Figure 6-38. Example of Networked 802.1Q-Compliant Devices with Multiple VLANs on Some Ports
In the paragraph following Figure 6-38, change "Port X-a..." to "Port X1..." Also, change the
last sentence to read "The same applies to ports X2, Y1, and Y5."
Page 6-60:
In the "Note", change "...ports X-A and Y-E..." to "...Ports X2 and Y5..."
In the sentence at the bottom of the table, change "...ports A1 and B5..." to "...X2 and Y5..."
In the paragraph under "Spanning Tree Protocol Operation with VLANS", change the last
two sentences (corrections underlined):
"However, you can use port trunking to prevent STP from unnecessarily blocking ports (and to
improve overall network performance). Refer to'Spanning Tree Operation with 802.1Q VLANs'
on page 6-38."

connected by a trunked link. A topology combining three devices in the same FEC link will not operate
properly. For example:
