    • hostname (e.g., CS-Department)
    • enable secret (e.g., cisco12345)
    • line console 0 and line vty 0 4 with password and login configuration
    • security passwords minimum length 10
    • service-password encryption
    • username netadmin secret Cisco_CCNA7
    • ip domain-name cisco.com and crypto key generate rsa with 1024-bit encryption key strength
    • ip ssh version 2 and line vty 0 4 with login local and transport input ssh

Configuring Gigabit Ethernet Interfaces

  • Configure two Gigabit Ethernet interfaces using IPv4 and IPv6 addressing values.
  • Reconfigure link local addresses according to the Addressing Table.
  • Document interfaces in the configuration file using:
    • interface g0/0 and interface g0/1 with IP and IPv6 addresses, subnet masks, and descriptions.

Configuring the LAB 214-A Switch

  • Configure Vlan 1 as the SVI.
