To support Zero Touch Deployment, a DHCP Client is used for the Segmented Management Instance VLAN management interface or Out-of-Band (OOB) management interface. The DHCP Client configuration supports a VLAN mode, OOB mode, and a cycle mode. DHCP Client cycle mode alternates IP address requests between the VLAN management interface and OOB management interface until an IP address is obtained on one of the interfaces. Priority is given to the OOB management interface.
You can also manually configure the DHCP Client to request an IPv4 address from a DHCP server for the In-band VLAN management interface, or the OOB management interface, or to cycle requests until an IP address is obtained on a VLAN or OOB management interface. The DHCP Client supports IPv4 addresses only, and cannot be enabled on multiple management interfaces simultaneously.
Note
If a default route is configured on an OOB or VLAN management interface, and then you configure DHCP so that it replaces the default route, the original default route is restored if you disable DHCP.
However, if the DHCP default route is updated or deleted after it is created by DHCP, the default route will not be replaced by the original route when DHCP is disabled.
