Getting Started with the Contivity Extranet Switch 4500
4-2
Preparing for Configuration
To properly prepare for Installation and Configuration of the Contivity Extranet
Switch, you should have the following items available:
• A Management IP Address for the system. You need this address to
manage all system services, such as HTTP, FTP, and SNMP.
• An IP Address for the LAN port that is available on the system board.
• Any number of Public IP Addresses; e.g., one IP address for each Public
LAN Interface.
• A plan to distribute IP addresses to clients when connections are
requested; e.g., via a DHCP server or an internal client address pool (with
an address pool you will need a range of IP addresses).
• An Authentication database: If you are not using internal
authentication via the LDAP database, then make sure you have
either the external LDAP or the RADIUS server(s) IP Address and
password or Shared Secret (password).
• An external accounting server, such as RADIUS, with its IP Address and
Shared Secret.
• Client dial-in: Prepare the clients for the type of tunneling protocol they
will be using. The PPTP client application is available for Windows 95 on
the Nortel Networks CD, and it comes with Windows 98 and Windows
NT operating systems. Nortel Networks also provides the IPsec client on
the Nortel Networks CD.
• A complete network topology of the “environment” in which you are
testing the Switch, including the Switch, the default router address, and
any other IP addresses that you think might be required.
