Syntax Definitions
value A numeric value (1–10) that controls the transmission of BPDU through
the port.
Defaults
By default, the txholdcount value is set to 3.
Platforms Supported

Usage Guidelines
• This command is an explicit Spanning Tree command that only applies to the CIST instance regard-
less of which operating mode (flat or 1x1) is active on the switch.
• If the switch is running in the 1x1 mode when this command is used, the specified txholdcount status
for the port is not active for the CIST instance until the switch is running in the flat Spanning Tree
mode.
• Note that when a configuration snapshot is taken of the switch, all Spanning Tree commands are saved
in their explicit format.
