Why is there poor video performance and frame errors on the network with my 2161DS? - KB Article - 166183




Set the 2161DS network speed and duplex to match the network to which it is attached.

To configure the 2161DS Console Switch hardware network configuration, perform the following steps:

Access the Terminal menu.

  1. Connect a terminal or PC running terminal emulation software (such as HyperTerminal) to the configuration port on the back panel of the 2161DS Console Switch using the supplied serial cable. The terminal should be set to 9600 baud, 8 bits, 1 stop bit, no parity and no flow control. The terminal may be connected at any time, even when the unit is powered.
  2. Press any key to access the main menu.
    You will see the Terminal Applications menu with six options.
  1. Press the < 1 > key for the Network Configuration option. (Figure 1.)
    The network configuration menu will appear.

NOTE: Before making any changes work with the onsite network admin to determine the proper network configuration settings.

  1. Press the < 1 > key to select Network Speed. When possible, you should set your connection manually without relying on the auto negotiate feature. Once you enter your selection, you will be returned to the Network Configuration menu.
  2. Select option 2 and specify if you are using a static or BootP IP address. Dell recommends using a static IP address for ease of configuration. If you are using a BootP address, please configure your BootP server to provide an IP address to the 2161DS Console Switch, skip step 4 and continue to the next procedure.
  3. Select options 3-5 from the Terminal Applications menu, in turn, to finish configuring your 2161DS Console Switch for IP address, Netmask and Default Gateway.
  4. Once this is completed, type Ø to return to the main menu.

Video Optimization

To ensure optimal video quality you will want to configure the 2161DS Console Switch with the same settings as the network switch. For example, if the 2161DS Console Switch is set to Auto-Negotiate, then the network switch must be set to Auto-Negotiate both speed and duplex. If the 2161DS Console Switch is set to 100MB - full duplex, then the network switch must be set to 100MB - full duplex.

Once you have made these changes, you may need to refresh/flush the Address Resolution Protocol (ARP) tables in the network before you establish a new connection with the 2161DS Console Switch, especially if the 2161DS Console Switch has been in use within the hour preceding these changes.

To refresh the ARP table, do one of the following:

Wait approximately 10 minutes for the ARP tables to rebuild automatically.

-or-

Clear the ARP table entry in a video session viewer workstation and ping the appliance at its IP address. This can be done from a DOS window.

  1. Type ARP -d 1.2.3.4 (where 1.2.3.4 is the IP address of the 2161DS Console Switch).
  2. Type PING 1.2.3.4

If the PING is successful, the 2161DS Console Switch is ready for operation.
