IP Unicast Routing
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 {vr <vrid>}
3 Configure the addresses to which DHCP or BOOTP requests should be directed, using the following
command:
configure bootprelay add <ip_address> {vr <vrid>}
To delete an entry, use the following command:
configure bootprelay delete [<ip_address> | all] {vr <vrid>}
Verifying the DHCP/BOOTP Relay Configuration
To verify the DHCP/BOOTP relay configuration, use the following command:
show bootprelay
This command displays the configuration of the BOOTP relay service and the addresses that are
currently configured.
UDP Echo Server
You can use UDP echo packets to measure the transit time for data between the transmitting and
receiving end.
To enable UDP echo server support, use the following command:
enable udp-echo-server {vr <vrid>}{udp-port <port>}
To disable UDP echo server support, use the following command:
disable udp-echo-server {vr <vrid>}
