Accessing the Switch for the First Time

When you take your switch from the box and set it up for the first time, you must connect to 
the console to access the switch. You are prompted with an interactive script that specifically 
asks if you want to disable Telnet and SNMP, so these will not be available on your switch at 
next reboot. This is called the safe defaults mode. 

After you connect to the console and log in to the switch, the screen displays several 
interactive questions that lead you through configuring the management access that you 
want. You disable SNMP, or Telnet access by using the interactive script (see

Resets all switch parameters (with the exception of 
defined user accounts, and date and time information) 
to the factory defaults. 

If you specify the keyword all, the switch erases the 
currently selected configuration image in flash memory 
and reboots. As a result, all parameters are reset to 
default settings.
