PCoIP Management Console User Manual 1.3.3.4 2. If the transmission times out, the device creates the next FQDN variation by proceeding one level up the domain hierarchy. The last domain name attempted has a single dot in the string. 3. After exhausting the FQDN possibilities (based on the DHCP options 15 string), the device waits for five minutes and then uses hostname variations based on the DHCP options 12 string. 4. After failing to contact a MC using the DHCP options 12 string, the device waits for five minutes and then cycles back to using DHCP options 15. 5. The device repeats this process until a MC is contacted. Example In the following example, the DHCP options 15 returns sales.europe.companyname.com. DHCP options 12 returns hostmachine1.sales.europe.companyname.com. Note that the DHCP server may return no value for either option. The MC configured the PCoIP MC DNS-Based Discovery Prefix setting in the device to equal pcoip_mc1. The device creates the following FQDNs and sequentially attempts contact with the MC: (attempt #1) pcoip_mc1.sales.europe.companyname.com (attempt #2) pcoip_mc1.europe.companyname.com (attempt #3) pcoip_mc1.companyname.com (attempt #4) pcoip_mc1.hostmachine1.sales.europe.companyname.com (attempt #5) pcoip_mc1.sales.europe.companyname.com (attempt #6) pcoip_mc1.europe.companyname.com (attempt #7) pcoip_mc1.companyname.com (attempt #8) pcoip_mc1.sales.europe.companyname.com (repeat 1-7) ... Attempts 1 to 3 use the domain name from DHCP options 15 string. Failing to contact the MC, the device uses the DHCP options 12 string for attempts 4 to 7. Failing transmissions for attempt 4 to 7, the device cycles back to using DHCP options 15. Manual Device Discovery Manual device discovery is not an automated discovery mechanism. This mechanism supports discovering devices that are powered on and connected to the network when the MC is commanded to discover devices. The MC supports manually discovering devices at a specific IP address, in a range of IP addresses or at an FQDN. This option is useful to quickly begin using the MC or when a deployment uses the PCoIP MC DNS-Based Discovery Prefix configuration setting described in section 1.3.3.2. In this situation, you can discover devices using this feature and configure the PCoIP MC DNS-Based Discovery Prefix setting of each device so the devices contact the MC each time they boot.

2.
If the transmission times out, the device creates the next FQDN variation by proceeding
one level up the domain hierarchy. The last domain name attempted has a single dot in
the string.
3.
After exhausting the FQDN possibilities (based on the DHCP options 15 string), the
device waits for five minutes and then uses hostname variations based on the DHCP
options 12 string.
4.
After failing to contact a MC using the DHCP options 12 string, the device waits for five
minutes and then cycles back to using DHCP options 15.
5.
The device repeats this process until a MC is contacted.
Example
In the following example, the DHCP options 15 returns sales.europe.companyname.com.
DHCP options 12 returns hostmachine1.sales.europe.companyname.com. Note that the
DHCP server may return no value for either option. The MC configured the
PCoIP MC
DNS-Based Discovery Prefix
setting in the device to equal
pcoip_mc1
.
The device creates the following FQDNs and sequentially attempts contact with the MC:
(attempt #1) pcoip_mc1.sales.europe.companyname.com
(attempt #2) pcoip_mc1.europe.companyname.com
(attempt #3) pcoip_mc1.companyname.com
<device delays for 5 minutes>
(attempt #4) pcoip_mc1.hostmachine1.sales.europe.companyname.com
(attempt #5) pcoip_mc1.sales.europe.companyname.com
(attempt #6) pcoip_mc1.europe.companyname.com
(attempt #7) pcoip_mc1.companyname.com
<device delays for 5 minutes>
(attempt #8) pcoip_mc1.sales.europe.companyname.com (repeat 1-7)
...
Attempts 1 to 3 use the domain name from DHCP options 15 string. Failing to contact the
MC, the device uses the DHCP options 12 string for attempts 4 to 7. Failing transmissions for
attempt 4 to 7, the device cycles back to using DHCP options 15.

Manual Device Discovery
Manual device discovery is not an automated discovery mechanism. This mechanism
supports discovering devices that are powered on and connected to the network when the MC
is commanded to discover devices.
The MC supports manually discovering devices at a specific IP address, in a range of IP
addresses or at an FQDN. This option is useful to quickly begin using the MC or when a
deployment uses the
PCoIP MC DNS-Based Discovery Prefix
configuration setting
described in section 1.3.3.2. In this situation, you can discover devices using this feature and
configure the PCoIP MC DNS-Based Discovery Prefix setting of each device so the devices
contact the MC each time they boot.
