ip dhcp-relay include-secondary
Enables Dynamic Host Configuration Protocol (DHCP) Smart Relay, which can use secondary
addresses configured on a VLAN or VRRP interface.
Syntax
- default ip dhcp-relay
include-secondary
- ip dhcp-relay
include-secondary <parallel | sequential>
- no ip dhcp-relay include-secondary
Command Parameters
- parallel
- Specifies smart functionality
of the DHCP relay. In parallel mode, the relay agent makes multiple copies
of DHCP requests and inserts each IP address of the client- facing interface
(VLAN or VRRP) as the gateway address in each copy of the request. The
switch simultaneously relays multiple packets to the DHCP server, assigning
each packet the correct IP address in the correct subnet
- sequential
- Specifies smart functionality
of the DHCP relay. In sequential mode, the relay agent forwards received
DHCP packets from all IP addresses on the VLAN or VRRP interface one at a
time, starting with the primary address and continuing with each secondary
address. Each time a packet is received, the agent selects an address on the
VLAN or VRRP interface. The relay agent forwards three client requests to
the DHCP Server before repeating the process and cycling through all of the
primary and secondary IP addresses.
Default
The default is disabled.
