messages. Alternatively, the messages can be directed to any of the other log
outputs by adding a filter for the MSTP application using
command:

Usage 2 Use the debug mstp packet rx|tx decode interface command to generate
debugging messages containing the entire contents of a BPDU displayed in
readable text for transmitted and received xSTP BPDUs. The debugging can be
activated on a per-port basis and transmit and receive debugging is controlled
independently. Although this command uses the keyword mstp, it displays
debugging output for RSTP and STP protocols as well as the MSTP protocol.
Due to the likely volume of output, these debug messages are best viewed using
the
command. The default terminal monitor filter will select and display these
messages. Alternatively, the messages can be directed to any of the other log
outputs by adding a filter for the MSTP application using the
command:
awplus(config)#
Output 2 In MSTP mode - an MSTP BPDU with 1 MSTI:
