BLADEOS 6.5.2 Application Guide

Establishing a Connection

The factory default settings permit initial switch administration through only the built-in serial port. All other forms of access require additional switch configuration before they can be used.

Remote access using the network requires the accessing terminal to have a valid, routable connection to the switch interface. The client IP address may be configured manually, or an IPv4 address can be provided automatically through the switch using a service such as DHCP or BOOTP relay (see “BOOTP/DHCP Client IP Address Services” on page 36), or an IPv6 address can be obtained using IPv6 stateless address configuration.

Note – Throughout this manual, IP address is used in places where either an IPv4 or IPv6 address is allowed. IPv4 addresses are entered in dotted-decimal notation (for example, 10.10.10.1), while IPv6 addresses are entered in hexadecimal notation (for example, 2001:db8:85a3::8a2e:370:7334). In places where only one type of address is allowed, IPv4 address or IPv6 address is specified.

Using the Switch Management Ports

To manage the switch through the management ports, you must configure an IP interface for each management interface. Configure the following IPv4 parameters:

￿IP address/mask

￿Default gateway address

1.Log on to the switch.

2.Enter Global Configuration mode.
