ExtremeXOS 12.4.4 Release Notes
104
PD4-728449478 The ucRx: micro controller returns the following error message while running diagnostics:
reset hello error Unrecognized command: hello
feConfig = fffe2848
PD4-551040931 Multicast traffic is dropped after disabling load-share port links using MVR.
PD4-927699591 Running an ExtremeXOS 12.3 image in the Delay Measurement Message (DMM)
originator, and a later version of ExtremeXOS on a BlackDiamond 20808 on the other
end, Y.1731 does not work. The Delay Measurement Reply (DMR) is received by the
originator, but rejected due to an incorrect check in the application.
PD4-978540087,
PD4-978263097
During a malfunction of an adjacent node, excessive DHCP traffic is flooded to the
switch causing watchdog failures and outages.
PD4-749215601 Running the install firmware command generates the following error message:
reading from file /dev/mtd0 failed: Cannot allocate memory
.FAILED: SLOT 18, MM PMON
UPGRADE NOT REQUIRED: SLOT 18, MM Spanky Primary
Error:can't read "pfc": no such variable
PD4-1077149606 A DUT displays errors when a policy file is configured with traffic queues on a VLAN or
vMAN.
PD4-1056438821 If a meter is attached to an egress traffic queue after an ingress traffic queue and an
egress traffic queue association, the meter does not take effect.
Workaround: Configure the aggregate meter for the egress traffic queue first and then
associate it with an ingress traffic queue.
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.
