[4210-Ethernet1/0/1] undo stp compliance 

To make a MSTP-enabled switch compatible with STP/RSTP, MSTP provides the 
following three operation modes:

■

STP-compatible mode, where the ports of a switch send STP BPDUs to 
neighboring devices. If STP-enabled switches exist in a switched network, you 
can use the stp mode stp command to configure an MSTP-enabled switch to 
operate in STP-compatible mode.

■

RSTP-compatible mode, where the ports of a switch send RSTP BPDUs to 
neighboring devices. If RSTP-enabled switches exist in a switched network, you 
can use the stp mode rstp command to configure an MSTP-enabled switch to 
operate in RSTP-compatible mode.

■

MSTP mode, where the ports of a switch send MSTP BPDUs or STP BPDUs (if 
the switch is connected to STP-enabled switches) to neighboring devices. In 
this case, the switch is MSTP-capable.

By default, a port recognizes 
and sends MSTP packets in 
the automatic mode. That is, 
it determines the format of 
packets to be sent according 
to the format of the packets 
received.
