As a user or administrator you can interact with your Cisco VXC clients through the embedded HTTPS web interface (the Administrative Web Interface) and On Screen Display (OSD). To minimize the total learning curve and maximize the accessibility, the web interface and OSD are organized as similarly as possible and are structured in a task-oriented fashion.
The Administrative Web Interface and the OSD let you configure the client through the GUI. With the
OSD, messages appear overlaid on the user display as required.
Note This document describes the interface for Cisco VXC Clients running PCoIP. This document does not describe the Administrative Web Interface for PCoIP software integrated into products such as VMware
View.
The configuration features are also available through some connection brokers and the Cisco VXC
Manager console (web-based tool used to manage multiple PCoIP endpoints). These features are not described in this guide. For more information on the Cisco VXC Manager, see the Administration Guide for Cisco VXC Manager .
This document has four main sections:
•
Administrative Web Interface Overview provides on overview of the Administrative Web Interface.
•
•
Working with the On Screen Display provides an introduction to the On Screen Display (OSD).
Cisco VXC PCoIP Configuration details the Cisco VXC client configuration using the PCoIP
Administrative Web Interface and the On Screen Display (OSD).
•
About the Overlay Pages discusses the user message overlay windows.
The Appendix contains:
•
•
Appendix B, “Client Language and Keyboard Support”
•
Appendix C, “Cisco VXC 2111/2211 Power Considerations”
This document is intended to give administrators and users a working understanding of a PCoIP system.

To access the Administrative Web Interface:
Procedure
Step 1
Step 2
Browse to the IP address of the client. The IP address used depends on how the IP addresses are determined within your IP network:
•
•
Static IP Address: the IP address is hard-coded and must be known
Dynamic IP Address: the IP address is dynamically assigned by the Dynamic Host Configuration
Protocol (DHCP) server and can be obtained from the DHCP server
Enter the IP address into the browser (for example, https://192.168.1.123).

When you choose 10 Mbps Full Duplex or 100 Mbps Full-Duplex and then click Apply, this warning message appears:
“Warning: When Auto-Negotiation is disabled on the PCoIP device, it must also be disabled on the switch. Additionally, the PCoIP device and switch must be configured to use the same speed and duplex parameters. Different parameters may result in a loss of network connectivity. Are you sure you want to continue?”
Click OK to change the parameter.
Note Always set the Ethernet Mode to Auto and use only 10 Mbps full-duplex or 100 Mbps full-duplex when the other network equipment (for example, switch) is also configured to operate at 10
Mbps full-duplex or 100 Mbps full-duplex. An improperly set
Ethernet Mode may result in the network operating at half-duplex
(which is not supported by the PCoIP protocol). The session will be severely degraded and eventually dropped.
Lets you configure the Maximum Transfer Unit packet size.
A smaller MTU may be needed for situations such as VPN tunneling because
PCoIP packets cannot be fragmented. Set the Maximum MTU Size to a value smaller than the network path MTU for the end-to-end connection between the virtual machine and client.
The Maximum MTU Size range is 500 to 1500 bytes.
Note The default MTU is 1300 for sessions with the remote virtual machine.

Kiosk mode is used with VXC clients when you want to provide access to Virtual Machines (VM) to multiple users in a public place (such as airports, bus stations, and stadiums). Such users use the zero client to obtain information that is not specific to any individual, such as bus schedules, sightseeing information, public phone numbers, and so on.
In addition, if there are concerns that a guest user might damage a VM by using it in an inappropriate way, you can configure the VM as non-persistent in the datacenter. In this case, the VM does not save any persistent information after it is powered down, and will restart in its original state when it is powered up again.
You can configure Kiosk Mode through the OSD or the Administrative Web Interface. Kiosk mode requires a properly configured VMware View environment. See VMware View documentation for more information.

Table 4-13 Bandwidth Parameters
Parameter
Device Bandwidth
Limit
Description
Defines the maximum bandwidth peak for the PCoIP system.
The bandwidth setting defines the bandwidth based on which side is sending data:
•
•
On the virtual machine side: from the virtual machine to the client (for example, graphics data)
On the client side: from the client to the virtual machine (for example,
USB data)
The usable range of the device bandwidth is 1000 to 220,000 kbps.
The PCoIP processor uses only the required bandwidth up to the Device
Bandwidth Limit maximum. The PCoIP processor dynamically adjusts the bandwidth in response to network congestion.
Setting the Device Bandwidth Limit to 0 configures the PCoIP processor to adjust the bandwidth depending on network congestion. If there is no congestion, there is no limit on bandwidth. That is, the processor uses the maximum rate available.
We recommend setting this field to the limit of the network connected to the client and virtual machine.
Note The setting in this field is applied immediately after you click Apply.
See Bandwidth and Image Configuration Example, page A-1 for an example
of setting the Device Bandwidth Limit.

