The switch configuration depends on whether you use factory default mode or Zero Touch Deployment.
With Zero Touch Deployment, the switch configuration consists of the following:
The ssh and sshd boot configuration flags are enabled by default.
All ports are Private VLAN isolated ports.
VLAN 4048 is created as an onboarding-vlan for host-only connectivity for In Band management. All front panel ports are members of VLAN 4048.
In Band management is enabled.
Dynamic Host Configuration Protocol (DHCP) client requests are cycled between In Band and Out of Band ports, except on the 5320 Series. 5320 Series supports In Band management only.
If the switch resets after the IP address is obtained from the DHCP Server, the entire DHCP process does not need to be repeated. Instead, the switch can directly send the DHCP Request to the DHCP Server for the IP stored in the /intflash/dhcp/dhclient.leases file.
Out of Band management is enabled, except on the 5320 Series. 5320 Series supports In Band management only.
All ports are administratively enabled.
IQAgent is enabled by default.
Zero Touch Provisioning Plus (ZTP+) for ExtremeCloud IQ ‑ Site Engine onboarding is enabled by default.
Initiates Zero Touch Fabric Configuration.
After the Zero Touch Fabric establishes successfully, the onboarding VLAN 4048 is automatically assigned to onboarding I-SID 15999999.
For information about IQAgent, see ExtremeCloud IQ Support.
The switch continues to support the boot configuration flag boot config flags factorydefaults to return an existing switch to factory default configuration.
Note
Zero Touch Deployment does not run on a switch returned to factory default configuration in this manner.
For more information, see Boot Sequence.
