Starting DynamicAccess Software

1 Log in to the Windows NT Administrator account.
2 From the Windows Start menu, select
Settings/Control Panel.
3 Double-click the DynamicAccess SW Server icon.
The Resilient Server Link/Load Balance/VLAN Configuration
window appears. It contains tabs for these windows:

Creating a Load Balancing/RSL and VLAN Configuration
Decide which NICs are to be part of each
Load Balancing/RSL group. Each group must
include at least two NICs.
Decide which NIC is to be the primary NIC in
each group.
Decide whether you want to specify failover to another
3C985B-SX server NIC or to a 3Com 3C980B-TX server
NIC. If you choose to failover to the 3C980B-TX server
NIC, you must disable load balancing for that group.
For optimum failover performance, turn the spanning
tree feature off at switches that are connected directly
to the server. If the spanning tree feature is turned on,
a failover may be delayed up to 30 seconds while the
switch processes the spanning tree algorithm.
Plan the cable changes required to connect each primary
NIC and all secondary NICs to the same network segment.
Observe the recommended support limits:
Four groups
I
64 VLANs per server

Assign a VLAN ID number to each VLAN. If you are not
using a DHCP server, each VLAN that is using IP services
requires an IP address and subnet mask.
In the Load Balance/RSL window, you can create and
change Load Balancing/RSL groups. The NICs in a group
work together to route traffic efficiently and to recover
from failures.
In the VLANs window, you can set up virtual LANs.
All groups listed on the Load Balance/RSL window also
appear as groups in the VLAN window. Any ungrouped
NICs in the Load Balance/RSL window are also listed in
the VLAN window.