Bandwidth Parameters (continued)
Parameter
Device Bandwidth
Target
Description
Defines the temporary limit on the network bandwidth during periods of congestion (packet loss). When the network experiences congestion, the device bandwidth is reduced rapidly to the target value and more slowly below this value. This allows for a more even distribution of bandwidth between users sharing a congested network link.
After the congestion is alleviated, the bandwidth used increases depending on the available network resources up to the Device Bandwidth Limit.
You must have a good understanding of the network topology before setting this to a non-zero value.
Lets you configure the bandwidth floor used by the firmware when congestion is present and when bandwidth is required. This lets you optimize performance for a network with understood congestion or packet loss. If the bandwidth is not required, the bandwidth used drops below the floor.
A setting of 0 lets the firmware reduce bandwidth to 1000 kbps for these network impairments. You must have a good understanding of the network topology before setting this to a non-zero value.
Note The firmware implements a Slow Start Algorithm that:
– Increases the bandwidth used until the bandwidth required is reached, network congestion is detected, or the Device Bandwidth
Limit is reached
–
–
Begins at the lesser of the Device Bandwidth Limit and 8000 kbps
Increases the bandwidth used within seconds
– Allows a graceful session startup for low bandwidth scenarios (for example, WAN)
After initiating a PCoIP session, users may temporarily notice low bandwidth video artifacts while the algorithm ramps up bandwidth use.
The RDP web page allows you to configure device parameters specific to the Remote Desktop Protocol
(RDP).
Note Cisco VXC PCoIP firmware is bundled with, and provides configuration options for, the RDP 5.2 client.
However, Cisco does not provide support for RDP network implementations with the
Cisco VXC 2111/2211 and recommends that you do not use the bundled RDP client.

Description
Lets you compromise between image quality and frame rate when network bandwidth is limited. Some use cases may require lower-quality images at a higher frame rate while others need higher-quality images at a lower frame rate.
In environments where the network bandwidth is constrained, moving the slider towards Reduced allows higher frame rates. Moving the slider towards
Perception-Free allows for higher image quality. When network bandwidth is not constrained, the PCoIP system maintains perception-free quality regardless of the Minimum Image Quality parameter.
Note The Minimum Image Quality must be less than or equal to the

Note The EDID override mode can be enabled only from the OSD.
Under normal operation, the GPU in the virtual machine queries the monitor to determine the monitor's capabilities. These are reported in the EDID information. In some situations, a monitor may be connected to a client in a way that prevents the client from reading the EDID information such as connecting through some KVM devices. In this case, configure the client to report default EDID information to the virtual machine by enabling the display override mode.
When this feature is enabled, the client provides EDID information to the user’s virtual machine display properties that indicates the following resolutions are supported:
•
•
•
800x600 @60 Hz
1280x800 @60 Hz
•
•
1280x960 @60 Hz
1280x1024 @60 Hz (native resolution advertised)

•
•
•
1680x1050 @60 Hz
1920x1080 @60 Hz
1920x1200 @60 Hz
Warning Enabling display override forces default-monitor display information that may not comply with the connected monitor and result in a blank monitor. Enable display override only when there is no valid
EDID information and when monitor display characteristics are understood.

Note Certain USB-powered devices require sufficient power to be available on the client to power them. If the client does not have sufficient power for a USB device, the USB device cannot function, regardless of the configurations on these screens.
The USB page lets you specify authorized and unauthorized USB devices. It is divided into two sections:
Authorized Devices (“white list”) and Unauthorized Devices (“black list”). Devices are authorized or unauthorized based on ID or Class. You can use wildcards (or specify “any”) to reduce the number of entries needed to define all devices.
See

for more details on USB configuration.
USB plug events are blocked in the Cisco VXC client hardware for unauthorized USB devices. The virtual machine cannot see or access the device for an additional layer of security.
The factory defaults for the client USB permissions are any, any, any (that is, authorized USB devices).
Note The USB permissions are updated only at the start of a PCoIP session. They are authorized in the following order of priority (highest to lowest):
1.
Unauthorized Vendor ID/Product ID

