Enter
boot system flash primary
at the prompt. This command causes the device to bypass the system
password check.

After the console prompt reappears, assign a new password.
Configuring IP Addresses
You must configure at least one IP address using the serial connection to the CLI before you can manage the
system using the other management interfaces. In addition, Foundry routers require an IP subnet address for the
subnet in which you plan to place them in your network.
Foundry devices support both classical IP network masks (Class A, B, and C subnet masks, and so on) and
Classless Interdomain Routing (CIDR) network prefix masks.
•
To enter a classical network mask, enter the mask in IP address format. For example, enter
“209.157.22.99 255.255.255.0” for an IP address with a Class-C subnet mask.
•
To enter a prefix number for a network mask, enter a forward slash ( / ) and the number of bits in the mask
immediately after the IP address. For example, enter “209.157.22.99/24” for an IP address that has a network
mask with 24 significant (“mask”) bits.
By default, the CLI displays network masks in classical IP address format (example: 255.255.255.0). You can
change the display to the prefix format. See the
Foundry FastIron X-Series Configuration Guide
or the
Foundry
Enterprise Configuration and Management Guide
.
NOTE:
If your network uses a BootStrap Protocol (BootP) server or a Dynamic Host Configuration Protocol
(DHCP) server, you can allow the Foundry device to obtain IP addresses for the hosts on the network.
Devices Running Layer 3 Software
Before attaching equipment to a Foundry Layer 3 Switch, you must assign an interface IP address to the subnet
on which the router will be located. You must use the serial connection to assign the first IP address. For
subsequent addresses, you also can use the CLI through Telnet or the Web management interface.
By default, you can configure up to 24 IP interfaces on each port, virtual interface, and loopback interface. You
can increase this amount to up to 64 IP subnet addresses per port by increasing the size of the subnet-per-
interface table. See the
Foundry FastIron X-Series Configuration Guide
or the
Foundry Switch and Router
Installation and Basic Configuration Guide
.
The following procedure shows how to add an IP address and mask to a router port.
1.
At the opening CLI prompt, enter
enable
.
FESX Router> enable
2.
Enter the following
command at the CLI Privileged EXEC level prompt, then press Enter. This command
erases the factory test configuration if still present:
FESX Router# erase startup-config
CAUTION:
Use the
erase startup-config
command only for new systems. If you enter this command on a
system you have already configured, the command erases the configuration. If you accidentally do erase the
configuration on a configured system, enter the
write memory
command to save the running configuration to
the startup-config file.
3.
Access the configuration level of the CLI by entering the following command:
FESX Router# configure terminal
Privileged EXEC Level
FESX Router(config)#
Global CONFIG Level
4.
Configure the IP addresses and mask addresses for the interfaces on the router.
FESX Router(config)# int e 2
