Setting Up Desktop and Application Pools in View

Table 16‑5. View PCoIP General Session Variables (Continued)
Setting Description
Configure the TCP port to which the
PCoIP host binds and listens
Specifies the TCP agent port bound to by software PCoIP hosts.
The TCP port value specifies the base TCP port that the agent attempts
to bind to. The TCP port range value determines how many additional
ports to try if the base port is not available. The port range must be
between 1 and 10.
The range spans from the base port to the sum of the base port and port
range. For example, if the base port is 4172 and the port range is 10, the
range spans from 4172 to 4182.
Do not set the size of the retry port range to 0. Setting this value to 0
causes a connection failure when users log in to the desktop with the
PCoIP display protocol. Horizon Client returns the error message, The
Display protocol for this desktop is currently not
available. Please contact your system administrator.
This setting applies to View Agent only.
On single-user machines, the default base TCP port is 4172 in View 4.5
and later. The default base port is 50002 in View 4.0.x and earlier. By
default, the port range is 1.
On RDS hosts, the default base TCP port is 4173. When PCoIP is used
with RDS hosts, a separate PCoIP port is used for each user connection.
The default port range that is set by the Remote Desktop Service is large
enough to accommodate the expected maximum of concurrent user
connections.
IMPORTANT As a best practice, do not use this policy setting to change
the default port range on RDS hosts, or change the TCP port value from
the default of 4173. Most important, do not set the TCP port value to
4172. Resetting this value to 4172 will adversely affect PCoIP
performance in RDS sessions.
Configure the UDP port to which the
PCoIP host binds and listens
Specifies the UDP agent port bound to by software PCoIP hosts.
The UDP port value specifies the base UDP port that the agent attempts
to bind to. The UDP port range value determines how many additional
ports to try if the base port is not available. The port range must be
between 1 and 10.
Do not set the size of the retry port range to 0. Setting this value to 0
causes a connection failure when users log in to the desktop with the
PCoIP display protocol. Horizon Client returns the error message, The
Display protocol for this desktop is currently not
available. Please contact your system administrator.
The range spans from the base port to the sum of the base port and port
range. For example, if the base port is 4172 and the port range is 10, the
range spans from 4172 to 4182.
This setting applies to View Agent only.
On single-user machines, the default base UDP port is 4172 for View 4.5
and later and 50002 for View 4.0.x and earlier. By default, the port range
is 10.
On RDS hosts, the default base UDP port is 4173. When PCoIP is used
with RDS hosts, a separate PCoIP port is used for each user connection.
The default port range that is set by the Remote Desktop Service is large
enough to accommodate the expected maximum of concurrent user

the default port range on RDS hosts, or change the UDP port value from
the default of 4173. Most important, do not set the UDP port value to
4172. Resetting this value to 4172 will adversely affect PCoIP
performance in RDS sessions.
