To configure the SHD:
From the SHD Configuration field, select
Configure SHD
.
The following SHD parameter fields appear:
Check Level
Transmit/Receive Error Threshold
Sampling Window Size
The default values of the SHD parameters are optimal for most networks. See
for explanations of the parameters.
11
When you have set all the configuration values, select
Save parameters and load
driver
.
The installation program loads the configured driver and then writes the
appropriate LOAD and BIND commands to the AUTOEXEC.NCF file. The system
assigns a network number.
12
Enter a network number, or press Enter to select the system-assigned number.
If no errors are encountered, the installation program asks whether you want to
select an additional network driver.
13
Continue with the installation:
If you are installing only one NIC, select
No
to finish loading and exit.
If you are installing more than one NIC, select
Yes
to set up another NIC.
Configuring Groups
Dynamic
Access
technology server features allow you to configure load balancing
groups. The load balancing features are described in
The following Dynamic
Access
technology server features are available for
NIC groups in NetWare:
■
Bidirectional load balancing
■
RSL failover
The examples in this section illustrate typical actions you might take in the course
of maintaining a Dynamic
Access
server configuration under NetWare. They show
how to add NICs and groups to a server where Dynamic
Access
technology server
features are already installed and configured.
Two drivers are associated with Dynamic
Access
technology server features in
NetWare: SE and LBRSL.
Planning the
Configuration
■
Plan the cable changes required to connect each primary NIC and all secondary
NICs to the same network segment.
■
For optimal failover performance, turn the spanning tree feature off at switches
that are connected directly to the server. If the spanning tree feature must be
turned on, a failover may be delayed up to 30 seconds while the switch
processes the spanning tree algorithm.
■
Decide which NICs are to be part of each group. Each group must
include at least two NICs.
