Global BOOTP Relay Agent Configuration
To enable the G8124 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, you should 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 should
come.
In the G8124 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 provide failover redundancy. However, no
health checking is supported.
1. Use the following commands to configure global BOOTP relay servers:
2. Enable BOOTP relay on the appropriate IP interfaces.
BOOTP/DHCP Relay functionality may be assigned on a per-interface basis using the following
commands:
Domain-Specific BOOTP Relay Agent Configuration
Use the following commands to configure up to four domain-specific BOOTP relay agents for each
of up to 10 VLANs:
As with global relay agent servers, domain-specific BOOTP/DHCP functionality may be assigned
on a per-interface basis (see Step 2 in page 37).
