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)#
Supported
Releases
10.4.1.0 or later
in-band-mgmt
Configures 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 configure one of the front-
panel ports as the management interface, the port becomes an L3 port. You can configure an L3 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.
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
Supported
Releases
10.4.1.0 or later
max-backoff
Configures the time interval, in seconds, that the logical switch instance waits after requesting a connection with the OpenFlow controller.
Syntax
max-backoff interval
Parameters interval—Enter the amount of time, in seconds, that the logical switch instance waits after it attempts to
establish a connection with the OpenFlow controller, from 1 to 65,535.
Default 8 seconds
Command Mode OPENFLOW SWITCH CONFIGURATION
Usage Information If the interval time lapses, the logical switch instance re-attempts to establish a connection with the OpenFlow
controller.
Example
OS10 (config)# openflow
1008 OpenFlow
