config spanningtree port migrationcheck
Use this command to force the specified port to transmit RST BPDUs. The <port> parameter
specifies the port(s) to be affected. To set the migration check for all ports with a single command,
<all> can be specified. Note that the forceversion parameter for the switch must be set to 802.1w for
this command to work.
Default disable
Format config spanningtree port migrationcheck <port/listofports/all> <enable/disable>
config spanningtree port mode
Use this command to configure the Administrative Switch Port State to a new value for the specified
port. The <port> parameter specifies the port(s) to be affected. To enable or disable all ports with a
single command, <all> can be specified. Note that a maximum of 4095 ports can be enabled.

config spanningtree forceversion
Use this command to select which version of the STP will be used. The <version> can be one of the
following:
• 802.1D - IEEE 802.1D functionality supported: STP BPDUs are transmitted rather than
R(Rapid)STP BPDUs
• 802.1w - IEEE 802.1w functionality supported: RSTP BPDUs are transmitted rather than STP
