PicOS Boot File

The Pica8 PICOS software keeps its boot configuration in the picos_start.conf file located in the /etc/picos directory.

admin@LEAF-A$ ls /etc/picos/picos*
/etc/picos/picos_start.conf

User can use the more command at the Linux shell to display contents of the picos_start.conf file.

admin@LEAF-A$ more /etc/picos/picos_start.conf

The picos_start.conf boot file has the following four sections, each section having one or more variables:

PICOS
XORPLUS
OVS
ZTP

The following table describes the variables in picos_start.conf - the PicOS boot file.

Section	Variable	Value	Description

Section	Variable	Value	Description
PICOS	picos_start	xorplus	PICOS operates in the L2/L3 mode after the picos service is restarted, or the system is rebooted.
		ovs	PICOS operates in the OVS mode after the picos service is restarted, or the system is rebooted.
			The device boots into Linux as usual, but both the PICOS modes are inactive.
XORPLUS	xorplus_rtrmgr_verbose		Indicates that the xorplus_rtrmgr log is in use.
	xorplus_log_facility		Configures the logging facility.
	xorplus_finder_client_address		Configures IP address.
	xorplus_finder_server_address		Configures IP address.
OVS	ovs_database_file		Defines the Open vSwitch configuration database.
	ovs_inband_database_file		Defines the Open vSwitch inband configuration database.
	ovs_db_sock_file		Defines the Unix domain socket file for communication between ovsdb-server and ovs-vswitchd.
	ovs_switch_ip_address		Defines the Open vSwitch management IP address.
	ovs_switch_ip_netmask		Defines the subnet mask for the Open vSwitch management IP address.
	ovs_switch_gateway_ip		Defines the gateway for the Open vSwitch management IP address.
	ovs_switch_tcp_port		Defines the TCP port for communication between ovsdb_server and ovs-vswitchd.
	ovs_host_name		Defines the Open vSwitch host name.
	ovs_use_dhcp	true	Indicates that the Open vSwitch is getting its management IP address through DHCP.
	ovs_use_dhcp	false	Indicates that the Open vSwitch is configured with a static management IP address.
ZTP	ztp_disable	true	Indicates that ZTP (Zero Touch Provisioning) is disabled.
	ztp_disable	false	Indicates that ZTP (Zero Touch Provisioning) is enabled.
	otp_disable	true	Indicates that the OTP function is disabled.
	otp_disable	false	Indicates that the OTP function is enabled.
