Cajun P550/P220 Switch Operation Guide 

12-1 

This chapter and its procedures are common to both Layer 2 and Layer 3 configuration. 
Included in this chapter:

❒ VLAN Operation

❒ Creating and Implementing VLANs

❒ Using Spanning Tree Setup and Monitoring

❒ Using Hunt Groups to Aggregate Bandwidth between Switches

VLAN operation is based on three sets of rules:

❒ Ingress Rules

❒ Forwarding Rules

❒ Egress Rules

Every frame received by the switch is classified to one VLAN. There are two ways in 
which frames are classified to VLANs:

❒ Untagged frames are classified to the VLAN associated with the port on which the 

frame is received (Port-based VLANs).

❒ Tagged frames are classified to the VLAN identified by the VLAN tag in the tag 

header of the frame.
