PD4-756263261 The show fabric command in an ExtremeXOS environment shows the fabric
information is XFM-2.
PD4-728354005 On a BlackDiamond 20808 switch, running the show tech-support command when I/
O modules or fabric slots are in the process of booting, or are otherwise not operational,
may cause sys-health-check output to display fabric link faults, when there are
actually none. This is a transient state. Once the modules are operational, only actual
fabric link faults are displayed in the command output.
PD4-603229266 A slot reboots when load sharing is disabled and MVR is disabled and re-enabled.
PD4-587169451 Running the install firmware command may generate numerous error messages in
the Event Management System (EMS) logs. These messages do not impact system
performance.

Summit Family Switches
PD4-1545964372 On a Summit X480 switch, the log message Setting hwclock time to system
time, and broadcasting time is frequently displayed.
PD4-749682632 You cannot run the configure port auto on command on XGM2-2bt ports.
PD3-127401831 On a Summit X250e platform with 128 VRRP instances that are advertised for 100
milliseconds, the feature "don't preempt" is not working properly.
PD4-427423116 When a dot1x client is authenticated at multiple VLANs, the output of the show
netlogin port command shows the client is sometimes authenticated at the local
server and other times at a RADIUS server.
Note: This occurs when dot1x and MAC authentication are enabled on the port.
PD4-1101069206 When configuring 2,000 VPWS instances, only 1,023 VPWS instances are created.
PD4-448681226 The show l2stats command does not count ARP packets to the CPU, even though
the packet goes to the CPU.
PD4-489142320 One Gigabit ports set to auto on flap twice during a switch reboot.
PD4-489359602 Conflicting Link Fault Signal (LFS) alarms are shown when disabling local ports.
PD4-274249122 If a Summit switch populated with an XGM2-2bt module is rebooted, a false link up is
seen on 10G links connected to the XGM2-2bt ports approximately 30 to 50 seconds
before the switch has fully booted.
