Enable soft-reconfiguration debug.
EXEC Privilege mode
debug ip bgp {
ip-address
|
peer-group-name
} soft-reconfiguration
To enhance debugging of soft reconfig, use the
bgp soft-reconfig-backup
command only when route-refresh is not negotiated
to avoid the peer from resending messages.
In-BGP is shown using the
show ip protocols
command.
Dell Networking OS displays debug messages on the console. To view which debugging commands are enabled, use the
show
debugging
command in EXEC Privilege mode.
To disable a specific
debug
command, use the keyword
no
then the
debug
command. For example, to disable debugging of BGP updates,
use
no debug ip bgp updates
command.
To disable all BGP debugging, use the
no debug ip bgp
command.
To disable all debugging, use the
undebug all
command.
Storing Last and Bad PDUs
Dell Networking OS stores the last notification sent/received and the last bad protocol data unit (PDU) received on a per peer basis. The
last bad PDU is the one that causes a notification to be issued.
In the following example, the last seven lines shown in bold are the last PDUs.
Example of the
show ip bgp neighbor
Command to View Last and Bad PDUs
Dell(conf-router_bgp)#do show ip bgp neighbors 1.1.1.2
