Figure 1-2 BOOTP Relay Agent Configuration
The use of two servers provide failover redundancy. The client request is forwarded to both
BOOTP servers configured on the switch. However, no health checking is supported.
Configuring the BOOTP Relay Agent
To enable the GbE Switch Module to be the BOOTP forwarder, you need to configure the
BOOTP server IP addresses on the switch, and enable BOOTP relay on the interface(s) on
which the BOOTP requests are received.
Generally, you should configure the command on the switch IP interface that is closest to the
client, so that the BOOTP server knows from which IP subnet the newly allocated IP address
should come.
Use the following commands to configure the switch as a BOOTP relay agent:
>> # /cfg/l3/bootp
>> Bootstrap Protocol Relay# addr <IP address>(IP address of BOOTP server)
>> Bootstrap Protocol Relay# addr2 <IP address>(IP address of 2nd BOOTP server)
>> Bootstrap Protocol Relay# on
>> Bootstrap Protocol Relay# off
>> Bootstrap Protocol Relay# cur
Use the following command to enable the Relay functionality on an IP interface:
>> # /cfg/l3/if <interface number>/relay ena
