Using VLANs, Spanning Tree, Hunt Groups, and VTP Snooping
Assigning Ports to VLANs
Refer to “ Configuring Switch Port Parameters ,” in Chapter 5 for
instructions on assigning ports to VLANs.
CAUTION
Before changing the VLAN that a port is assigned to, you must
remove the port from the hunt group that the port is assigned to. Do
not attempt to change the VLAN and remove the port from the hunt
group simultaneously. If you do, the switch assigns all ports in the
hunt group to the new VLAN.

Spanning Tree Protocol Implementation
This section introduces Spanning Tree Protocol, explains how it
operates, and provides configuration procedures.
What is
Spanning Tree
Protocol
The Spanning Tree Protocol is a layer 2 or bridging protocol that
provides path redundancy while preventing undesirable loops in the
bridged network. The Spanning Tree Protocol algorithm creates a
single path through the network by ensuring that if more than one
path exists between two parts of a network, only one of these paths
is used, while the others are blocked.
* Note: The Spanning Tree Protocol (STP) Port Priority range has
been changed. The values are now 1 to 15. If you
changed the default range in an earlier release, you
should verify that the priority is within the allowed
range.
For more detailed information about the Spanning Tree Protocol,
refer to the IEEE 802.1D standard for Media Access Control (MAC)
bridges.
