194 Installing and Upgrading the Avaya G700 Media Gateway and Avaya S8300 Media Server
All phones for which the DHCP server has an LSP as the second address in the MCIPADD list
should be administered to be in the same network region. Or, if administered to be in different
network regions, the network regions involved should be interconnected. Use the
ip-network-map form on the primary controller to put the IP phones in the same network region.
On the ip-network-map form, a range of IP addresses (or a subnet) can be specified to be in a
single network region. Enter the IP address range, or subnet, that contains the IP addresses of
the IP phones and enter the desired network region number for that address range. The same
address range or subnet must then be administered on the DHCP server. If it is not desired that
all the phones be in the same network region, the form “ip-network-region #” should be used to
interconnect all the network regions that contain those phones.
Transition of Control from Primary Controller to LSP
When the network connection between the G700 and the S8300, S8400, S8500, or
S8700-series primary controller goes down, control of endpoints connected to the G700 goes to
the next point in the primary controller list, which will be either a second CLAN board or the LSP.
At this point, the primary controller alarms to notify the customer and services personnel that the
network connection between the primary controller and G700 has problems. If control passes to
the LSP, the LSP’s license allows it to support the G700 endpoints for up to 30 days, within
which the network problems should be resolved.
The customer may pass control back to the S8300, S8400, S8500, or S8700-series primary
controller manually, by selecting Shutdown this server from the S8300 web page (includes
selecting the option to restart after shutdown), or a technician must run reset system 4 from
the Linux command line. When the system reboots, the G700 and its endpoints reregister with
the primary controller.
The customer may also choose to administer Communication Manager on the System
Parameters Media Gateway Automatic Recovery Rule screen, such that the primary controller
accepts control back from the LSP as soon as possible, based on whether there are calls active
or what time of day it is. See Administrator Guide for Avaya Communication Manager,
03-300509.
