Processor Ethernet (PE) is used for IP connectivity.
Note:
Communication Manager IP endpoints can register either to PE . PE resides on the Communication Manager server . Communication Manager can have one PE.
When configuring Communication Manager on a server, the PE interface is assigned to an IP Address on the control network or corporate LAN. Communication Manager establishes a logical connection between the Communication Manager software and the physical port (NIC) for the PE interface.
The PE interface is enabled by default in the license file. The feature keyword FEAT_PRETH must be checked to ON in the license file for PE to work.
A survivable server enables the PE interface automatically. On a survivable remote server, the H.248 and the H.323 fields default to a yes on the IP Interface Procr screen, to allow the registration of H.248 gateways and H.323 endpoints using the PE interface.
The gateway and H.323 endpoint registration on a survivable core server is allowed if you administer the Enable PE for H.248 Gateways and Enable PE for H.323 Endpoints fields on the Survivable Processor screen on the main server. Therefore the H.248 and the H.323 fields on the IP Interface Procr screen of the survivable core server display the values that you administered.
Important:
Both survivable core and remote servers require the use of the PE interface to register to the main server. Do not disable the PE interface.
