3-12 Sun Fire B1600 Blade System Chassis Switch Administration Guide • June 2003
3.2.2 Setting the IP Address
By default, the switch searches for its IP address, default gateway, and netmask
using DHCP.
You can manually configure a specific IP address or direct the device to obtain an
address from a BOOTP or DHCP server. Valid IP addresses consist of four decimal
numbers, 0 to 255, separated by periods. Any other format will not be accepted by
the software.
Note – The IP address of the switch is in fact the IP address of the VLAN containing
the management port (NETMGT). By default, the management port is on VLAN 2.
Therefore, by assigning an IP address to VLAN 2 you set up network access to the
switch. Only the VLAN containing the management port should be assigned an IP
address. If you assign an IP address to any other VLAN, the original IP address is
immediately disabled and the new address takes immediate effect.
When setting the switch IP configuration using the web interface or CLI, the
following parameters are displayed or can be configured:
■ Current IP Address – The current address of the VLAN interface that is allowed
management access.
■ MAC Address
4
– The physical layer address for this switch.
■ Management VLAN – The VLAN through which you can manage the switch. By
default, the management port (NETMGT) is configured as a member of this
VLAN (that is, VLAN 2). However, if you change the Management VLAN, you
will lose management access to the switch unless the NETMGT port has already
been configured as a member of the new VLAN. If this occurs, you will have to
use the console interface to add the NETMGT port to the newly configured
Management VLAN. (See Section 4.3.12.8, “switchport allowed vlan” on
page -127.)
■ IP Address Mode – The method through which IP functionality is enabled. The
options are manual configuration (Static), Dynamic Host Configuration Protocol
(DHCP), or Boot Protocol (BOOTP). If DHCP/BOOTP is enabled, IP will not
function until a reply has been received from the server. Requests are broadcast
periodically by the switch for IP configuration settings. (DHCP/BOOTP values
can include the IP address, subnet mask, and default gateway.)
■ DHCP – Dynamic Host Configuration Protocol
Enable Client ID – Includes a client identifier in all communications with the
DHCP server.
