Renaming switches in ODL

asked 2016-03-14 14:40:43 -0700

I currently have 3 Brocade switches setup as OF switches in ODL. The long string of numbers ODL assigns these switches isn't (from what I can tell) something I can retrieve from the actual switch using all the openflow commands I know (Brocade MLX's and ICX's), which means I need to load up Yang UI to get said arbitrary number... Is there any way to change the name ODL assigns a switch to something more memorable?

Hi,

I had a similar question. It may be useful to understand the controller negotiation process when a switch first connects:

OpenFlow enabled switches and controllers goes through a procedure called a Handshake. During this exchange of messages, the two parties gather information about one another, such as the Data-path ID to uniquely identify the switch, the maximum capacity of the buffer and how many bytes of a packet to send to the Controller

odl controller negotiation

Also,

I'm not sure about brocade switches, but apparently using openvswitch, you can set your datapath_id with the below command:

ovs-vsctl set bridge <mybr> other-config:datapath-id=<datapathid>

If you issue this command in openvswitch, you can also view the datapath-id:

 ovs-vsctl list bridge <mybr>

which gives you something like this:

_uuid               : 59e17067-5708-4829-8fca-9e5eee5134af
controller          : [80e4a4e5-2021-47f6-81fa-330a4f7fbbe1]
datapath_id         : "00006670e1592948"
datapath_type       : ""
external_ids        : {}
fail_mode           : []
flood_vlans         : []
flow_tables         : {}
ipfix               : []
mirrors             : []

Let me know if this helps.

Thanks for taking the time to answer my question SG! Very useful. Yea, it appears Brocade won't allow you to rename the datapath_id, at least from what I can see... So looks like I'm out of luck. Thanks again

So, is this not currently possible?
