3-Administering the MaxNAS R8
Jumbo Frame Support Jumbo frame support is a feature which allows Ethernet hardware to send, receive or
transport Ethernet frames greater than the default 1518 bytes packet size (Also
referred to as MTU). The MaxNAS R8 supports jumbo frames of up to 9000 bytes.
Jumbo frames will only
function if all of your network
devices support the same
size packets, please verify
that all of your client devices,
hubs, switches and gateways
support this feature before
enabling it.
IP Sharing Mode The MaxNAS R8 has the ability to route IP trafc from LAN2 to LAN1 using IP for-
warding. When used in conjunction with DHCP services on LAN2, the MaxNAS R8
can act as a router between two subnets. Please note that the MaxNAS R8 is not
a security appliance and is not intended to be used as your network gateway/
router. This feature is provided as a means of adding functionality only
Link Aggregation The MaxNAS R8 supports IEEE 802.3ad link aggregation, which denes a method
for using multiple Ethernet interfaces in parallel to increase the link speed beyond
the limits of any single interface
and to add redundancy in case of
switch or router failure. There are
three operating modes supported
by the MaxNAS R8:
• Load Balancing: Ethernet trafc will be directed over both ports for maximum
throughput and reliability
• Failover: In this mode, the
MaxNAS R8 will activate
LAN2 should the link on
LAN1 be interrupted for any
reason. Choose this option
for maximum availability
• 802.3ad: This mode will link both ports to operate in tandem, increasing overall
throughput.
IP Address Conguration By default, the LAN 1 “WAN” port is congured to obtain an IP address from your
DHCP server. This IP will be displayed at the bottom of the WAN Conguration page.
To assign a static IP to the MaxNAS R8, click the “Static” tab on this page. Set the IP,
Subnet Mask, Gateway,
and DNS server.
The IP address, Netmask,
Gateway, and DNS Servers
are only required if DHCP is
disabled. Consult your network administrator for more information on these values as
they are unique to your network.
WARNING: Make sure all your client devices,
hubs, switches, and gateways can support Jumbo
frames of the proper size before enabling this
feature. Failure to do so may render the network
port of your MaxNAS R8 inaccessible!
!
IMPORTANT: 802.3ad link aggregation requires
the use of a link aggregation capable router.
Consult your switch documentation to assure
compatibility and conguration instructions.
!
Note: In order to enable Link Aggregation
the MaxNAS R8 must have a static IP.
Note: After changing its IP, the MaxNAS R8 will
reboot, when it comes back up you will need to
connect to the new IP in order to complete any
additional settings changes.
