Release Notes for ExtremeWare v6.2.1
• Diagnostics: A number of enhancements have been made in ExtremeWare diagnostics. These include
improved speed (decreased boot time) for the Fastpost diagnostic, improved error output, and
adding some minor packet memory testing to the Normal level diagnostic.
• Dynamic Packet Memory defect detection and removal (BlackDiamond): This new feature enables
the immediate detection and elimination of packet checksum errors from BlackDiamond I/O blades,
through a combination of packet memory (PM) scanning and memory remapping. If system health
checking with auto-recovery is enabled on the BlackDiamond, packet memory scanning will be
triggered automatically upon three consecutive occurrences of checksum errors, including internal
and external MAC port parity errors, EDP checksum errors, and CPU packet or diagnostic packet
checksum errors. If packet memory defects are detected, the board will be automatically taken
offline, put into a diagnostic mode, the defective buffers remapped, and then returned to operational
status.
See Chapter 12, “Status Monitoring and Statistics” in the ExtremeWare Software Command Reference
Guide for a detailed description of the command to configure the system health checker for
auto-recovery.
PM scanning can also be invoked from the command line using the
run diagnostics command. If
packet memory defects are detected, this command will take the board offline, remap the defective
buffers, and then returned the board to operational status.
See Appendix B in the ExtremeWare Software Command Reference Guide for a detailed description of
this command.
PM defect detection and mapping is currently supported on the G8Xi, G12SXi, F48Ti, and G8Ti
modules. It is not currently supported on the MSM64i.
• Disable BlackDiamond and Alpine slots: New commands allow you to disable and enable slots on an
Alpine or BlackDiamond switch, leaving a disabled slot in a power down state. A slot can be
disabled with or without a blade inserted: a blade that is inserted into a disable slot will stay in the
power down state.
See Chapter 4 in the ExtremeWare Software Command Reference Guide for a detailed description of these
commands.
• EAPS enhancements: The EAPS functionality has been enhanced in two ways in ExtremeWare 6.2.1:
— EAPS-Transit switches and ESRP-aware switches now use different hardware queues for
broadcasting Control Messages and for forwarding generic broadcast traffic. This ensures that
control messages will not get lost in the event of a broadcast storm.
— Sanity checking is now done to ensure that the configuration of an EAPS domain, and the
configuration of the Control VLAN, are correct before attempting to start the EAPS domain
running. If there are problems with the configuration, warning messages will be displayed and
the domain will not be started.
• Extreme Standby Router Protocol (ESRP) enhancements:
— The Secondary MAC registration feature is a new search mechanism introduced to optimize
performance of MAC address lookups for ESRP and VRRP solutions.
— Domain Member and Sub-VLAN support on Host Attached ports: This feature provides scaling
and redundancy up to 3000 VLANs on HA. With the introduction of the Summit Px1, this feature
allows users to connect redundant Px1s on our existing ESRP topology. Earlier restrictions that
required HA ports and sub-VLANs to be mutually exclusive have been lifted.
— Two new ESRP election algorithms are provided to ensure no fail back if the original Master
recovers.
Chapter 14 in the ExtremeWare Software Command Reference Guide for a detailed description of the
command for configuring the ESRP election algorithm.