Display Position Map The display position map consists of four possible display positions. A maximum of two displays can be enabled at the same time.
Display Position When two displays are connected to the client DVI-1 and DVI-2 connectors the user must configure how the monitors are arranged. The Display Position settings support this. Using these settings the user can arrange the displays horizontally or vertically. For example, to arrange the displays horizontally with the monitor connected to DVI-1 on the left, set Display 0 Position and
Display 1 Position to Position 0 and 1, or Position 2 and 3, respectively. To arrange the displays horizontally with the monitor connected to DVI-2 on the left, set Display 0 Position and Display 1 Position to Position 1 and 0, or
Position 3 and 2, respectively.
Origin Origin is a read-only parameter that indicates the (x,y) position of the upper left-hand corner of a display.
Rotation You can configure the orientation of a display to:
• No rotation
Resolution
•
•
90° clockwise
180° rotation
• 90° counter-clockwise
The display resolution can be configured for a PCoIP session between a virtual machine and a client. The client detects the supported display resolutions of the monitor and populates them to the drop-down menu. By default, the native resolution of the display is used.

Overlay pages are a way of displaying pertinent information to users during a PCoIP session. These pages occasionally overlay the user’s remote session.
Status overlay pages show network, USB device, and monitor statuses as icons and text. The overlays have simple animation and appear when the status changes (that is, the network connection is lost or an unauthorized USB device is plugged in).
Loss of network connectivity is indicated using an overlay with the message “Network connection lost” over the most recent screen data. This overlay appears when the client network cable is disconnected or when no PCoIP protocol traffic is received by the client for more than 2 seconds.
Figure 5-1 Network Connection Lost Overlay
The lost network connection message appears until the network is restored or the timeout expires (and the PCoIP session ends).
Note It is not recommended to use this notification message when using PCoIP devices with virtual desktops.
Normal scheduling within the virtual desktop hypervisor can falsely trigger this message. For more

If the USB devices connected to the client cannot be handled by the USB ports, an overlay appears with the message “USB over current notice.” The overly appears until USB devices are removed to meet the current handling of the USB ports.
Figure 5-3 USB Over Current Notice Overlay
The overlay will be displayed until USB devices are removed to meet the current handling of the USB ports.
PCoIP technology is not compatible with half-duplex network connections. When a half-duplex connection is detected, an overlay appears with the message “Half-duplex network connection.”
Figure 5-4 Half-Duplex Overlay
Improper connection of the virtual machine video source is denoted by two possible overlays. These overlays appear for approximately five minutes. The monitor is put into sleep mode approximately 15 seconds later.
When no video source is connected to the virtual machine, an overlay appears with the message “No source signal.” This helps the user debug a situation where the virtual machine does not have video source connected or has stopped driving a video signal.
Figure 5-5 No Source Signal Overlay
Note This message can be triggered by the virtual machine going into display power save mode.
When a video source to on the virtual machine does not correspond to the video port used on the client, an overlay appears with the message “Source signal on other port.” This helps the user debug a problem where the video source is connected to the wrong port. You can correct this by swapping the video ports at the client.

This section provides detailed examples to help you determine how best to configure your own devices.
This example outlines the steps for optimizing user experiences in an environment where bandwidth is constrained. It is assumed that there are four task-based workers (web browsing, simple word processing, simple spreadsheet manipulation, and small video pages) that are to share one 100-Mbps switch.
Due to the nature of these tasks, the users do not require heavy graphics changes and each user likely requires peak network bandwidth at different times.
shows simplified bandwidth requirements for each user assuming they each had the full 100
Mbps available. The figure shows that network demand for each user peaks only for short periods (for example, when opening or closing pages, or scrolling a page).
Because the PCoIP system adapts quickly to available bandwidth, we recommend keeping the system defaults. However, the following examples show how to adapt the default settings if your configuration requires it.

