PD4-1241897589,
PD4-1232462236
A hardware error may occur on a BlackDiamond 12800 series switch resulting in a
misread on the backplane SerDes FPGAs. This misread is interpreted by the system-
health-check as an error, which in turn may cause an I/O module or MSM to be taken
offline.
PD4-751999119 When configuring HQoS, traffic goes to the correct traffic queue but is not limited by the
meter threshold rate.
PD4-979176301,
PD4-832095668
The ACL match condition ports ingress <port-no> causes incoming packets to be
forwarded to all ports in a VLAN as per the VLAN tag for incoming packets, even though
the ingress port is not part of that VLAN.
BlackDiamond 20808 Switch
PD4-1345342342 A multicast stream with a TTL value 255 is not forwarded, but a multicast stream with a
TTL value 2-254 is forwarded correctly.
PD4-1306224691 Multicast traffic is not processed on untagged vMAN ports correctly. For example,
• Untagged mulitcast packets are dropped.
• If a multicast packet is tagged and matches any existing vMAN tag, the packet is
flooded on that vMAN with 8100 ethertype.
PD4-826996622 When a power fan controller stops communicating with a fan tray, the state of the fan
tray is displayed as "INVALID_S," which is not a defined state.
PD4-1034364517,
PD4-913402141
Process XMLD crashes if multiple "OpenSession" XML requests are sent continuously.
PD4-1056306393 Packets received on an "ESRP host attach" port are dropped on a BlackDiamond 20804
switch when the switch is in ESRP slave mode.
PD4-1027880666 Using two BlackDiamond 20800 series switches acting as a VRRP master and a VRRP
backup in an EAPS ring topology, the system crashes with the following error:
epc : c07a2668 kioSendFdb+0x184/0x0 [exvlan]
PD4-923239211 LACP, round robin, and address-based L2 and L3 algorithms are not supported on a
BlackDiamond 20800 series switch and should be blocked in the CLI.
PD4-963878819 When a BlackDiamond 20808 series switch runs an MM failover, or a failover is
occurring due to a process failure, too many SNMP traps are generated.
PD4-885510528 Multiport FDB support is not available on a BlackDiamond 20800 series switch in
ExtremeXOS software.
PD4-946603143,
PD4-872419991
After running the run diagnostics extended command on slot1 of a
BlackDiamond 20808 switch, slowpath traffic is no longer forwarded to the CPU on slot
1.
PD4-964664834 The following logs are displayed in the master MM when the backup MM is becoming
active and the master MM tries to checkpoint the PVLAN data:
<Erro:DM.Error> MM-B: hal: cannot create msg DM_MSG_CHKPT_DATA
c10b 235c 0x10bbcd00
<Crit:DM.Critical> MM-B: hal Cannot create msg DM_MSG_CHKPT_DATA
of size 9052 (too big)
PD4-973283131 The sys-health-check fails to send data to an inactive port. The sys-health-check packets
are dropped because the buffer is full and flow-control is on.
PD4-978263097 During a malfunction of an adjacent node, excessive DHCP traffic is flooded to the
switch causing watchdog failures and outages.
PD4-964136923 The following error message is displayed when checkpointing IPv4 ECMP fails because
of a data allocation error:
<Crit:DM.Critical> MM-B: hal Cannot create msg DM_MSG_CHKPT_DATA
of size 14164 (too big)
