RackSwitch G8000: Application Guide
To enable the G8000 to be the BOOTP forwarder, you need to configure the
DHCP/BOOTP server IP addresses on the switch. Generally, it is best tomust
configure the switch IP interface on the client side to match the client's subnet, and
configure VLANs to separate client and server subnets. The DHCP server knows
from which IP subnet the newly allocated IP address will come.
In G8000 implementation, there is no need for primary or secondary servers. The
client request is forwarded to the BOOTP servers configured on the switch. The use
of two servers provide failover redundancy. However, no health checking is
supported.
Use the following commands to configure the switch as a DHCP relay agent:
RS G8000(config)# ip bootp-relay server 1 <IP address>
RS G8000(config)# ip bootp-relay server 2 <IP address>
RS G8000(config)# ip bootp-relay enable
RS G8000(config)# show ip bootp-relay
Additionally, DHCP Relay functionality can be assigned on a per interface basis.
Use the following commands to enable the Relay functionality:
RS G8000(config)# interface ip <Interface number>
RS G8000(config-ip-if)# relay