Appendix A Usage Examples
Bandwidth and Image Configuration Example
Figure A-1 Simplified User Bandwidth Requirements (Assuming 100 Mbps)
In this example, the network is configured to minimize packet loss. Networks respond to congestion by dropping packets. The PCoIP processor responds to dropped (lost) packets by reducing the amount of bandwidth it generates. In most cases, the PCoIP processor conceals the packet loss to be imperceptible to the user. However, in some situations where bandwidth is low or network latency is high, it might be preferable to eliminate congestion-based packet loss by limiting the available bandwidth to each user.
In this example, we limit each user’s peak bandwidth to a hard limit of 25 Mbps (that is, the firmware does not use more than 25 Mbps).
We also set a target (soft limit) of 20 Mbps so that during periods of network congestion, the bandwidth is decreased rapidly to 20 Mbps and more slowly below 20 Mbps. This ensures that the available bandwidth is shared fairly if other network traffic further constrains the link.
To set the bandwidth limit to 25 Mbps:

This figure shows that all users are limited to 25 Mbps and do not have access to more bandwidth when required. It also shows that even when the usage is totaled, the total switch bandwidth (100 Mbps) is never fully used.
Also note that because there is no congestion, there is no requirement to reduce the bandwidth to the targeted 20 Mbps or lower.

Figure A-3 Simplified User Bandwidth Requirements (25 Mbps)
Appendix A Usage Examples
In the example where the client bandwidth was set to 25 Mbps, it is possible that users may occasionally require more than that bandwidth limit to fully render their display information at maximum quality and full frame rate. The PCoIP system gives two controls over imaging quality that can optimize the user experience in environments where bandwidth is constrained.
For users who prefer higher image quality than what the PCoIP protocol balanced-quality/frame-rate algorithm provides, increasing the client Minimum Image Quality setting may be beneficial.
The Maximum Initial Image Quality setting can change the peak bandwidth required by any user.
Decreasing the Maximum Initial Image Quality from the default setting of 90 can reduce the amount of bandwidth required per user while maintaining a minimum limit on the user experience.
Note This example uses the Administration Interface for configuring the client for Minimum Image Quality and Maximum Initial Image Quality. Although you can also use the OSD to configure the client, the
Maximum Initial Image Quality does not have a corresponding parameter in the OSD as it is meant as an administrator-only parameter due to the potential impact on network traffic.

Slide the Minimum Image Quality slider to the right.
Slide the Maximum Initial Image Quality slider to the left.
Click Apply to accept the changes.
Repeat for the other three user clients.
The Minimum Image Quality is now configured toward Perception-Free to increase the minimum image quality the system reduces to under any condition. This effect is only noticeable in limited bandwidth cases. If bandwidth is not constrained, the system always maintains perception-free quality. The
Minimum Image Quality feature does not alter the overall bandwidth requirements of the user.
The Maximum Initial Image Quality is now configured toward Reduced to limit the quality on the changed image (that is, initial video frame). A lower Maximum Initial Image Quality setting requires less bandwidth as the lower-quality initial image requires less bandwidth to create. In this case, the administrator and the users determined that setting the Maximum Initial Image Quality to 60 was a preferable way of reducing bandwidth requirements than setting a hard limit on the Device Bandwidth
Limit.
Regardless of the Maximum Initial Image Quality setting, the PCoIP system always builds unchanged regions of the display to a loss-less image
Note The Minimum Image Quality setting must always be less than or equal to the Maximum Initial Image
Quality setting.

Appendix A Usage Examples
Bandwidth and Image Configuration Example
This example shows the PCoIP protocol default bandwidth and imaging settings being used to take advantage of the usage characteristics of the group. (The characteristics in this example are similar to many actual usage groups.) Here the device bandwidth limit and device bandwidth target are configured to 0 (no limit) to allow more effective bandwidth sharing. The firmware alleviates bandwidth congestion by implementing a bandwidth adaptation algorithm that strives for fairness on shared networks. The firmware uses the bandwidth as determined by the Ethernet physical-layer device.
To configure the client bandwidth to no limit:
Procedure
Step 1
Step 2
Step 3
From a web browser, enter the IP address of the first user’s client.
Log in to the Administrative Web Interface for the client (using password if enabled).
From the Configuration menu, select the Bandwidth web page.
Figure A-5 Client Bandwidth Limit Configuration (0 Mbps, no limit)
Step 4
Step 5
Step 6
Step 7
Enter 0 in the Device Bandwidth Limited field to enable no limit.
Enter 0 in the Device Bandwidth Target field to enable no limit.
Click Apply to accept the changes.
Repeat for the other three user clients.
The bandwidth limit and target are now set to 0 Mbps (no limit) for each user. Due to the nature of the users’ tasks—light graphics changes and peak network demand at different times—little conflict is expected for the full 100-Mbps bandwidth. The users share the bandwidth more effectively and have fewer situations where their images would have to be compromised to meet a bandwidth limit.
When there is congestion, the firmware automatically reduces the bandwidth limit using a bandwidth adaptation algorithm that strives for fairness on shared networks. When the congestion clears, the firmware again opens the bandwidth limit.
This figure shows that the bandwidth is more efficiently shared, compared to the case of setting a low maximum bandwidth limit. In the unlimited case, each PCoIP session can use up to 100 Mbps. This provides the user with a more perception-free experience.

