Determine if the problem is an IP address or port configuration mismatch between the ITP and the BTS
Step 2
10200.
a.
Determine the BTS 10200 configured values for the BTS 10200 IP addresses and port. Look for the
DNS name and port number that are configured for the SGA process in
/opt/OptiCall/CA146/bin/platform.cfg. Go to the specified directory and enter:
cat platform.cgf | grep mdl
The output will look similar to the following:
Args=-t 1 -h mgcp-HRN11CA.hrndevtest.cisco.com -p 11146 -mdldir. /mdl -mdltracedir
../mdltrace -mdltestmode 0 -mdlloadmdo 0 -mdltriggertimer 200 -mdlgarbagetimer 5146

Determine the ITP configured values of the ITP BTS 10200 IP addresses and port.

Determine the BTS 10200 configured values for the ITP IP addresses and port
c.
On the BTS 10200 EMS CLI console, type the following:
CLI> show sctp-assoc id=<SCTP assoc id>
An example of the output will show the IP addresses and port as follows:
REMOTE_PORT=2905
REMOTE_TSAP_ADDR1=10.0.1.54
REMOTE_TSAP_ADDR2=10.128.1.239
OL-8723-19
The local IP port number is shown directly after the -p option.
The local IP addresses that are used by the BTS 10200 are derived from the DNS name, which
is given directly after the -h option. At the BTS 10200 UNIX prompt, enter:
NSlookup <DNS name>
The output will look similar to the following:
Server:
hrnbtsjs-1.cisco.com
Address:
10.82.70.199
Name:
mgcp-HRN11CA.hrndevtest.cisco.com
Addresses:
10.0.5.136, 10.128.1.147
The BTS 10200 configured local IP addresses are given in the Addresses: line.
Log on to the ITP and get into enable mode.
Enter the following command:
show run
Hit enter until the ASP configurations are displayed. A section similar to the following will
appear which shows you the ITP configured values for the BTS 10200 IP addresses of the SCTP
association:
cs7 asp hrn11asp 11146 2905 m3ua
remote-IP 10.0.5.136
remote-IP 10.128.1.147
The number after the ASP name "hrn11asp" is the port number that the ITP has configured for
the BTS 10200 side of the SCTP association. The two remote-IP addresses are the addresses
that the ITP has configured for the BTS 10200 side of the SCTP association. Make sure all of
these values match the values found in Step 2A.
