Each command is listed, in detail, in the following sections.
debug stp config ports
Purpose
This command used to configure per-port STP debug level on the specified ports.
Syntax debug stp config ports [<portlist> | all] [event | bpdu | state_machine | all] state
[disable | brief | detail]
Description
This command used to configure per-port STP debug level on the specified ports.
Parameters ports - Specifies the STP port range to debug.
<portlist> - Enter the list of port used for this configuration here.
all - Specifies to debug all ports on the Switch.
event - Debug the external operation and event processing.
bpdu - Debug the BPDU’s that have been received and transmitted.
state_machine - Debug the state change of the STP state machine.
all - Debug all of the above.
state - Specifies the state of the debug mechanism.
disable - Disables the debug mechanism.
brief - Sets the debug level to brief.
detail - Sets the debug level to detail.
Restrictions
Only Administrator and Operator-level users can issue this command.
Example usage:
To configure all STP debug flags to brief level on all ports:
DES-3528:admin# debug stp config ports all all state brief
Command: debug stp config ports all all state brief
Warning: only support local device.
Success.
