For the Clustering configuration, you should have only one valid IP for the Master and invalid IPs for the Slave(s). 
 
 
- Master Configuration: 
 
conf.eth_ip (invalid IP) 
conf.eth_mask (network mask) 
conf.eth_ip_alias (valid IP) 
conf.eth_mask_alias (network mask) 
 
all.socket_port 70nn 
all.protocol socket_server or socket_ssh 
all.authtype radius/loca/none 
all.ipno (ip for the ports) 
##all.ipno is applied only for the MASTER ports## 
 
#local serial ports 
 
s1.tty ttyS1 
s2.tty ttyS2 

s4.tty ttyS4  
s5.tty ttyS5 

s8.tty ttyS8  
s9.tty ttyS9 

s16.tty ttyS16  
s17.tty ttyS17 
s18.tty ttyS18 

s32.tty ttyS32

# Slave ports (in the sequence of the local ports) 
 
s33.tty (*) 
s33.tty :socket_port (*) 
s33.serverfarm  
 
s34.tty  
s34.serverfarm  
 
snn.tty ttySnn (last port of the last Slave unit). 

(*) See the Portserver CM32 manual for more details about these two options. 
 
 
- Slave configuration: 
 
conf.eth_ip  
conf.eth_mask  
 
all.protocol socket_server #it cannot be socket_ssh! 
all.authtype none # it must be ´none´! 
all.socket_port 7033+

s1.tty ttyS1 
s4.tty ttyS4 
s8.tty ttyS8 
s16.tty ttyS16 
s32.tty ttyS32 

(*) Refer to the Portserver CM32 Manual for more info about Clustering. 
 
 
EXAMPLE of CLUSTERING CONFIGURATION 
Below is just an example of how the configuration would be for the 
Master and Slave(s): 
 
Master: CM32 
Slave 1: CM32 
Slave 2: CM32 
 
- IP address of your network 
200.150.100.0/255.255.255.0 
 
- IP address of your clustering network 
10.10.10.0/255.255.255.0 
 
- primary IP of the Master (for the clustering) 
10.10.10.1/255.255.255.0 
 
- secondary IP of the Master (for your network to communicate to the other machines) 
200.150.100.1/255.255.255.0 
 
- primary IP of the Slave 1 (for the clustering) 
10.10.10.20/255.255.255.0 
 
- primary IP of the Slave 2 (for the clustering) 
10.10.10.21/255.255.255.0 
 
- hostname of the Master 
CM32-Master 
 
- a Sun Server connected to port 4 of Slave 1. 
 
- alias of the port 4 in the Slave 1. 
Eagle-Server 
 
 
***Master configuration:

conf.eth_mask_alias 255.255.255.0

all.protocol socket_server (for telnet) or 
socket_ssh (for ssh) 
 
all.authtype local (or radius, or none)
