TFTP Client
The TFTP client downloads configuration files and sends TFTP requests to the broadcast IP address
(255.255.255.255).
DNS Client
The DNS client resolves an IP address to a hostname and resolves a hostname to an IP address (reverse IP
address to hostname mapping).
BOOTP/DHCP Client
The DHCP and BOOTP clients handle predefined IP address configuration. The DHCPINFORM
message type is sent to request Auto Config boot options.
Stacking
The downloaded configuration file is not distributed across a stack. When an administrator saves
configuration, the config file is distributed across a stack.
