Cross-Checking Configuration Files
Cross-check the configuration files by entering the following command:
debug ss7 mtp2 iac 0
You should see a response like the following Cisco PGW 2200 Softswitch sample configuration file:
File: XECfgParm.dat (extract)
*.ipAddrLocalA = 10.15.13.6 # Should be same as *.IP_Addr1
*.ipAddrLocalB = 10.15.13.22
*.ipAddrPeerA = 0.0.0.0 # Failover peer's address
*.ipAddrPeerB = 0.0.0.0
*.IP_Addr1 = 10.15.13.6 # Address of interface on motherboard
*.IP_Addr2 = 10.15.13.22
*.IP_Addr3 = 0.0.0.0
*.IP_Addr4 = 0.0.0.0
*.stPort = 0
This file defines the Cisco PGW 2200 Softswitch IP addresses that are used to communicate with the
Cisco ITP-L.

Cisco PGW 2200
Softswitch is
exchanging messages
with remote STP.
Exchanged point
codes must match
before
communication can
be established
successfully.
Checkpoint codes in the outgoing RUDP message:
in data 0xC10E0519 0x111180A5:
The part in bold-face type should be read as
11 19 05 0E C1 and converted in bit-swapped HEX:
0001000100011001000001010000111011010001.
1. The HEX part in bold-face type is the point code
of the Cisco PGW 2200 Softswitch, 0.161.6.
2. The HEX part in italic type is the point code of
the STP in this example, 0.140.4.
Checkpoint codes in the incoming RUDP message:
in data 0xF1648443 0x112180A5:
The part in bold-face type should be read
11 43 84 64 F1 and converted in bit-swapped HEX:
0001000101000011100001000110010011110001.
1. The HEX part in bold-face type is the point code
of the STP, 0.140.4.
2. The HEX part in italic type is the point code of
the Cisco PGW 2200 Softswitch, 0.161.6.
The values in the incoming and outgoing messages
must match.
