18 ATTO Technology Inc. FastFrame NIC Installation and Operation Manual
Configuring a Group’s Operational
Settings
A FastFrame aggregate group derives most of its
operational settings, such as Offloads and jumbo
packets, automatically, based on the settings of the
network adapters in the group. Therefore, in order for
a feature to be in effect for a group, that feature must
be set identically on each member adapter. For
example, to enable jumbo packets for a group, enable
Jumbo Packets (by selecting the same jumbo packet
size, such as 9014) on each adapter. Likewise, in
order to disable checksum offloads, checksum
offloads must be disabled for each adapter.
Note
For best results, configure the settings on
each individual member adapter before
creating the group containing those
adapters.
CAUTIONCAUTION
Having adapters with mismatched
configuration settings can lead to loss of
connectivity and/or network I/O errors. To
ensure proper operation, each of the
underlying adapters in a group must be
configured the same.
Note
Reconfiguring an aggregate group - adding
or removing a port, or making certain
changes to a member adapter’s operational
settings - will result in momentary loss of the
group’s network connection.
After reconfiguration of FastFrame
aggregate groups, it may be necessary to
reboot the system in order for changes to be
applied completely
Creating an Aggregate Group
1 Open the FastFrame Link Aggregation
Properties page for one of the FastFrame
adapters that is to be included in the new group
as shown in 4-6.
2 Select the option to Create a new group of ports
3 Enter a name for the group and click OK.
4 Select the type of link aggregation to use.
Currently only Static aggregation is supported.
5 Click OK.
Note
The Group will be given the MAC address of
the first adapter added to the group.
Note
As shown in 4-7, the group will appear in the
Network Connections list and operate
similarly to any other network connection.
