Note
The DHCP Client is disabled by default on previously configured or upgraded switches.
The switch ships directly from manufacturing with Fabric Engine Release 8.6 or later.
The primary and secondary configuration file is not on the switch.
The primary and secondary configuration file fail to load on the switch.
The DHCP Client is not available if RMON2 is configured on a Management Instance, and RMON2 is not available if the DHCP Client is configured on a Management Instance.
When DHCP is enabled on a Management Instance interface, the DHCP Client initial broadcast discovery packet and initial response from the DHCP server are not counted or shown in KHI management statistics for the management interface. Only the packets after the DHCP IP address assignment completes are counted and shown. After an IP address is assigned, a UDP socket opens and packets are counted on the interface.
If you change the DHCP Client configuration between management VLAN, OOB, or cycle, the default route provided by the DHCP server might delete and add with a different nexthop or network. DHCP Client configuration changes can cause interruptions to existing management connections.
DHCP static routes are not saved in the configuration file or displayed in show running-config. You can view DHCP static routes with show mgmt ip route static. If the DHCP Client adds a default route to an interface, the previous default route is deleted. If you modify a default route created by the DHCP Client, the route type output of show mgmt ip route static changes from DHCP to STATIC. You can save the modified to static default route to the configuration file, but on reboot the DHCP Client deletes the modified default route and restores the default static route the DHCP server specifies.
