Configures the method used by STP to flush the FDB during a topology change.
| vlan-and-port | Specifies a VLAN and port combination flush method. |
| port-only | Specifies a port flush method. |
The default flush method is vlan-and-port.
For scaled up configurations where there are more than 1000 VLANs and more than 70 ports participating in STP, the number of messages exchanged between STP/FDB/HAL modules can consume a lot of system memory during an STP topology change using the default configuration for flush method. In such situations, setting the flush method to “port-only” can help reduce the system memory consumption.
The following command sets the flush method to port-only:
configure stpd flush-method port-only
