Avaya S8700 Media Server IP Connect High Reliability
Configuration using Avaya P333T and Extreme Summit 48si
Switches for the Control Network - Issue 1.0
Abstract
These Application Notes describe how to provision a sample Avaya S8700 Media Server IP
Connect High Reliability configuration in an Avaya and Extreme control network
environment. The sample IP Connect High Reliability configuration depicted in these
Application Notes is composed of two Avaya G650 carriers, two TN2312BP IPSI circuit
packs (one for each G650 carrier), and separate control networks for each Avaya S8700 Media
Server. The configuration was validated using Avaya P333T and Extreme Summit 48si
switches for the control network.

1. Introduction
These Application Notes describe how to configure a sample Avaya S8700 Media Server IP
Connect High Reliability configuration in an Avaya and Extreme control network environment.
The configuration has been designed so that each control network component is duplicated,
therefore eliminating single points of failure.
High Reliability is available in an IP Connect configuration only when using Avaya G650
carriers, TN2312BP IP Server Interface (IPSI) circuit packs, and Avaya Communication
Manager Release 2.0 or higher. An IP Connect High Reliability configuration requires that the
customer provide two Ethernet switches, one for control network A (CNA), and one for control
network B (CNB). The control network switches do not need to be dedicated. The configuration
also requires two TN2312BP IPSI circuit packs per port network, one for G650 carrier A, and
one for G650 carrier B.
Figures 1 and 2 illustrate the components of the first Avaya S8700 Media Server IP Connect
High Reliability configuration used to verify these Application Notes. In Figure 1, the control
network, which is separate from the bearer network, consists of Avaya P333T switches.

In Figure 2, the control network, which is also separate from the bearer network, consists of
Extreme Summit 48si switches.

Note: These Application Notes assume the Layer 2 and Layer 3 network configurations depicted
in Figures 1 and 2 are already in place. Furthermore, it is assumed that the bearer VoIP network
configuration is also already in place. Consequently, only the configuration related to Avaya IP
Connect High Reliability is addressed. Please consult the appropriate User Guides for more
information on how to setup the remaining components.

3. IP Server Interface (IPSI) Card Configuration
The following procedure shows how to configure the IPSI IP address and default gateway.
•
•
There are two Ethernet ports on each IPSI card. The upper one is the service port with the
pre-configured IP address 192.11.13.6/255.255.255.252 and the lower one is the control
network port. The control network port can be configured through the service port.
Configure a laptop’s IP address to 192.11.13.5/255.255.255.252 and connect its Ethernet
interface to the services port with a crossover Ethernet cable.
Telnet to the services port IP address 192.11.13.6 and type ipsilogin at the IPSI prompt.
Log in to the IPSI card with the default login and password.
Figure 3 shows how to configure the IP address and default gateway for the IPSI connected to
Control Network A. Repeat this configuration for the IPSI connected to Control Network B with
the appropriate IP addresses.

4. Avaya S8700 Media Server Configuration
This section presents configuration steps for the S8700 Media Servers. It is assumed that an
appropriate license file and authentication file have been installed on the server, and that login
and password credentials are available.
The IP identity of the S8700 Media Server is configured using a Web interface. While details of
the web interface are beyond the scope of this document, a few pertinent procedures and screens
are presented here.
To access the web interface, connect a laptop to the services port of one of the S8700 Media
Servers (Ethernet port 1). The services port uses the pre-configured IP address 192.11.13.6 with
mask 255.255.255.252. Configure the laptop’s IP address as 192.11.13.5 with mask
255.255.255.252. Connect the laptop’s Ethernet interface to the services port with a crossover
Ethernet cable. Launch a web browser, turn proxies off, and connect to the URL
http://192.11.13.6. Supply appropriate login and password credentials when prompted to do so.
After login, a main menu is presented along the left hand side. Click “Configure Server” from
the lower left of this main menu. The instructions on the web screens are self-explanatory, and
the relevant screen for server identities and IP address assignment are shown below in Figures 4
and 5. Repeat the procedures described above for the second Avaya S8700 Media Server. The
only difference is to select “2” for the “This is server” field in Figure 4.

5. Avaya Communication Manager Configuration
The next series of steps are performed through the SAT interface. When prompted, supply an
appropriate login and password to log in to the SAT. There are a variety of ways to access the
SAT login prompt. These include:
•
•
Using “telnet 192.11.13.6 5023” from the computer connected to the services port of the
S8700 Media Server. Using 5023 as an argument to telnet brings the user directly to the
SAT without presenting the Linux command line interface. If 5023 is omitted from the
telnet command, simply type “sat” from the Linux prompt.
Using telnet to one of the active IP addresses just assigned to the S8700 Media Server
from the customer’s network (e.g., telnet 178.16.12.100 5023, telnet 178.16.14.100
5023). This approach would not use the direct connection to the services port of the
S8700 Media Server, but rather could be performed from a computer connected to one of
the data control networks.
5.1. Enable IP Port Network Support
Use the change system-parameters customer-options command to enable IP Port Network
support. To enable IP Port Network support, set the “Internet Protocol (IP) PNC?” and the “Port

to enable IP Port Network support.

5.5. Enable IPSI Duplication
IPSI Duplication requires that all IPSI-connected port networks have both primary (CNA) and
secondary (CNB) IPSI circuit packs in each G650 carrier. IPSI Duplication is not supported in a
single G650 carrier. Use the change system-parameters duplication command to enable the
IPSI Control Duplication feature.

Make a phone call from extension 35041 to extension 35042. Verify the 35042 extension rings
and can be answered. Verify two-way talk path exists.
Disconnect the cable connected to the active IPSI. Use the list ipserver-interface command to
verify the control state of the “standby” IPSI in Step 2 has changed to “actv-aa”.
Verify the call stays up between the two stations. Likewise, verify a two-way talk path between
the two stations.

7. Conclusion
As illustrated in these Application Notes, Avaya S8700 Media Servers with Avaya G650 Media
Gateways running in an IP Connect configuration can support a high reliability control network
using existing Avaya and Extreme data infrastructures. Support for the IP Connect High
Reliability configuration was introduced as part of the Avaya Communication Manager Release
2.0. High Reliability was previously only supported in MultiConnect configurations.
