Master Hub Setup and Management 45
Setting Up the Master Hub
This section describes how to set the hub console parameters for the vari-
ous management options it supports. Note that the hub can be managed in-
band or out-of-band, and either through the built-in console program, or us-
ing an SNMP-management program such as D-View.
TCP/IP Settings
The hub needs to have an IP address assigned to it so that the network man-
agement system or TELNET client can communicate with it over the
network. The TCP/IP Parameters Configuration Menu allows you to change
the settings for the two different interfaces used by the hub: the internal Fast
Ethernet interface used for in-band communication, and the SLIP interface
used through the diagnostic port for out-of-band communication.
Note: if you need to set an IP address so that you can access the hub console
through a network, see the first section of this chapter.
Saved changes to any of the fields on this menu take effect the next time the
system is restarted. Fields that can be set include:
♦ Interface
. This parameter displays the type of interface the hub will use
for management communications.
♦ IP Address
. This parameter determines the IP address used by the
hub for receiving SNMP and TELNET messages. Should be of the
form xxx.xxx.xxx.xxx, where each xxx is a number (represented in
decimal) between 0 and 255. This address should be a unique address
on the network assigned to you by a network administrator. The same
IP address is shared by both the SLIP and Ethernet network interfaces.
♦ Subnet Mask
. This parameter sets the subnet mask that determines
the level of the subnet that the hub is on. Should be of the form
xxx.xxx.xxx.xxx, where each xxx is a number (represented in decimal)
between 0 and 255. If no subnetting is being done, the value should
