Usage Information
You can configure up to eight OpenFlow controllers.
If you specify the security tls option, the OpenFlow application looks for the following certificates and
private key in the following locations specified for certificate-based authentication. For information about
obtaining certificates and installing them on the switch and the controller, see Establish TLS connection between
the switch and the controller.
ca_cert
(certificate that
identifies the
controller as being
trustworthy)
/config/etc/opt/dell/os10/openflow/cacert.pem
certificate
(certificate that
identifies the
switch as being
trustworthy)
/config/etc/opt/dell/os10/openflow/sc-cert.pem
private key (the
private key
corresponding to
the switch
certificate)
/config/etc/opt/dell/os10/openflow/sc-privkey.pem
Example
The following example configures an OpenFlow controller with IP address 10.11.63.56 on port 6633 for the logical
switch instance, of-switch-1:
OS10# configure terminal
OS10 (config)# openflow
OS10 (config-openflow)# switch of-switch-1
OS10 (config-openflow-switch)# controller ipv4 10.11.63.56 port 6633
OS10 (config-openflow-switch)#
The following example configures multiple OpenFlow controllers on port 6633 for the logical switch instance, of-
switch-1:
OS10# configure terminal
OS10 (config)# openflow
OS10 (config-openflow)# switch of-switch-1
OS10 (config-openflow-switch)# controller ipv4 10.1.1.1 port 6633
OS10 (config-openflow-switch)# controller ipv4 10.1.1.8 port 6633
OS10 (config-openflow-switch)# controller ipv4 10.1.1.12 port 6633
OS10 (config-openflow-switch)# controller ipv4 10.1.2.17 port 6633
OS10 (config-openflow-switch)# controller ipv4 10.1.23.12 port 6633
OS10 (config-openflow-switch)# controller ipv4 10.1.99.121 port 6633
OS10 (config-openflow-switch)# controller ipv6 2025::1 port 6633
OS10 (config-openflow-switch)# controller ipv6 2025::12 port 6633
Supported
Releases
10.4.1.0 or later
dpid-mac-address
Specifies the MAC address bits of the datapath ID (DPID) of the logical switch instance.
Syntax
dpid-mac-address MAC-address
Parameters MAC-address—48-bit MAC address in hexadecimal notation, nn:nn:nn:nn:nn:nn
Default MAC address
Command Mode OPENFLOW SWITCH CONFIGURATION
Usage Information
The controller uses the DPID to identify the logical switch instance. The DPID is a 64-bit number that is sent to
the controller in the features_reply message. The DPID is constructed from the instance ID, which is the
