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 most significant 16 bits (default to 0) and the DPID-MAC-ADDRESS, which is the
least significant 48 bits. OS10 currently supports only one logical switch instance and the instance ID is
automatically set to 0. This value is not configurable.
You can use this command to modify the MAC address bits of the DPID.
Example
DPID MAC address is 00:00:00:00:00:0a.
OS10 (config)# openflow
OS10 (config-openflow)# switch of-switch-1
OS10 (config-openflow-switch)# dpid-mac-address 00:00:00:00:00:0a
OS10 (config-openflow-switch)#

Releases
10.4.1 or later
in-band-mgmt
To use one of the front-panel ports as the management interface that the SDN controller connects to.
Syntax
in-band-mgmt interface ethernet node/slot/port[:subport]
Parameters node/slot/port[:subport]—Enter the physical port information.
Default None
Command Mode OPENFLOW CONFIGURATION
Usage
Information
Use this command to convert any one of the front-panel ports as the management interface. This port
will not be part of the OpenFlow logical switch instance. All the ports are layer 2 ports by default. If you
configure one of the front-panel ports as the management interface, the port becomes an L3 port. You
can configure a layer 3 IPv4 address only to the front-panel port that you have specified in this command.
Ensure that you have IP connectivity between the specified port and the controller. Running the no form
of this command removes this configuration and the front-panel port becomes part of the OpenFlow
logical switch instance.
Example
OS10# configure terminal
OS10(config)# openflow
OS10 (config-openflow)# in-band-mgmt interface ethernet 1/1/1
OS10 (config-openflow)# no shutdown
