What’s New at	This section describes the new features, software enhancements, and
Revision 8.2.3?	corrections implemented at this release.

New Features The following new features have been added at this release.

Software Support for Protocol-based VLANs

Revision 8.2.3 offers support for protocol-based VLANs on the CoreBuilder 6000 system. Protocol-based VLANs allow you to deﬁne VLANs based on the network protocol, including IP, IPX, AppleTalk, XNS, DECnet, X.25 Layer 3, SNA, Banyan VINES, and NetBIOS.

This release allows you to overlap VLANs by supporting multiple protocols per port, multiple subnetworks per port, and the spanning of Layer 3 networks across multiple ports. You can also use an external router to communicate between VLANs.

New menus have been added to the Administration Console menu so that you can administer protocol-based VLANs on the CoreBuilder 6000 system. These menus allow you to:

■Display summary or detailed information on VLANs

■Deﬁne or modify a VLAN deﬁnition

■Delete a VLAN deﬁnition

For more details on VLAN functionality in the CoreBuilder 6000 system, see Appendix C, “VLANs on the CoreBuilder System” and Appendix D, “Administering VLANs.”

Support for Seven RMON Data Groups

Revision 8.2.3 Extended Switching software supports the following RMON data groups:

■Group 1: Statistics — Maintains utilization and error statistics for the monitored segment
