Invoking the X-Loader and U-Boot CLIs
During the boot process, you can perform various configuration tasks by accessing the X-Loader and U-
Boot CLIs, such as running memory tests (X-Loader) and activating the backup image or recovering a
password (U-Boot).
You are first prompted to enter the X-Loader CLI by pressing ESC key when the following message
displays:
Hit any key to stop autoboot
If you do not press a key, the boot process continues and you are prompted to enter the U-Boot CLI by
pressing any key.
After performing any of the X-Loader or U-Boot tasks, the switch automatically reboots when you exit
the CLI. To continue with the boot process without entering either CLI, do not press ESC key.
Reconfiguring Default Settings
The I/O Aggregator provides zero-touch configuration with:
• default user name (
root
)
• password (
calvin
)
• VLAN (vlan1) and IP address for in-band management (
DHCP
)
• IP address for out-of-band (OOB) management (
DHCP
)
• read-only SNMP community name (
public
)
• broadcast storm control (
enabled in Standalone and VLT modes, and disabled in programmable-
mux mode
)
• IGMP multicast flooding (
enabled
)
• VLAN configuration (
in Standalone mode, all ports belong to all VLANs
)
You can change any of these default settings using the CLI. You can change many of the default settings
using the CMC interface as described in
Before You Start
Before you reconfigure default settings, ensure that:
• The aggregator booted successfully when it powered on.
• The console connection is established and the login prompt appears on the screen of a VT100
terminal or terminal equivalent.
