•
Have a service available—typically Dynamic Host Configuration Protocol (DHCP)—to
assign an IP address to the switch
• Configure a DHCP server on your network to meet your network requirements. You can
configure a J-EX Series switch to operate as a DHCP server. For more information, see
“Configuring DHCP Services (J-Web Procedure)” on page 447.
• Create one of the following configuration files, and store it on a TFTP server (or HTTP
server or FTP server) in the network:
•
A host-specific file with the name
hostname .conf
for each switch undergoing
autoinstallation. Replace
hostname
with the name of a switch. The
hostname .conf
file typically contains all the configuration information necessary for the switch with
this hostname.
• A default configuration file named switch.conf with the minimum configuration
necessary to enable you to telnet into the new switch for further configuration.
•
Physically attach the switch to the network using a Gigabit Ethernet port.
• If you configure the DHCP server to provide only the TFTP server hostname, add an IP
address-to-hostname mapping entry for the TFTP server to the DNS database file on
the Domain Name System (DNS) server in the network.
•
If the new switch is not on the same network segment as the DHCP server (or other
device providing IP address resolution), configure an existing device as an intermediate
device to receive TFTP and DNS requests and forward them to the TFTP server and
the DNS server. You must configure the LAN or serial interface on the intermediate
device with the IP addresses of the hosts providing TFTP and DNS services. Connect
this interface to the new switch.
• If you are using hostname .conf files for autoinstallation, you must also complete the
following tasks:
•
Configure the DHCP server to provide a
hostname .conf
filename to each new switch.
Each switch uses its
hostname .conf
filename to request a configuration file from the
TFTP server. Copy the necessary
hostname .conf
configuration files to the TFTP
server.
•
Create a default configuration file named
network.conf
, and copy it to the TFTP
server. This file contains IP-address-to-hostname mapping entries. If the DHCP
server does not send a
hostname .conf filename to a new switch, the switch uses
network.conf to resolve its hostname based on its IP address.
Alternatively, you can add the IP-address-to-hostname mapping entry for the new
switch to a DNS database file.
The switch uses the hostname to request a
hostname .conf
file from the TFTP server.
To configure autoinstallation:
1.
Specify the URL address of one or more servers from which to obtain configuration
files.
