Chapter 3 Configuring the Switch
Initial Configuration
• SSH service on the switch (optional).
To enable this service, select the type of SSH key (dsa/rsa/rsa1) and number of SSH key bits (768
to 2048).
• NTP server IPv4 address (optional).
• SNMP community string (optional).
• Switch name (optional).
This is your switch prompt.
• An additional login account and password (optional).
Note If you are using IPv4, be sure to configure the IPv4 route, the IPv4 default network address, and the IPv4
default gateway address to enable SNMP access.
Default Login
The switch has the network administrator as a default user (admin). You cannot change the default user
at any time.
There is no default password so you must explicitly configure a strong password. If a password is trivial
(short, easy-to-decipher), your password configuration is rejected. Be sure to configure a strong
password. If you configure and subsequently forget this new password, you have the option to recover
this password.
Note If you enter a write erase command and reload the switch, you must reconfigure the default user (admin)
password using the setup procedure.
Configuring the Switch
This section describes how to initially configure the switch.
Note Press Ctrl-C at any prompt to skip the remaining configuration options and proceed with what you have
configured up to that point. Entering the new password for the administrator is a requirement and cannot
be skipped.
Tip If you do not want to answer a previously configured question, or if you want to skip answers to any
questions, press Enter. If a default answer is not available (for example, switch name), the switch uses
what was previously configured and skips to the next question.
To configure the switch for first time, follow these steps:
Step 1 Ensure that the switch is on. Switches in the Cisco Nexus 5000 Series boot automatically.
Step 2 Enter the new password for the administrator.
