Setting Up an IP Interface for Management 3-3

Setting Up an	IP is a standard networking protocol used for communications among
IP Interface for	various networking devices. To access the system using TCP/IP or to manage
Management	the system using SNMP, you must set up IP for your system as described in
	this section.
General Setup	You must first define an interface, which includes assigning an IP address to
Process	that interface, and then ping your IP management station to ensure that the
	connection is alive.
	Assign an IP host address to every port for system management.

Then you can finalize your IP setup by ensuring that the configurations of the following are correct for your network and changing them as necessary:

■Routes (See page 3-7)

■Address Resolution Protocol (ARP) cache (See page 3-11)

■Routing Information Protocol (RIP) (See page 3-12)

You can monitor IP activity for your system by displaying the IP statistics at any time.

Administering You define interfaces to establish the relationship between the ports on Interfaces your system and the subnets in your IP network. You can have up to 32

addresses on a single port and you can assign up to 17 ports per interface.

An IP interface has the following information associated with it:

■IP Address

This address is specific to your network. Choose it from the range of addresses assigned to your organization. This address defines both the number of the network to which the interface is attached and the interface’s host number on that network.

■Subnet Mask

A subnet mask is a 32-bit number that uses the same format and representation as an IP address. The subnet mask determines which bits in the IP address are interpreted as the network number, which as the subnet number, and which as the host number. Each IP address bit corresponding to a 1 in the subnet mask is in the network/subnet part of the address. Each IP address bit corresponding to a 0 is in the host part of the IP address.
