30 CHAPTER 4: CONFIGURING THE SWITCH sticker on the base of the Switch. This sticker contains the MAC address and default IP address of the Switch. To detect its IP information using the automatic configuration process, the Switch goes through the following sequence of steps: 1 The Switch tries to configure itself with the default IP address 169.254.x.y, where x and y are converted from the last two bytes of its MAC address. For example, if the MAC address were 08004E000102, the IP address would be 169.254.1.2. This address is used if the Switch is operating in a standalone mode, or no other switches on the network have this IP address. The Switch also assigns the subnet mask 255.255.0.0 (default class B mask) to itself. 2 If this default IP address is already in use on the network, then the Switch detects this, and increments the last byte of the MAC address by one to generate its IP address. The IP address would therefore become 169.254.1.3. 3 The Switch repeats step 2 until an unused IP address is found. 3Com recommends using automatic IP configuration only for the initial setup. Once you gain access to the console, you should assign an IP address to the Switch (either by using DHCP or assigning a static IP address) to ensure successful communication between the Switch and other network devices. Setting the IP Address To set the IP address for the Switch: 1 On the menu, click IP Settings. The IP Settings page appears. Figure 11 IP Settings Page 2 Configure the Switch's IP settings. Available options are listed in Table 8.

sticker on the base of the Switch. This sticker contains
the MAC address and default IP address of the Switch.
To detect its IP information using the automatic config-
uration process, the Switch goes through the following
sequence of steps:
1
The Switch tries to configure itself with the default IP
address
169.254.x.y
, where
x
and
y
are converted
from the last two bytes of its MAC address.
For example, if the MAC address were
08004E000102
,
the IP address would be
169.254.1.2
. This address is
used if the Switch is operating in a standalone mode, or
no other switches on the network have this IP address.
The Switch also assigns the subnet mask 255.255.0.0
(default class B mask) to itself.
2
If this default IP address is already in use on the
network, then the Switch detects this, and increments
the last byte of the MAC address by one to generate its
IP address.
The IP address would therefore become
169.254.1.3
.
3
The Switch repeats step 2 until an unused IP address is
found.
3Com recommends using automatic IP configuration
only for the initial setup. Once you gain access to the
console, you should assign an IP address to the Switch
(either by using DHCP or assigning a static IP address) to
ensure successful communication between the Switch
and other network devices.
Setting the IP Address
To set the IP address for the Switch:
1
On the menu, click
IP Settings
. The IP Settings page
appears.
