ExtremeXOS 12.4.2 Release Notes

PD4-748388236 Egress rate shaping does not work after running the save and reboot commands if an
egress port is not specified. Configured egress rate-shaping does not work on a newly
inserted I/O module if an egress port is not specified.
Workaround: Unconfigure the ACL and re-apply the same ACL.
PD4-715473099 The multicast traffic receive rate for 10,000 multicast groups takes an excessive amount
of processing time.
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.

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.
