PD4-1058161045 Rate shaping is not occurring as per configured limits on an ACL meter.
Workaround:
• Configure the committed rate for the meters associated with CoS levels in bandwidth
mode.
• The peak rate for an aggregate meter should be greater than the sum of the committed
rates of CoS level meters.
PD4-1096903835,
PD4-1096903835
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]
PD4-1083445001 Packets received on an "ESRP host attach" port are dropped on a BlackDiamond 20804
switch when the switch is in ESRP slave mode. BlackDiamond 20804 switch drops EAPS
PDUs when IP ARP replies are ingressing the switch.
PD4-800314011 The clear fdb command removes an FDB entry in hardware but the entry remains in
software. Running the clear fdb command a second time clears the FDB entries in
both the hardware and software.
PD4-820920473,
PD4-789754441
A BlackDiamond 20808 process crash occurs when running the debug hal show
device packet-processor printXCounters command with an invalid parameter
ID.
PD4-748173770 Executing runtime diagnostics using the run diagnostics normal/extended
command on a GM-40XB or GM-40XA 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 runtime diagnostics on these I/O modules in a
live network.
PD4-853995054 The process upgrade_fw crashes with signal 11 when downgrading a BlackDiamond
20808 switch.
PD4-865667843 PFC uC fails to turn off the power supply once it detects a failed power supply. The bad
power supply takes 2.5 minutes to boot up. The PFC uC reads the I/O PIN associated
with the PSU alarm PIN and fails the PSU, but it does not power down the bad PSU.
PD4-918412390,
PD4-890754421
L3 traffic is not distributed among LAG ports if a static FDB is configured on the LAG
port of a BlackDiamond 20808 switch.
PD4-751294438 A PVLAN subscriber VLAN side device cannot reach a network VLAN side device.
PD4-807083163 Running an MM failover multiple times on a BlackDiamond 20808 switch may result in
IPv4 packets being forwarded in software.
PD4-815641157,
PD4-779588691
An FDB process crash occurs after enabling an LACP LAG.
PD4-826609208,
PD4-805055301
When a single port is configured for WAN PHY, the show configuration vlan or
show configuration commands display all ports having a WAN PHY configuration.
PD4-870848448,
PD4-852419538
The link on a 10GE port remains active when the Tx fiber is removed from a
BlackDiamond 20808 switch while the Rx fiber remains connected.
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.
PD4-872419991 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.
PD4-798727801 A PSU is used in slot 4 and 5 in a BlackDiamond 20808 chassis, but ExtremeXOS
software or the MM identifies the PSU in slot 4 only as “power failed." The PSU in slot 5
is operational based on an LED inspection, but ExtremeXOS does not recognize the PSU.
