[openstack-dev] FW: how to configure cisco plugin in devstack environment

Hi Yuling -
Are you now using either an external nexus switch and/or the Nexus 1000 in your topology?
If not then I don't know why you would enable Q_PLUGIN=cisco in devstack's localrc.
But if you want to move forward regardless of available Cisco devices then you would have to follow the instructions listed in that web link below or you can add some additional information to the localrc file. Robert has put this info on a Cisco internal webpage so I'll cut/paste here. At some point (if he hasn't already) we should add this info to the devstack.org documentation.
=====================================================
Customization in localrc
In addition to existing DevStack variables, DevStack with Cisco plugin supports the following bash variables that can be defined in localrc.
declare -a Q_CISCO_PLUGIN_SUBPLUGINS
Supported values are:
(openvswitch)
(openvswitch nexus)
(n1kv)
(n1kv nexus)
Defines the subplugins that will be deployed with this DevStack. For example:
declare -a Q_CISCO_PLUGIN_SUBPLUGINS=(openvswitch nexus)
------------------------------------------------------
declare -A Q_CISCO_PLUGIN_SWITCH_INFO
The value has the following format:
({<switch_ip>=<username>:<password>:<ssh_port>[:<compute-host-name>:<nexus-port-connected-with>] })
Defines the nexus switch information used in the deployment. This is a bash associative array with nexus switch ip addresses as keys. Essentially, it defines the switch's access information, and the compute hosts that are connected to the switch. An example looks like
declare -A Q_CISCO_PLUGIN_SWITCH_INFO= ([1.1.1.1]=admin:mySecretPassword:22:compute1:1/1:compute2:1/2)
If Q_CISCO_PLUGIN_SWITCH_INFO is not defined in localrc, it assumes no switch is used in the deployment. In that case, if the nexus subplugin is deployed (as indicated by the Q_CISCO_PLUGIN_SUBPLUGINS array), a fake switch (with a fake driver) will be deployed.
**** - Note - since you're not using any cisco devices I wouldn't declare this variable and have the fake nexus driver configured.
======================================================
Thanks,
Rich

Hi Rich,
I was able to use Robert's file of lib/quantum_plugins/cisco to run cisco plugin in devstack environment. However, I'm not sure if everything was set up correctly in my environment. I thought this configuration using Q_plugin=cisco in localrc would set up exactly the same environment as what the instructions on the following attached link describes. However, I was not able to see the 'quantum_l2network' database at all. All I saw was database 'cisco_quantum'. Is there anything wrong in my set up? Should I see 'quantum_l2network' at all?

Thanks,
YuLing

B.T.W., I'm not planning to use a Nexus switch in my testing environment for now...just would like to use the fake driver to see how it goes...will plugin a real switch later:-)
Thanks very much,
YuLing

HI Yuling -
Actually if you change the localrc as described below you won't have to install configobj (I don't think).
So change the localrc first, unstack, stack. I don't think at that point you'll have the configobj issue.
Thanks,
Rich

Hi Yuling -
Here are instructions I found on installing configobj: http://www.voidspace.org.uk/python/articles/configobj.shtml
Also, you didn't get the latest (master) cisco quantum code.
In localrc please add/change:
OFFLINE=False
RECLONE=yes
Also, are you using a nexus hardware switch in your topology?
Thanks,
Rich

Thanks very much for the information... I just tried commenting out #QUANTUM_BRANCH=stable/grizzly. However, when I ran 'stack.sh' again, I still hit the same issue.
>From reading the log, I can see quantum was trying to pick up cisco plugin. However, it failed at importing configobj at cisco_configparser.py. Could this be PYTHONPATH issue? (However, I don't see any instructions for changing this environment variable)
When you mentioned that

Do I need to pick up this change as well? The only thing I picked up was Robert's file of lib/quantum_plugins/cisco...the rest running on my environment was devstack grizzly release...
Thanks,
YuLing
