Vision2 Network Switch Requirements
Vision
2
requires a Gigabit layer 2/3 network switch with IGMP Snooping/Querier support. The network switch should meet the
following requirements:
Using Vision2 without a DNS Server
Using Vision
2
with a DNS Server is recommended. If a DNS Server is not available, the hosts file will need to be edited on each
Vision
2
server and the names and IP addresses of all your Vision
2
servers added. The hosts file is located in the folder
C:\windows\system32\drivers\etc. FIG. 1 shows a hosts file for a setup with one master server called V2MASTER with IP address
192.168.20.110 and one Digital TV Appliance called V2DVBGATEWAY with IP address 192.168.20.111.
NOTE:
If a DNS server is not available and the name of a server needs to be changed, you will have to update the name of the server
in the host file on each of the servers which make up the Vision
2
system.
