing something in the switch, so that's why I'm asking
you guys<br>
<br>
I hope you can help me...<br>
<br>
Regards<br>
<br>
