Руководство По Установке для Cisco Cisco Unified IP Interactive Voice Response (IVR) 8.0(1)

To check connectivity, perform basic name resolution tests by following this 
procedure on each server in the Cisco CRS network:

At a command prompt, enter hostname

The output of this command indicates the host name of the server. Make a note of 
this name.

At a command prompt, enter ipconfig

The output of this command indicates the IP address of each NIC on the server. 
Make a note of this output.

At a command prompt, enter ping hostname, where hostname is the host name 
that you determined in 

.

The output of this command should be the IP address of the NIC that is used for 
the Cisco CRS server. It should not be the IP Address of the NIC that is used for 
voice monitoring. The voice monitoring NIC should bind to the second NIC in the 
TCP/IP binding order.

At a command prompt, enter ping -a IP_address, where IP_address is the IP 
address that you determined in 

The output of this command should be the same host name that you determined 
with the hostname command. If not, there is an issue with the hosts file or with 
DNS, which you should address before installing Cisco CRS.

At a command prompt, enter ping servername, where servername is the host 
name of the server to which you want to verify IP connectivity.

In the output from this command:

Make sure that only 

Reply from IP_address....

 appears in the output. If a 

message such as 

Request Timed Out

 or 

Destination Unreachable

 appears, 

there are IP routing issues or networking issues between the servers. You 
should address these issues before installing Cisco CRS.

Make sure that 

Ping request could not find host hostname...

 does not 

appear. If it does, there is likely a DNS issue, such as a host name that does 
not exist or a DNS server that cannot be reached. You should address this 
issue before installing Cisco CRS.
