Configuring the switch
By default, the switch does not authenticate the console login user at an AUX interface. To increase
system security and enable remote management:
• Configure remote access services, for example, Telnet or SSH.
• Configure authentication on each user interface, including the AUX interfaces.
Configuring authentication on a user interface
You can configure authentication on a user interface to control access to the switch.
Table 10 describes the Telnet login authentication methods available for a VTY user interface.
Table 10 Telnet login authentication methods
Authentication method Feature Application scenarios
None
Easy to configure, allows any user to Telnet to
your switch, and lowest in security Lab environments and extremely
secure network environments
Password
Easy to configure, secure, and flat user
management Environments that do not need
granular privilege management
Username and password
Complex to configure, secure, and
hierarchical user management
Environments where multiple
operators cooperate to manage
the switch

Guide.
Connecting the switch to the network
Before you connect the switch to the network, verify that all its basic settings are correct.
Connecting your switch to the network through twisted pair
cables
You can connect the 10/100BASE-TX ports, 1000BASE-T ports, and 10GBASE-T ports on your switch to
the network. These ports use RJ-45 connectors and support MDI/MDI-X auto-sensing. Use category-6A
or category-7 twisted pair cables to connect 10GBASE-T ports and category-5 or above to connect other
ports. For more information about twisted pair cables, see "Appendix D Cables."
To connect a 10/100BASE-TX, a 1000BASE-T port, or a 10GBASE-T port to a peer device:
1. Connect one end of a twisted pair cable to the port.
2. Connect the other end of the twisted pair cable to the RJ-45 Ethernet port of the peer device.
3. Check the port LEDs for incorrect connection.
For more information about the LED status, see "
Appendix C LEDs ."
