Chapter 6 Troubleshooting the Cisco PGW 2200 Softswitch Platform
Resolving SS7 Network Related Problems
• CPU utilization
• Number of users that are logged in
• Statistics for the Ethernet interfaces
• IP routing
• System setup
• Swap space
• Date and time of last system reboot
• Permissions for the configuration library (CONFIG_LIB)
• File permissions for the /opt/CiscoMGC/etc and /opt/CiscoMGC/bin directories
• Copy of the XECfgParm.dat file
To collect your system data snapshot, perform the following steps:
Step 1 Log in to the active Cisco PGW 2200 Softswitch, and enter the cd /opt/CiscoMGC/local UNIX
command to change directories.
Step 2 Enter the collectdata command to run the system data snapshot script:
The system returns a response that indicates the name of the file and the data path to the file.
Note The name of the log file contains the time stamp when the file was created and the name of the
Cisco PGW 2200 Softswitch. The file is always saved to the opt/CiscoMGC/var/log directory.
Step 3 Provide the log file to the Cisco TAC as instructed by TAC personnel.
Resolving SS7 Network Related Problems
The Cisco PGW 2200 Softswitch platform is a standard Service Switching Point (SSP) in an SS7
network. The SS7 network carries two types of signals:
• Circuit-related
• Noncircuit-related
The signals that are involved in the setup and teardown of bearer circuits are circuit-related. The
Cisco PGW 2200 Softswitch uses non-circuit-related signals for all the ancillary services that the SS7
network provides, including database access and network management.
The SS7 protocol is composed of several levels or parts, including the following:
• Message Transfer Part (MTP)—Levels 1 (MTP1) through 3 (MTP3)
• Signaling Connection Control (SCCP)
• Application Service Part (ASP)
• Transaction Capabilities Application Part (TCAP)
• Telephony User Part (TUP)
• ISDN User Part (ISUP)
