FTOS displays debug messages on the console. To view which debugging commands are enabled, use the 
show debugging command in EXEC Privilege mode.
Use the keyword no followed by the debug command To disable a specific debug command. For example, 
to disable debugging of BGP updates, enter 
no debug ip bgp updates command. 
Use 
no debug ip bgp to disable all BGP debugging. 
Use 
undebug all to disable all debugging.
Storing Last and Bad PDUs
FTOS stores the last notification sent/received, and the last bad PDU received on per peer basis. The last 
bad PDU is the one that causes a notification to be issued. These PDUs are shown in the output of the 
command 
show ip bgp neighbor, as shown in Figure 10-34.
debug ip bgp {ip-address | 
peer-group-name} soft-reconfiguration
EXEC Privilege
Enable soft-reconfiguration debug. Enable 
soft-reconfiguration debug.
To enhance debugging of soft reconfig, use 
the following command only when 
route-refresh is not negotiated to avoid the 
peer from resending messages:
bgp soft-reconfig-backup
In-BGP is shown via the show ip 
protocols
 command.
