Summit switches and BlackDiamond 6800 switch modules that use naming conventions
ending with an “i” have additional capabilities that are documented throughout this
User Guide. For the most current list of products supporting the “i” chipset, consult
your Release Notes.
Unless otherwise specified, a feature requiring the “i” chipset requires the use of the
BlackDiamond MSM64i and an “i” chipset-based I/O module, such as the G8Xi.

The following list summarizes the feature areas specific to the “i” chipset products:
• QoS and Access Policies – Complete use of IP access lists (products without the “i”
chipset are capable of a subset of this functionality); support for IP DiffServ; and
support for eight QoS queues per port, instead of four.
• Bridging/Switching – Support for jumbo frames; support for address- and
round-robin-based load-sharing algorithms; ports belonging to a load-sharing group
do not need to be contiguous.
• Routing – Wire-speed IPX routing
• BGP-4 – Requires the use of the “i” chipset, but requires only the MSM64i on the
BlackDiamond.
• Server Load Balancing – Requires the use of the “i” chipset.
• Web cache redirection – Requires the use of the “i” chipset.
• ESRP – No port blocking restrictions, use of the additional tracking ESRP feature.
• Load sharing – No contiguous port restrictions.
