Hi pls provide us the configuration for using the Cisco 2811 Router with 16Port Async Module as the terminal server, we have given the below mentioned config in the router
ip host R1 2066 223.255.255.254
ip host R2 2067 223.255.255.254
ip host R3 2068 223.255.255.254
ip host R4 2069 223.255.255.254
ip host R5 2070 223.255.255.254

The commands mean that R1's console is connected using the first RJ-45 cable and is available on port 2001, R2's console is connected using the second RJ-45 cable and is available on port 2002 and so on. Remember that the ports are numbered as 2000 plus the line number. Hence, the first port is 2001. If you have more than eight devices and have connected a second CAB-OCTAL-ASYNC cable then you need to add a similar configuration line with the port numbers starting from 2009 till 2016.
In your configuration u configured 9 ports. So please add second cable for another 8 ports.
To connect to the console of a device, telnet to the terminal server router's loopback address and specify the port number associated to the device. For example, to connect to console of router R1 (from our example) type telnet 192.168.12.1 2001 in the Run dialog box from your PC.
