Configuring all xSTP on DCB interface ports
24
Enabling port fast (STP and PVST)
Use this procedure to enable port fast on an interface to allow the interface to quickly transition to
the forwarding state. Port fast immediately puts the interface into the forwarding state without
having to wait for the standard forward time. This procedure applies to STP and PVST only.
NOTE
If you enable the portfast bpdu-guard option on an interface and the interface receives a BPDU, the
software disables the interface and puts the interface in the ERR_DISABLE state.
Enabling port fast on ports can cause temporary bridging loops, in both trunking and non-trunking
mode.
Use the edge port feature for MSTP, RSTP, and Rapid PVST (refer to “Enabling a port (interface) as
an edge port” on page 359).
To enable port fast on the DCB interface for STP, perform the following steps.
1. Issue the RPC to configure the interface node in the
urn:brocade.com:mgmt:brocade-interface namespace.
2. Under the node, include the , ,
, , or node element.
3. Under the , , ,
, or node element, include the following elements.
a. In the element, specify the interface name in [rbridge-id/]slot/port format or
port-channel number.
b. In the element, include the delete operation in the element tag to enable the
port.
c. Include the node element, which resides in the
urn:brocade.com:mgmt:brocade-xstp namespace.
4. Under the node, include the node element.
5. Under the node, include the following leaf elements.
a. Include the empty element to enable basic port fast functionality.
b. Include the empty element to guard the port against the reception of
BPDUs.
c. Include the empty element to set the port fast BPDU filter for the port.
