Specifying Asynchronous Interface Extended BOOTP Requests
FC-247
Cisco IOS Configuration Fundamentals Configuration Guide, Release 12.1
Router A has the following configuration:
! Allow the router to forward broadcast portmapper requests
ip forward-protocol udp 111
! Provide the router with the IP address of the diskless sun
arp 172.30.2.5 0800.2002.ff5b arpa
interface ethernet 0
! Configure the router to act as a RARP server, using the Sun Server's IP
! address in the RARP response packet.
ip rarp-server 172.30.3.100
! Portmapper broadcasts from this interface are sent to the Sun Server.
ip helper-address 172.30.3.100
The Sun client and server’s IP addresses must use the same major network number because of a
limitation with the current SunOS rpc.bootparamd daemon.
In the following example, an access server is configured to act as a RARP server.
! Allow the access server to forward broadcast portmapper requests
ip forward-protocol udp 111
! Provide the access server with the IP address of the diskless sun
arp 172.30.2.5 0800.2002.ff5b arpa
interface ethernet 0
! Configure the access server to act as a RARP server, using the Sun Server's
! IP address in the RARP response packet.
ip rarp-server 172.30.3.100
! Portmapper broadcasts from this interface are sent to the Sun Server.
ip helper-address 172.30.3.100
Specifying Asynchronous Interface Extended BOOTP Requests
The Boot Protocol (BOOTP) server for asynchronous interfaces supports the extended BOOTP requests
specified in RFC 1084. The following command is useful in conjunction with using the auxiliary port as
an asynchronous interface.
To configure extended BOOTP requests for asynchronous interfaces, use the following command in
global configuration mode:
You can display the extended BOOTP requests by using the following command in EXEC mode:
Command Purpose
async-bootp tag [:hostname] data
Configures extended BOOTP requests for asynchronous interfaces.
Command Purpose
show async-bootp
Shows parameters for BOOTP requests.
