dpid-mac-address
Species 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
signicant 16 bits (default to 0) and the DPID-MAC-ADDRESS, which is the least signicant 48 bits. OS10 currently
supports only one logical switch instance and the instance ID is automatically set to 0. This value is not
congurable.
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)#
Supported Releases 10.4.1 or later
in-band-mgmt
Congures 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 is not part
of the OpenFlow logical switch instance. All the ports are L2 ports by default. If you congure one of the front-
panel ports as the management interface, the port becomes an L3 port. You can congure an L3 IPv4 address only
to the front-panel port that you have specied in this command. Ensure that you have IP connectivity between the
specied port and the controller.
The no form of this command removes this conguration and the front-panel port becomes part of the OpenFlow
logical switch instance.
Example
OS10# configure terminal
OS10(config)# openflow
