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.
Management IP Address
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.
Subnet Mask
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 are directly reachable.
Default Gateway
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.
