42.7 dhcp relay information trust-all
To configure all interfaces on a router as trusted sources of the Dynamic Host Configuration Protocol
(DHCP) relay agent information option, use the dhcp relay information trust-all command in global
configuration mode. To restore the interfaces to their default behavior, use the no form of the command.
Command Syntax
dhcp relay information trust-all
no dhcp relay information trust-all
Default
All interfaces on the switch are considered untrusted.
Command Mode
Global configuration
Usage
By default, if the gateway address is set to all zeros in the DHCP packet and the relay information option
is already present in the packet, the DHCP relay agent will discard the packet. If the dhcp relay
information trust-all command is configured globally, the DHCP relay agent will not discard the packet
even if the gateway address is set to all zeros. Instead, the received DHCPDISCOVER or
DHCPREQUEST messages will be forwarded to the addresses configured by the dhcp-server
command as in normal DHCP relay operation.
