Chapter 21 DHCP Commands
DESCRIPTION
Specifies a pre-defined DHCP option 82 profile that the
Switch applies to the specified port(s) in this VLAN. The
Switch adds the Circuit ID sub-option and/or Remote ID
sub-option specified in the profile to DHCP requests that it
relays to a DHCP server.
Specifies the source IP address that the Switch adds to
DHCP requests from clients in this VLAN before forwarding
them.
The source IP address helps DHCP clients obtain an
appropriate IP address when you configure multiple
routing domains on a VLAN.
Disables DHCP relay.
System name is not appended to option 82 information
field.
Sets the Switch to not apply a DHCP option 82 profile to the
specified port(s) in this VLAN.
Removes the source IP address setting and sets this field set
to 0.0.0.0. The Switch automatically sets the source IP
address of the DHCP requests to the IP address of the
interface on which the packet is received.
Disables the relay agent information option 82.
DESCRIPTION
The broadcast behavior of DHCP packets (within the
VLAN(s) on which DHCP relay is enabled) will not be
terminated by the Switch.
The Switch terminates the broadcast behavior of DHCP
packets within the VLAN(s) on which DHCP relay is
enabled.
DESCRIPTION
Displays global DHCP relay settings.
Enables DHCP relay for all broadcast domains on the
Switch.
Note: You have to disable dhcp relay before you
can enable dhcp smart-relay.
Disables global DHCP relay settings.
Sets the IP addresses of up to 3 DHCP servers.
Allows the Switch to add system name to agent
information.
System name is not appended to option 82 information
field for global dhcp settings.
