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

Solution 4: Survivable Authentication and Authorization

Solution Implementation

The following sections provide some basic guidelines for implementing this

solution as well as references to places where you can find more information.

You may need to adapt these guidelines to fit your particular network infra-

structure.

Predeployment Steps

By default, the server that runs on the module requests a DHCP address on its

internal interface 2. Network administrators can set the IP addresses manually

instead, or the DHCP server administrator can create a fixed DHCP reserva-

tion for the server. Generally, the first option is preferred. In this example, the

server has a static IP address at 172.16.90.30/24.

However, if you select the latter option (for the initial setup if nothing else),

the server administrator should create the reservation in advance. The admin-

istrator needs to know the MAC address on the module’s internal interface

2. This MAC address is one higher than the address listed on the label on

module’s underside.

Branch HP zl Switch

You can configure whatever features your environment requires on the HP zl

switch that hosts the Advanced Services zl Module. 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 E5406 zl switch (172.16.90.10/24)

hosts the module. It connects to a WAN router (172.16.90.1/24), which provides

routing and connects the branch to the data center.
