  • Page 39: Local Console Management

    DES-5024 cannot be reached by any other means. Use Local Console Management to log into the DES-5024 for the first time. You do not need to know the IP address to log into the DES-5024 using Local Console Management.
  • Page 40: Telnet

    You can manage the DES-5024 via Telnet session. However, first you must assign a unique IP address to the DES-5024. Use Local Console Management to log into the DES- 5024 for the first time so that you can assign an IP address. Once you have assigned an IP address to the DES-5024, you can use the management method of your choice.

  • Page 53 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-5024 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.
