FCX648SHPOE Switch# configure terminal
FCX624 Router(config)#
3. Enter the following command to set the super user password:
FCX648SHPOE Switch(config)# enable super-user-password <text>
Note: You must set the super user password before you can set other types of
passwords.
4. Enter the following commands to set the port configuration and read-only
passwords:
FCX648SHPOE Switch(config)# enable port-config-password <text>
FCX648SHPOE Switch(config)# enable read-only-password <text>
Note: If you forget your super user password, refer to “Recovering from a lost
password.”
Syntax: enable super-user-password | read-only-password |
port-config-password <text>
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
system reset.
Use the following procedure to recover from a lost password.
1. Start a CLI session over the serial interface to the y-series device.
2. Reboot the device.
3. While the system is booting, before the initial system prompt appears, enter b
to enter the boot monitor mode.
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
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.
y-series 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.
v 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.
v
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.