You can power the Cisco VXC 2111/2211 using a Cisco PWR-CUBE-4 power adapter or using standard
Power over Ethernet (PoE). This appendix describes the Cisco VXC configurations that are supported by the IEEE 802.3af and IEEE 802.3at PoE standards, by Cisco Universal Power Over Ethernet (UPOE), and by the Cisco PWR-CUBE-4 power adapter.
Cisco VXC 2111/2211 USB ports are compliant with USB 2.0 standard specifications to deliver a maximum power level of 2.5 watts.
The USB ports on the Cisco VXC 2111/2211 operate at two power levels:
•
•
Low: 0.5 watts
High: 2.5 watts
USB ports that operate at the low-power level can only power USB devices that consume up to 0.5 watts of power, and USB ports that operate at the high-power level can power USB devices that consume up to 2.5 watts of power.
USB ports on the Cisco VXC 2111/2211 that operate at high power cannot individually power any noncompliant USB accessory that requires more than 2.5 watts of power. To power devices that require between 2.5 and 5 watts of power, you can use a USB Y cable to connect the accessory to USB port 3 and 4 of the client (when these are operating at high power).
In addition, if no device is connected to a port, the Cisco VXC 2111/2211 cannot reallocate the available power from this port to a device on another port. For example, if USB ports 1 and 2 are operating at low power, and no device is connected to port 2, the Cisco VXC 2111/2211 cannot redirect the power allocated to port 2 to power a high-power device on port 1. In this case, the maximum power limit on port 1 remains unchanged at 0.5 watts.
Low-power USB devices (0.5 watts or less) are typically keyboards, mice, and joysticks, while high-power USB devices (greater than 0.5 watts) are typically bus-powered cameras, hubs, and some
USB Flash drives.
USB ports on the Cisco VXC 2111/2211 can power a USB hub provided the hub does not draw more power than is available from the USB port to which it is connected (that is, 0.5 watts on low-power ports or 2.5 watts on high-power ports).

Appendix C Cisco VXC 2111/2211 Power Considerations
PoE Power Negotiation
When the Cisco VXC 2111/2211 is powered using PoE, the firmware performs a one-time negotiation of PoE power requirements at boot time and allocates the available power to the USB ports, power indicators, and monitors, as described in
Cisco VXC 2111 Power Support, page C-2
and
2211 Power Support, page C-3 . During normal operation, this power allocation does not change.
Table C-1 describes the power configurations that are supported on the Cisco VXC 2111.
Note •
•
IEEE 802.3af PoE does not support Cisco VXC 2111 configurations.
IEEE 802.3at PoE does not support the Cisco VXC 2111 if a Key Expansion Module is attached to a Cisco Unified IP Phone 8961, 9951, or 9971.

The values listed are applicable to Cisco VXC 2111 devices with a version ID (VID) of V02. The behavior may differ on Cisco VXC 2111 devices with a VID of V01. For example, while operating in certain moderate configurations, the Port 1 monitor may not be available on devices with a VID of V01.
You can obtain the VID value from the compliance label on the underside of the device. The VID is listed at the end of the Product ID (PID). For example,
CVXC-2111-W-K9 V01 indicates a V01 device and CVXC-2111-W-K9 V02 indicates a V02 device.
As an alternative to PoE, the Cisco PWR-CUBE-4 power adapter can support a Cisco VXC 2111 attached to a Cisco Unified IP Phone 8961, 9951, or 9971 (with or without camera) with up to three Key
Expansion Modules in a basic configuration (keyboard, mouse, and one monitor).

•
The Unified IP Phone PC port can provide the network connectivity for the Cisco VXC 2211; however, it does not provide power for the device. A power adapter is required when you use the
