Cisco PGW 2200 Softswitch Release 9.8 Software Installation and Configuration Guide
OL-18083-01
Chapter 4 Configuring the Cisco PGW 2200 Softswitch Software
Configuring the Execution Environment
Note If there are two Ethernet interfaces defined on the Cisco PGW 2200 Softswitch, it is mandatory to have
these on distinct subnets.
For example, consider the following configuration:
*.IP_AddrLocalA = 172.22.119.108
*.IP_AddrLocalB = 172.22.119.54
This is not a valid combination because they are on the same subnet. The following example illustrates
a valid combination:
*.IP_AddrLocalA = 172.22.119.108
*.IP_AddrLocalB = 172.22.120.54
In this example, the subnet mask is 255.255.255.0 (or 255.255.255.128).
If the two Ethernet interfaces are on the same subnet, then one of them must be physically disconnected
from the existing subnet and then connected to a different subnet. The new IP address must be
appropriately configured on the system. Refer to the manual pages for the UNIX command ifconfig for
more information.
Parameter Modification
*.IP_AddrLocalA Enter the first local IP address; used for checkpointing and
switchover heartbeats.
Caution This address is the same value as *.IP_Addr1, and
is the bge0 interface.
Caution No other machine on the network should have
*.IP_AddrLocalA set to 0.0.0.0.
*.IP_AddrPeerA Enter the first corresponding peer IP address; used for
checkpointing and switchover heartbeats.
Note If you have two Cisco PGW 2200 Softswitch hosts in
a fault tolerant configuration, this value is set to the IP
address of the second host.
*.IP_AddrLocalB Enter the second local IP address; used for checkpointing and
switchover heartbeats. This is the address of the bge1
interface.
Note If your configuration does not use a secondary
Ethernet adapter, leave this address set to the default
value, 0.0.0.0.
*.IP_AddrPeerB Enter the second corresponding peer IP address; used for
checkpointing and switchover heartbeats. This is the address
of the bge1 interface on the second host.
Note If your configuration does not use a secondary
Ethernet adapter, leave this address set to the default
value, 0.0.0.0.
