When Does an AT-9410GB Switch Need an IP Address?
One of your first tasks as you begin to build your network will be to
determine which of the switches in your network should be assigned
unique IP addresses. The following two subsections help to explain how
to go about making this decision.
AT-9410GB
Switch
Every AT-9410GB switch on your network that you want to manage
remotely using the Telnet application protocol, a web browser, or an
SNMP management program must have a unique IP address. You cannot
remotely manage an AT-9410GB switch if it does not have an IP address.
You use the address to identify the switch when you start a remote
management session.
If you decide to assign an AT-9410GB switch an IP address, you must also
assign it a subnet mask. (The switch uses the subnet mask to determine
which portion of an IP address represents the network address and
which the node address.)
You must also assign the switch a gateway address if there is a router
between the switch and the remote management workstation. This
gateway address is the IP address of the router through which the switch
and management station will communicate.
You do not need to assign an IP address, subnet mask, or gateway
address if you do not intend to manage an AT-9410GB switch remotely.
The switch will function fine without these values and you can still
configure all switch parameters through a local management session.
How Do You
Assign an IP
Address?
Once you have decided which, if any, switches on your network need an
IP address, you have to access the AT-S45 software on the switches and
assign the addresses. You can do this two different ways.
The first method is to assign the IP configuration information manually.
The procedure for this is explained in the next procedure. Initially
assigning an IP address to a switch can only be done through a local
management session.
The second method is by activating the DHCP service on the switch and
have the switch automatically download its IP configuration information
from a DHCP server on your network. This procedure is explained in
Activating the DHCP Service on page 34.
