Disabling the spanning tree PVST Interoperability mode

To disable the feature and run IEEE 802.1s MSTP, 802.1w RSTP, or 802.1d STP, use the following com-
mands at the CLI console prompt:
enable
configure
no spanning-tree mst mstp-rstp
spanning-tree mst configuration
instance 15 remove vlan 3-4093
Please note that you must configure the spanning tree mode, VLAN settings, port configuration, and other
relevant switch parameters to match the remaining requirements of the infrastructure.

Appendix C: Remote desktop considerations

Console display settings

Color depth as set in the RDC console is one of the biggest determinates of how much network bandwidth
a given end user consumes. For example, setting the color depth to 24-bit results in better looking graph-
ics at the expense of increased bandwidth consumption. For LANs and WANs, use 15-bit color, and
when using an analog modem, 256-color works best for optimal display, presentation, and network per-
formance.

Streaming video

Since RDC presents bitmapped screen images of the blade PC, streaming video is one of the most
demanding tasks for the entire CCI system. Though streaming video certainly functions using the CCI
architecture, it is best performed using through a high-speed connection (not a dial-up modem) for individ-
ual on-demand streaming video support. However, HP recommends that CCI end users use their local
access device's media player for streaming video. The use of the local browser or media player on the
access device is much more practical and a necessity for supporting multicast streaming video.

Network printing

The CCI environment accommodates network printing in the same manner as does any personal com-
puter using Microsoft Windows XP Professional. However, your environment may require additional
design considerations. Traditionally, distributed print servers are accessed on the local area network, and
bandwidth is consumed on the local level. In the case of CCI, all print traffic is transmitted from the PC
blade to the print server. Therefore, you must consider the bandwidth consumption of printing tasks in the
design process. Tools are available to help you understand and mitigate the network impact of this
change.

Local printing

The CCI environment supports most local printers enabled by the administrator and appropriately con-
nected to the access device. On local printers connected to typical PCs, the print job moves directly from
the PC to the printer over a very short distance on a dedicated connection. With CCI, a local print job
