  • Page 7 DES-3226L Layer 2 Fast Ethernet Switch User’s Guide The switch is also assigned a unique MAC address by the factory. This MAC address cannot be changed, and can be found by entering the “show switch” command into the command line interface, as shown below.
  • Page 8 DES-3226L Layer 2 Fast Ethernet Switch User’s Guide 1. Starting at the command line prompt DES-3226L:4# − enter the commands config ipif System ipaddress xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy. Where the x’s represent the IP address to be assigned to the IP interface named System and the y’s represent the corresponding subnet mask.
  • Page 9 DES-3226L Layer 2 Fast Ethernet Switch User’s Guide In the above example, the switch was assigned an IP address of 10.53.13.188 with a subnet mask of 255.0.0.0. The system message “Success” indicates that the command was executed successfully. The switch can now be configured and managed via Telnet and the CLI or via the Web-based management agent using the above IP address to connect to the switch.
