Hi All - Some light reading and softball questions for a Friday afternoon.
Here are some common files that the cisco mech driver (and I'm assuming the other mechanism drivers) will need to start off. common/exceptions.py common/constants.py We might even want to consider moving config.py into the common/ directory. In the Cisco (sub)plugin we have some specific DB requirements. I'm thinking we may want a db/ directory also. XML vendor specific strings. Store under common/snippets_"vendorname".py? How do we want to abbreviate mechanism driver files? md, mech_driver, mdriver, mech (contrasting to "type_xyz" drivers) Thanks, Rich From: Andre Pech [mailto:ap...@aristanetworks.com] Sent: Wednesday, June 19, 2013 12:24 PM To: OpenStack Development Mailing List Subject: Re: [openstack-dev] [networking][ml2] Device configuration I don't feel too strongly either way. It seems like mechanism drivers will have distinct sets of variables, so having a common subsection name may be confusing. Plus I like the clarity of the type of the mechanism driver being in the section name rather than hidden in a type name. Maybe we prepend ML2_MECH to that to make it clear that these are variables for mechanism drivers? Something like: [ML2_MECH_CISCO_NEXUS:<ipaddr> ... [ML2_MECH_ARISTA:<ipaddr>] ... As I said before, am fine with either of the proposals below too.

Cisco defines external devices in our INI file like this: # Nexus Switch Format. # [NEXUS_SWITCH:<IP address of switch>] # <hostname>=<port> <- for cisco nexus devices a port would be in the form "<slot>/<port#>" # ssh_port=<ssh port> # username=<credential username> <- used as login username to the switch # password=<credential password> <- password for that username Any thoughts on how we want to define this configuration info under ML2? The simplest solution is to have separate INI sections for each vendor/device. Ex. [CISCO_NEXUS:<ipaddr>] Variables defined only for cisco nexus devices [ARISTA_XYZ] Whatever you want. Note that the cisco INI file can define more than one NEXUS_SWITCH section (different IPs). We could think about creating more generic section headers but would need a variable telling us what device owns that section. Ex. [ML2_MECH_DEVICE:<ip_addr>] variable1 = variable2 = type = cisco_nexus The cisco config.py file doesn't have default values for these sections. At init time we create a dictionary of these devices. Thoughts?
