Startup configuration requirements

This section describes the fields that you must complete with either the IP Address

Configuration utility or the Serial Interface Configuration menu procedure.

Enter a management IP address for the system. You need this address to manage

all system services, such as HTTP, FTP, and SNMP. This address must be

accessible from one of the switch's private physical interfaces. Therefore, the

management IP address must map to the same network as one of the private

interfaces.

For example, if you plan to assign IP address 10.2.3.3 with subnet mask

255.255.0.0 to the private physical interface, then the management IP address

must reside in the 10.2 network.

Carefully record the management IP address. Later, during the Quick Start or

the Guided Configuration, you will be asked to supply IP addresses for the

physical interfaces.

The subnet mask defines how many bits of the IP address represent the network

the device is on and how many bits represent the host's ID on the network.

The device uses the subnet mask to determine which IP addresses are directly

reachable on the network and which ones must be routed through a gateway. A

sample IP address is 10.2.3.3 with a subnet mask of 255.255.0.0. This indicates

that all hosts with addresses 10.2.n.n, where n is any number 0 - 255, are directly

reachable.

The default gateway is where packets are routed onto the private or public

network if there is not a specific route in the routing table to the desired location.
