HP Advanced Services zl Module with Microsoft® Windows Server® 2008 R2 Planning and Design Guide

Solution 3: Survivable Communications
Solution Implementation
Switch Clock
Note that the switch must be configured to the correct time. Its modules take
their time from the switch clock. If that clock is not accurate, the services
might fail; for example, the server cannot join the domain. Therefore, it is
recommended that the HP zl switch use SNTP to synchronize its clock to the
same server used by the domain controller.
Example Configuration
The configuration below indicates the time, VLAN, IP, and basic QoS config-
uration on the HP zl switch in this example solution. Your switch might be
configured with other features as well. In this example:
The switch connects to a WAN router on port A1.
The switch connects to Lync phones and computers on ports A2-A24 and
B1-B24.
The Advanced Services zl Module with Microsoft Windows Server 2008
R2 is installed in slot E.
The SBM is installed in slots D and F (referenced as slot F).
Note The configuration includes the VLAN assignment for the HP Services zl
Modules’ internal ports. However, you will not be able to configure these
assignments until you install the modules.
Also note that in a real world environment, the branch office would include
other switches with similar settings for edge ports.
