Configuring Dhcp/Bootp Relay; Verifying The Dhcp/Bootp Relay Configuration - Extreme Networks ExtremeWare XOS Guide Manual

IP Unicast Routing
The example in Figure 32 is configured as follows:
create vlan Finance
create vlan Personnel
create vlan MyCompany
configure Finance protocol ip
configure Personnel protocol ip
configure Finance add port 1:*,3:*
configure Personnel add port 2:*,4:*
configure MyCompany add port all
configure Finance ipaddress 192.207.35.1
configure Personnel ipaddress 192.207.36.1
configure rip add vlan Finance
configure rip add vlan Personnel
enable ipforwarding
enable rip

Configuring DHCP/BOOTP Relay

After IP unicast routing has been configured, you can configure the switch to forward Dynamic Host
Configuration Protocol (DHCP) or BOOTP requests coming from clients on subnets being serviced by
the switch and going to hosts on different subnets. This feature can be used in various applications,
including DHCP services between Windows NT servers and clients running Windows 95. To configure
the relay function:
1 Configure VLANs and IP unicast routing.
2 Enable the DHCP or BOOTP relay function, using the following command:
enable bootprelay {vrid <vrid>}
3 Configure the addresses to which DHCP or BOOTP requests should be directed, using the following
command:
configure bootprelay add <ip_address> {vrid <vrid>}
To delete an entry, use the following command:
configure bootprelay delete [<ip_address> | all] {vrid <vrid>}

Verifying the DHCP/BOOTP Relay Configuration

To verify the DHCP/BOOTP relay configuration, use the following command:
show ipconfig
This command displays the configuration of the BOOTP relay service, and the addresses that are
currently configured.
