The following table shows how the Processor Ethernet (PE) functionality works on main servers and survivable core servers. For more information on how to administer the PE interface, see Administering page one of the Survivable Processor screen.
Use of Processor Ethernet interface on main servers and survivable core servers
Possible functions of the PE interface
Main server
Survivable core server
Registration
The main server accepts registration messages from a survivable core or remote server through the PE interface.
The use of the PE interface for registration to the main is automatically enabled by the Communication Manager software. The PE interface needs to be configured on the System Management Interface.
Adjunct connectivity
All adjuncts are administered on the IP Services screen on the main server.
You can use the PE interface on a simplex server to connect to three supported adjuncts, AESVCS, CMS, and CDR.
You can use the Process Ethernet interface on a duplex main server to connect to CMS.
You can use the PE interface on a duplex server to connect to CDR, Messaging (all that support IP connectivity) If you connect the gateways to PE on the main server because there are no C-LANs in the system, the gateways should have the PE of the survivable core server as the first entry in the survivable server portion of their MGC list. If C-LANs are present, the MGC list includes C-LAN addresses in the primary portion of their MGC list.
The way adjuncts connect to a survivable core server is administered on the Survivable Processor screen on the main server.
Gateway registration
Administration to allow H.248 registration on the PE interface of a main server is performed on the IP Interfaces screen.
Administration to allow H.248 registration on the PE interface of a survivable core server is performed on the Survivable Processor screen.
