  Enabling or Disabling Rapid Spanning Tree Protocol
Figure 24
Create Layer 2 Service Wizard—QoS Parameters
If the RSTP Enable check box is checked, CTM issues the following command specified for adding a 
drop:
[Configure RSTP; this command is issued once for VLANs]
bridge BG protocol rstp
[Enable RSTP on the selected drop]
Interface {FastEthernetport|GigabitEthernetport}.Port VLAN
Bridge-group BG
The following command is issued when you disable RSTP from a drop:
[Disable RSTP on the selected drop]
Interface {FastEthernetport|GigabitEthernetport}.Port VLAN
Bridge-group BG 
Bridge-group BG spanning-disabled 
[Disable RSTP on the selected drop]
Note
Enabling or disabling RSTP on a port basis is not valid if you configured a bridge group to the main 
Ethernet interface. By default, the CLI disables the dot1Q drop in the card.
If only the RSTP Enable check box is checked, the Spanning Tree Protocol remains disabled on the 
VLAN service drops.
