1. Use the following commands to configure global BOOTP relay servers:
2. Enable BOOTP relay on the appropriate IP interfaces.

During switch startup, if the switch fails to get the configuration file, a message can
be recorded in the SYSLOG server.
The G8264 supports requesting of a SYSLOG server IP address from the DHCP
server as described in RFC 2132, option 7. DHCP SYSLOG server request option is
enabled by default.
Manually configured SYSLOG server takes priority over DHCP SYSLOG server.
Up to two SYSLOG server addresses received from the DHCP server can be used.
The SYSLOG server can be learnt over a management port or a data port.
Use the RS G8264# show logging command to view the SYSLOG server
address.
DHCP SYSLOG server address option can be enabled/disabled using the following
command:
RS G8264(config)# [no] system dhcp syslog
To enable the G8264 to be a BOOTP (or DHCP) forwarder, enable the BOOTP relay
feature, configure up to four global BOOTP server IPv4 addresses on the switch,
and enable BOOTP relay on the interface(s) on which the client requests are
expected.
Generally, it is best to configure BOOTP for the switch IP interface that is closest to
the client, so that the BOOTP server knows from which IPv4 subnet the newly
allocated IPv4 address will come.
In the G8264 implementation, there are no primary or secondary BOOTP servers.
The client request is forwarded to all the global BOOTP servers configured on the
switch (if no domain‐specific servers are configured). The use of multiple servers
provides failover redundancy. However, no health checking is supported.
RS G8264(config)# ip bootp­relay enable
RS G8264(config)# ip bootp­relay server <1‐5> address <IPv4 address>
BOOTP/DHCP Relay functionality may be assigned on a per‐interface basis using
the following commands:
RS G8264(config)# interface ip <interface number>
RS G8264(config­ip­if)# relay
RS G8264(config­ip­if)# exit
