NETGEAR 8800 User Manual Table 8. Common Commands (Continued) Command show banner unconfigure switch {all} Description Displays the user-configured banner. 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. 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 Safe Defaults Setup Method on page 38). All ports are enabled in the factory default setting; you can choose to have all unconfigured ports disabled on reboot using the interactive questions. In addition, you can return to the safe defaults mode by issuing the following commands: • unconfigure switch all • configure safe-default-script Safe Defaults Setup Method After you connect to the console port of the switch, or after you issue the unconfigure switch all or configure safe-default-script CLI command, the system returns the following interactive script: This switch currently has all management methods enabled for convenience reasons. Please answer these questions about the security settings you would like to use. Telnet is enabled by default. Telnet is unencrypted and has been the target of security exploits in the past. Would you like to disable Telnet? [y/N]: SNMP access is enabled by default. SNMP uses no encryption, SNMPv3 can be 38 | Chapter 2. Getting Started
