Static IP via Option 82 - methodology

[perl-list]

Does anyone know if this statement is only relevant in the host declaration or is a global statement? Secondly, would this apply to host statements since the lease isn't recorded in the dhcpd.leases ? 

------------------------ 

The stash -agent-options statement 

stash -agent-options flag ; 

If the stash -agent-options parameter is true for a given client, the server will record the relay agent information options sent during the client's initial DHCPREQUEST message when the client was in the SELECTING state and behave as if those options 

are included in all subsequent DHCPREQUEST messages sent in the RENEWING state. This works around a problem with relay agent information options, which is that they usually not appear in DHCPREQUEST messages sent by the client in the RENEWING state, 

because such messages are unicast directly to the server and not sent through a relay agent.
