    The interface and options are the same with Local Console and Telnet Management. The difference is the type of connection and the port that is used to manage the DES-5016. D-View is a proprietary SNMP management program. D-View is provided with the DES- 5016.

  • Page 41: Local Console Management

    DES-5016 cannot be reached by any other means. Use Local Console Management to log into the DES-5016 for the first time. You do not need to know the IP address to log into the DES-5016 using Local Console Management.

  • Page 42: Telnet

    You can manage the DES-5016 via Telnet session. However, first you must assign a unique IP address to the DES-5016. Use Local Console Management to log into the DES- 5016 for the first time so that you can assign an IP address. Once you have assigned an IP address to the DES-5016, you can use the management method of your choice.

  • Page 43: Log In

    The Log In panel, displayed in Figure 18, is the first panel you see when connecting to the DES-5016.

  • Page 55 1500 byte packets are delayed by 1200 microseconds in a Store and Forward device versus 60 microseconds in a Cut-Through device. Store and Forward requires more memory because the DES-5016 must store the packet before sending it out. Advantages of Cut-Through Cut-Through is faster because the packet is sent as soon as the first 128 bytes are received.
