The parameters you would normally set when configuring STP are applicable to RSTP. Before you configure RSTP see the STP parameters sections for descriptions of the bridge parameters, the error disable timeout parameter, and the port channel path cost parameter.
There is one parameter that can be configured in RSTP that is not available in STP; the transmit hold count. This parameter configures the BPDU burst size by specifying the maximum number of BPDUs transmitted per second for before pausing for 1 second. The range is 1 through 10 while the default is 6. See Configuring RSTP for the procedures to configure this parameter.
The edge port and auto edge features can be enabled in RSTP as well. See the section Edge port and automatic edge detection and the section Enabling and configuring RSTP on an interface for descriptions of these features and how they are configured.
