FNGi DHCPatriot Version 6, Руководство по эксплуатации

Страница: 61 / 104

Sometimes the relay agent that is
forwarding the DHCP packets to the
DHCPatriot may not be in the same
subnet as the dynamic subnet that
was specified previously. If this is the
case, what we call a maintenance
subnet may be specified. The
Maintenance Subnet area (figure 9.6)
under the DHCPv6 menu is provided
for this purpose. Simply choose the
Shared Network that the
Maintenance Subnet should belong
to. Type the maintenance subnet
and press commit.
From time to time, it may be
necessary to stop a certain IP
address from being allocated to a
client. This could be necessary due
to an address conflict, placement of
an administrative device in the
subnet that is normally all
dynamically assigned via DHCPv6,
or simply because you need a client
to vacate a certain IP address for
other purposes. The DHCPatriot
supports excluding an IP address
from being assigned dynamically.
Enter the Exclude IP Address area
(figure 9.7) under the DHCPv6 menu.
Type the address that you wish to
exclude. Add a note if desired and
press commit. This address will then
be excluded from dynamic
assignment.
New in version 6.1.0 is View Address
Usage for DHCPv6 (see Figure 9.8).
This works in a similar manner to
View Address Usage under DHCPv4.
There are a couple of differences,
however.
First, Available IPs and percentage of
IPs used for the IPv6 subnets are not
shown. These will typically be /64 in
