Powering up/Booting or connecting a Poly Poly Studio X or G7500 to a network switch initiates certain network Protocols
NOTE: The below has been tested with a Studio X50 running Software 3.13
INITIAL BOOT PROCESS
Within this DHCP Discover message, the phone uses various Sub-Options
- Option 12 Host Name
The above can be used to identify the device in the Network
- Option 55 is actually a List of Sub Options
For Studio X or G7500 option 66 or 160 is used to discover the location of the provisioning Server being used. The section "Onboard Video Devices via the DHCP Auto Discovery" has more details on this.
- 42 like 4 can be used to set the => time <= on the device
- 15 can be used so the phone can identify the Domain it is using
- 6 is to identify the DNS / Domain Name server(s)
- 4 like 42 can be used to set the => time <= on the device
- 3 requests the default router or => gateway address <=
- 1 request's the phones => subnet address <=
- Option 60 Identifies the Vendor Class Identifier for Studio X or G7500
TC8
More details on the Poly Phone DHCP Vendor Option can be found in the => Technical Bulletin 54041 <= and troubleshooting => here <=. The same is applicable to Poly Studio X or G7500
Once the device has an IP it will attempt to connect to Poly Lens and other locations:
The TC8, G7500 or Studio X are then joining the Multicast group 224.0.0.251
The TC8 then uses 224.0.0.200 to advertise and pair with a compatible device
