Debug Commands
The commands in this section are for troubleshooting the GGSN. For information about other debug commands, see the Cisco IOS Debug Command Reference.
This chapter contains the following command:
•debug gprs gtp ppp-regeneration
debug gprs dfp
To display debug messages for GPRS DFP weight calculation, use the debug gprs dfp privileged EXEC command. To disable debugging output, use the no form of this command.
debug gprs dfp
no debug gprs dfp
Syntax Description
This command has no arguments or keywords.
Defaults
No default behavior or values.
Command History
Usage Guidelines
See the following caution before using debug commands:
This command displays debug messages for GPRS DFP weight calculation. To display debug messages for the DFP agent subsystem, use the debug ip dfp agent command.
Examples
The following example configures a debug session to check all GPRS DFP weight calculation:
Router# debug gprs dfp
GPRS DFP debugging is on
Router#
The following example stops all debugging:
Router# no debug all
All possible debugging has been turned off
Router#
debug gprs dhcp
To display information about Dynamic Host Configuration Protocol (DHCP) processing on the GGSN, use the debug gprs dhcp privileged EXEC command. To disable debugging output, use the no form of this command.
debug gprs dhcp
no debug gprs dhcp
Syntax Description
This command has no arguments or keywords.
Defaults
No default behavior or values.
Command History
Usage Guidelines
This command is useful for system operators and development engineers if problems are encountered with DHCP processing on the GGSN. To display standard debug messages between the DHCP client on the router and a DHCP server, you can also use the debug dhcp or debug dhcp detail commands with the debug gprs dhcp command.
Examples
The following example shows sample output for DHCP processing on the GGSN:
Router# debug gprs dhcp
2d13h: GPRS:DHCP req:TID 1111111100000099, Req 1
2d13h: GPRS:Requesting IP address for pdp 1111111100000099 from server 172.16.0.8 tableid 0
2d13h: GPRS:DHCP ip allocation pass (10.88.17.43) for pdp 1111111100000099
2d13h: GPRS:Using DHCP ip address 10.88.17.43 for pdp 1111111100000099
The following example shows sample output for standard debug messaging for DHCP processing on the router between the DHCP client and a DHCP server:
2d13h: DHCP: proxy allocate request
2d13h: DHCP: new entry. add to queue
2d13h: DHCP: SDiscover attempt # 1 for entry:
2d13h: DHCP: SDiscover: sending 283 byte length DHCP packet
2d13h: DHCP: SDiscover with directed serv 172.16.0.8, 283 bytes
2d13h: DHCP: XID MATCH in dhcpc_for_us()
2d13h: DHCP: Received a BOOTREP pkt
2d13h: DHCP: offer received from 172.16.0.8

2d13h: DHCP: SRequest- Requested IP addr option: 10.88.17.43
2d13h: DHCP: SRequest placed lease len option: 604800
2d13h: DHCP: SRequest: 301 bytes
2d13h: DHCP: SRequest: 301 bytes
2d13h: DHCP: XID MATCH in dhcpc_for_us()
2d13h: DHCP: Received a BOOTREP pkt

Examples
The following example enables the display of events related to GTP processing on the GGSN:
Router# debug gprs gtp events
The following example enables the display of GTP signaling messages:
Router# debug gprs gtp messages

Router# debug gprs gtp ppp details
Router# debug gprs gtp ppp events
debug gprs gtp-director
To display information about the GTP Director Module (GDM), use the debug gprs gtp-director privileged EXEC command. To disable debugging output, use the no form of this command.
debug gprs gtp-director {events | packets}
no debug gprs gtp-director {events | packets}
Syntax Description
events |

packets |
Displays packets that are sent between GDM and a GGSN. |
Defaults
No default behavior or values.
Command History
Usage Guidelines
This command is useful for system operators and development engineers if problems are encountered with communication between GDM and an SGSN, or between GDM and a GGSN.
Examples
The following debug examples provide sample output for a create PDP context request, delete PDP context request, and clear PDP context using PPP regeneration on the GGSN. The first three examples show output related to debug events messaging only. The last three examples show output while both debug events and details are enabled on the GGSN.
Example 1
The following example displays events related to PPP regeneration processing for a create PDP context requested received by the GGSN:

debug gprs gtp parsing
To display information about the parsing of GPRS Tunneling Protocol (GTP) information elements (IEs) in signaling requests, use the debug gprs gtp parsing privileged EXEC command. To disable debugging output, use the no form of this command.
debug gprs gtp parsing
no debug gprs gtp parsing
Syntax Description
This command has no arguments or keywords.
Defaults
No default behavior or values.
Command History
Usage Guidelines
This command is useful for system operators and development engineers to verify parsing of GTP IEs in signaling requests that are received by GDM or by the GGSN. If the packet is parsed successfully, you will receive a message along with the TID for the packet as shown in the following example:
GPRS:TID:7300000000000000:Packet Parsed successfully
The debug gprs gtp parsing command can be used to verify GDM or GGSN processing of IEs.
Examples
The following example enables the display of debug messages that occur while GDM or the GGSN parses GTP IEs:
Router# debug gprs gtp parsing
debug gprs gtp ppp
To display information about PPP PDP type processing on the GGSN, use the debug gprs gtp ppp privileged EXEC command. To disable debugging output, use the no form of this command.
debug gprs gtp ppp {events | details}
no debug gprs gtp ppp {events | details}
Syntax Description
events |
Displays messages specific to certain conditions that are occurring during PPP PDP type processing. |
details |
Displays more extensive and lower-level messages related to PPP PDP type processing. |
Defaults
No default behavior or values.
Command History
Usage Guidelines
This command is useful for system operators and development engineers if problems are encountered with PPP PDP type processing on the GGSN.
You can enable both forms of the debug gprs gtp ppp command at the same time, as separate command line entries. The events keyword generates output specific to certain conditions that are occurring, which helps qualify the output being received using the details option.
Examples
The following debug examples provide sample output for a create PDP context request and clear PDP context using PPP PDP type on the GGSN. The examples show output while both debug events and details are enabled on the GGSN.
Example 1
The following example displays details and events output related to PPP PDP context processing for a create PDP context requested received by the GGSN:
Router# debug gprs gtp ppp events
GTP PPP events display debugging is on
Router# debug gprs gtp ppp details
GTP PPP details display debugging is on

debug gprs gtp ppp-regeneration
To display information about PPP regeneration processing on the GGSN, use the debug gprs gtp ppp-regeneration privileged EXEC command. To disable debugging output, use the no form of this command.

no debug gprs gtp ppp-regeneration {events | details}
Syntax Description
