Setting Up the Hub
Setting Addresses
The hub management module uses the TCP/IP network environment for
downloading images and managing the hub.
Refer to the section “Downloading
New Images” later in this chapter for a discussion of downloading procedures.
The console command set provides for setting and displaying
TCP/IP-related addresses.
To display these addresses, enter the
show ip
command.
IP Address
The IP address is a unique 32-bit identifier for a specific TCP/IP host or other
device.
Contact your network administrator for the IP addresses that you need.
■
To set the IP address, type
set ip
followed by the hub’s IP address, the
netmask (optional), and the broadcast IP address (optional).
For example,
type:
set ip 128.45.87.25 255.255.0.0 128.45.255.255 [Enter]
Your input is echoed after you press [Enter], as shown below:
IP address
:128.45.87.25
Netmask
:255.255.0.0
Broadcast
:128.45.255.255
■
If you type only
set ip
, this usage message appears:
Usage: set ip address [netmask] [broadcast]
where address is the IP address for this hub
netmask is the IP network mask [optional]
broadcast is the IP broadcast address [optional]
e.g. set ip 128.45.87.25 255.255.0.0 0.0.255.255
■
If you type
set ip
followed by only one IP address, the netmask and
broadcast address are automatically calculated, as shown below:
set ip 128.45.87.25
IP address
:128.45.87.25
Netmask
:255.255.0.0
Broadcast
:128.45.255.255
