A BlackDiamond 20808 switch with a single MM running ExtremeXOS 12.3.2 software
fails to upgrade during a firmware upgrade process. It also fails during the firmware
downgrade process. You may need to try and install the firmware multiple times.
PD4-803757411 Configuring a meter on a BlackDiamond 20808 switch to limit broadcast or multicast
traffic (rate-limit flood-traffic) is not possible without an HQoS license.
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.
PD4-748173770 Executing run time diagnostics using the run diagnostics normal/extended
command on a GM-40XB module can result in the I/O module locking up after
diagnostics are complete and ExtremeXOS tries to bring the I/O module back online. It is
recommended that you do not execute run time diagnostics on these I/O modules in a
live network.
PD4-728449478 The ucRx: micro controller returns the following error message while running diagnostics:
reset hello error Unrecognized command: hello
feConfig = fffe2848
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.
PD4-756309458 When configuring remote mirroring using a BlackDiamond 20808 switch as the
intermediate or destination switch, the remote mirroring port does not receive IP multicast
traffic if the monitor port of the source switch is tagged. The traffic is dropped in the
transit VLAN.
Workaround: Configure the monitor port of the switch as an untagged port so that IP
multicast traffic will pass through the transit VLAN.
PD4-756213981 BlackDiamond 20808 multicast rate-limit supports a minimum 10 Mbps.
PD4-667561942 The command output for the show fdb hardware command does not include the
blackhole MAC address.
PD4-603229266 A slot reboots when load sharing is disabled and MVR is disabled and re-enabled.
