Page 6-39; Modified Example Using a Trunked Link with STP and VLANs. The following

illustration more clearly shows the trunked link configured with two tagged VLANs.

Example of Using a Trunked Link with STP and VLANs

Page 6-43; Multicast Filters.

Insert the following after the ''Multicast Filters'' heading: ''Multicast filters are configured

using the Ethernet format for the multicast address.''

In the Note at the bottom of the page, insert the following at the end of the first sentence:

''...(which corresponds to the Ethernet multicast address range of 01005e-000000 through

01005e-7fffff).''

Page 6-44; Protocol Filter Type. In the bulleted list of filtered protocol types, change NetBIOS to

NetBEUI.

Problem: STP enabled with

2 separate (non-trunked)

links blocks a VLAN link.

Nodes 1 and 2 cannot

communicate because

STP is blocking the link.

Solution: STP enabled with

1 trunked link.

802.1Q VLAN tagging

allows two or more

VLANs to use the

same link.

Nodes 1 and 2 can

communicate because

STP sees the trunk as a

single link and 802.1Q

(tagged) VLANs enable the

use of one (trunked) link for

both VLANs.
