This object configures the behavior of DHCP
snooping when forwarding a DHCP packet from
an untrusted port that already has a DHCP
relay information option present. The
policies supported are:
keep - forward the packet without
updating the existing option
replace - replace the existing option
with one generated by this switch
drop - drop the packet
This policy is only applied if DHCP snooping is
enabled and hpicfDhcpSnoopOpt82Insert is true.
In all cases where this policy is applied, if
there is no relay information option present in
the received packet, DHCP snooping will add one.
The default policy is drop.
