Troubleshooting Signaling Alarms
Determine the ITP configured values of the ITP BTS 10200 IP addresses and port
d.
Determine if all Ethernet connections on the BTS 10200 have been disconnected or if communication
Step 3
has been lost to the IP router. In the platform.log, look for the following ERROR message:
"All the IP interfaces are faulty!!"
If this message is found, the Ethernet connections of the BTS 10200 have been pulled or cut. If this
message is not found, proceed to Step 4.
Step 4 Determine if the problem is an IP routing issue.
Determine what has been provisioned in the BTS 10200 for the destination IP interfaces of the SCTP
a.
association by typing the following command:
show sctp-association id=<sctp-association-id>
Information similar to the following will appear and display the destination IP addresses:
REMOTE_TSAP_ADDR1=10.0.1.54
REMOTE_TSAP_ADDR2=10.128.1.239
Ping each of the destination IP addresses If one of the addresses does not respond to the ping, there

is an IP routing problem that has disabled SCTP communication. Contact the Cisco TAC for
assistance. If the ping commands are successful, proceed to Step 5.
Determine if the BTS 10200 is reachable from the ITP.
Step 5
Log on to the ITP and get into enable mode.
a.
Find the BTS 10200 SCTP association endpoint IP addresses by typing the following command:
b.
show run
Hit enter until the ASP configuration is displayed. A section similar to the following will display
c.
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
Ping each of the IP addresses. If you do not receive a response to the ping command for at least one
d.
of the BTS 10200 IP endpoint addresses, there is an IP routing problem that is causing the SCTP
association to be down. Contact the Cisco TAC for assistance. Otherwise, proceed to Step 6.

Enter sho run.
–
Hit enter until the m3ua (or sua) configuration is displayed. In our example, we are considering
–
the SCTP association connection between the BTS 10200 and the ITP, so we will look at the
ITP m3ua configuration. An example of this is as follows:
cs7 m3ua 2905
local-IP 10.0.1.54
local-IP 10.128.1.239
Make sure that the IP addresses and port number are the same values as found in step 2C.
