Table 3‑10. PCoIP Client Session Variables (Continued)
Setting Description
Configure SSL
protocols
Congures the OpenSSL protocol to restrict the use of certain protocols before establishing
an encrypted SSL connection. The protocol list consists of one or more OpenSSL protocol
strings separated by colons. All cipher strings are case insensitive.
The default value is TLS1.1:TLS1.2, which means that TLS v1.1 and TLS v1.2 are enabled
and SSL v2.0, SSLv3.0, and TLS v1.0 are disabled.
If this seing is set in both the client and the agent, the OpenSSL protocol negotation rule is
followed.
Configure the Client
PCoIP UDP port
Species the UDP client port that is used by software PCoIP clients. The UDP port value
species the base UDP port to use. The UDP port range value determines how many
additional ports to try if the base port is not available.
The range spans from the base port to the sum of the base port and port range. For example,
if the base port is 50002 and the port range is 64, the range spans from 50002 to 50066.
This seing applies to the client only.
By default, the base port is 50002 and the port range is 64.
Configure the maximum
PCoIP session
bandwidth
Species the maximum bandwidth, in kilobits per second, in a PCoIP session. The
bandwidth includes all imaging, audio, virtual channel, USB, and control PCoIP trac.
Set this value to the overall capacity of the link to which your endpoint is connected, taking
into consideration the number of expected concurrent PCoIP sessions. For example, with a
single-user VDI conguration (a single PCoIP session) that connects through a 4Mbit/s
Internet connection, set this value to 4Mbit, or 10% less than this value to leave some
allowance for other network trac. When you expect multiple concurrent PCoIP sessions to
share a link, comprising either multiple VDI users or an RDS conguration, you might want
to adjust the seing accordingly. However, lowering this value will restrict the maximum
bandwidth for each active session.
Seing this value prevents the agent from aempting to transmit at a higher rate than the
link capacity, which would cause excessive packet loss and a poorer user experience. This
value is symmetric. It forces the client and agent to use the lower of the two values that are
set on the client and agent side. For example, seing a 4Mbit/s maximum bandwidth forces
the agent to transmit at a lower rate, even though the seing is congured on the client.
When this seing is disabled or not congured on an endpoint, the endpoint imposes no
bandwidth constraints. When this seing is congured, the seing is used as the endpoint's
maximum bandwidth constraint in kilobits per second.
The default value when this seing is not congured is 900000 kilobits per second.
This seing applies to the agent and the client. If the two endpoints have dierent seings,
the lower value is used.
Configure the PCoIP
session bandwidth
floor
Species a lower limit, in kilobits per second, for the bandwidth that is reserved by the
PCoIP session.
This seing congures the minimum expected bandwidth transmission rate for the
endpoint. When you use this seing to reserve bandwidth for an endpoint, the user does not
have to wait for bandwidth to become available, which improves session responsiveness.
Make sure that you do not over-subscribe the total reserved bandwidth for all endpoints.
Make sure that the sum of bandwidth oors for all connections in your conguration does
not exceed the network capability.
The default value is 0, which means that no minimum bandwidth is reserved. When this
seing is disabled or not congured, no minimum bandwidth is reserved.
This seing applies to the agent and the client, but the seing only aects the endpoint on
which it is congured.
When this seing is modied during an active PCoIP session, the change takes eect
immediately.
