Forward Delay Before Ports Transition to Forwarding State
The forwarding delay timer specifies the length of time a spanning-tree protocol bridge
port remains in the listening and learning states before transitioning to the forwarding
state. Setting the interval too short could cause unnecessary spanning-tree reconvergence.
Before changing this parameter, you should have a thorough understanding of
spanning-tree protocols.

Spanning-Tree Instance Interface
STP and RSTP are limited to a single instance on any physical interface. Use the interface
statement to configure which interfaces participate in the STP or RSTP instance.
MSTP supports multiple instances on a single physical interface. Use the interface
statement to configure which logical interfaces participate in MSTP.
For VSTP, interfaces can be configured at the global level or at the VLAN level. Interfaces
configured at the global VSTP level will be enabled for all the configured VLANs. If an
interface is configured at both the global and VLAN levels, the configuration at the VLAN
level overrides the global configuration.
