Chapter 2 Cisco Catalyst Blade Switch 3030 Cisco IOS Commands
Description
Clears the spanning-tree counters.
Restarts the protocol migration process.
Enables the BackboneFast feature.
Prevents an interface from sending or receiving bridge
protocol data units (BPDUs).
Puts an interface in the error-disabled state when it
receives a BPDU.
Sets the path cost for spanning-tree calculations.
Enables the extended system ID feature.
Enables the root guard or the loop guard feature for all the
VLANs associated with the selected interface.
Overrides the default link-type setting for rapid
spanning-tree transitions to the forwarding state.
Prevents alternate or root ports from becoming the
designated port because of a failure that leads to a
unidirectional link.
Enters multiple spanning-tree (MST) configuration mode
through which the MST region configuration occurs.
Sets the path cost for MST calculations.
Sets the forward-delay time for all MST instances.
Sets the interval between hello BPDUs sent by root switch
configuration messages.
Sets the interval between messages that the spanning tree
receives from the root switch.
Sets the number of hops in an MST region before the
BPDU is discarded and the information held for an
interface is aged.
Configures an interface priority.
Configures the switch priority for the specified
spanning-tree instance.
Configures the MST root switch priority and timers based
on the network diameter.
Configures an interface priority.
Globally enables the BPDU filtering or the BPDU guard
feature on Port Fast-enabled interfaces or enables the Port
Fast feature on all nontrunking interfaces.
Enables the Port Fast feature on an interface and all its
associated VLANs.
Accelerates the choice of a new root port when a link or
switch fails or when the spanning tree reconfigures itself.
Configures spanning tree on a per-VLAN basis.
