Layer 3 Routing Commands 1532
User Guidelines
Enable DHCP Relay using the ip helper enable command.
When in Virtual Router Configuration mode, this command operates within
the context of the virtual router instance. When in Global Configuration
mode, the command operates on the global router instance.
Virtual Router Configuration mode is only available on the N3000/N4000
switches.
Example
The following example defines a maximum hopcount of 6.
console(config)#bootpdhcprelay maxhopcount 6
bootpdhcprelay minwaittime
Use the bootpdhcprelay minwaittime command in Global Configuration
mode to configure the minimum wait time in seconds for BootP/DHCP Relay
on the system. When the BOOTP relay agent receives a BOOTREQUEST
message, it might use the seconds-sinceclient- began-booting field of the
request as a factor in deciding whether to relay the request or not. Use the no
form of the command to set the minimum wait time to the default value.

• integer — Minimum wait time for BootP/DHCP Relay on the system.
(Range: 0-100 seconds)
