CLI Reference Guide
To enable fast forwarding mode, use the spanning-tree fast-forwarding
command. When fast forwarding is enabled the interface will be immediately put
into the forwarding state upon linkup without waiting for the timer to expire.
None
Default fast forwarding is automatically derived from an IEEE Std 802.1D-2004
Bridge Detection state machine.
Interface configuration (physical and port-channel interfaces)
Use this command only with interfaces that connect to end stations; otherwise,
an accidental topology loop could cause a data-packet loop and disrupt the
switch and network operations.
During linkup, when an interface, with fast-forwading mode enabled, is moved
directly to the spanning-tree forwarding state, then it is not necessary to wait for
the standard forward-time delay.
This command has two states:
• spanning-tree fast-forwarding -This command enables fast forwarding
state unconditionally on the given port.
• no spanning-tree fast-forwarding -The fast-forwarding state for the given
port is returned to the default settings.
This configuration will take effect on all the spanning-tree modes.
This example shows how to configure the fast-forwarding state at eth3.7.
Verify the settings by entering the show spanning-tree interface command.
