Configuring G250/G350 options

The G250/G350 provides the following configuration options to help you ensure continuous telephone services:

You can configure the G250/G350 to use up to four MGCs. If the MGC is an S8700, S8710, S8720, or S8730, the first server on the list will normally be the primary C-LAN board connected to the S8xxx server. If the MGC is an S8400 or S8500, the first server on the list will be either the primary C-LAN board connected to the S8xxx server or an Ethernet port on the server that has been enabled for processor Ethernet connections. If the MGC is an S8300, the first server on the list will be the IP address of the S8300. The remaining servers will be alternate C-LAN boards connected to the S8xxx server (S8400, S8500, or S8700-series servers), an S8300 configured as an LSP, or the port enabled as the Ethernet processor port on an S8500 configured as an LSP.

Using the connection preserving migration feature, you can configure the G250/G350 to preserve the bearer paths of stable calls in the event that the G250/G350 migrates to another MGC (including an LSP), including migration back from an LSP to the primary MGC. A call for which the talk path between parties in the call has been established is considered stable. A call consisting of a user listening to announcements or music is not
