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

Solution 2: Survivable Wireless Networking
Solution Implementation
Because you are deploying the server running on the module as a read-only
domain controller (RODC), you must also ensure that the domain and forests
are set up correctly on the other domain controllers. Refer to Microsoft
guidelines.
Branch HP zl Switch
You can configure whatever features your environment requires on the HP zl
switch that hosts the Advanced Services zl Module and the E-MSM765 zl
Mobility Controller. The sections below provide guidelines for the specific
configurations required by this solution.
Software Version
The HP zl switch in which you install the modules that support this solution
requires software version K.14.65, K.15.03, or greater. Version K.15.03 or
greater is recommended because it supports seamless failover from an active
to a standby management module on E8200 zl Series switches.
VLAN and IP Addressing
In this example implementation, the branch HP E5406 zl switch routes local
traffic and supports these VLANs:
 VLAN 294 for network infrastructure devices and the server that is running
on the HP Advanced Services zl Module
 VLAN 2917 to which users are assigned by the RADIUS server (NPS)
Because the E5406 zl switch routes traffic, it requires an IP address on both
VLANs (10.29.4.2 on VLAN 294 and 10.29.17.1 on VLAN 2917). Because users
are assigned to a different VLAN from the module’s server, the E5406 zl switch
must list that server’s IP address as the helper address (10.29.4.30).
You must also establish the correct VLAN assignments for the internal inter-
faces on the modules included in this solution:
 The module running the Windows Server 2008 R2 (slot E):
• Internal interface 1—This interface is disabled by default and will
remain in the default VLAN.
• Internal interface 2—This interface is placed in VLAN 294 (untagged).
The IP address will be 10.29.4.30/24.
 E-MSM765zl Mobility Controller (slot C):
