Figure 1-1. Tagging Schemes
OpenTrunk technology has the following features:
❒
Switch supports frame encapsulation:
•
Identifies frame VLAN via tag
•
Associates frame priority
❒
Switch supports multiple tagging formats:
•
IEEE pre-standard format based on 802.1Q draft document
•
A major vendor’s multi-layer tagging scheme
•
3Com® VLAN Tag and PACE priority signalling
❒
Switch supports translation to and from any format. A packet can enter the switch
with a 3Com SuperStack II VLAN tag and exit the switch as a multi-layer tagged
packet (Figure 1-2).
