Passwords can be up to 32 characters long.
Recovering from a lost password
By default, the CLI does not require passwords. However, if someone has
configured a password for the device but the password has been lost, you can
regain super-user access to the device using the following procedure.
Note: Recovery from a lost password requires direct access to the serial port and a
Complete the following steps to recover from a lost password:
1. Start a CLI session over the serial interface to the device.
2. Reboot the device.
3. While the system is booting, before the initial system prompt appears, enter b to
4. Enter no password at the prompt. (You cannot abbreviate this command.)
5. Enter boot system flash primary at the prompt. This command causes the

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, routers require an IP subnet address for the subnet in which you plan to
place them in your network.
The x-series devices support both classical IP network masks (Class A, B, and C
subnet masks, and so on) and Classless Interdomain Routing (CIDR) and network
prefix masks as follows:
v To enter a classical network mask, enter the mask in IP address format. For
v To enter a prefix number for a network mask, enter a forward slash ( / ) and the
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. Refer to the
