Table 40: Platform-Specific and Feature PDs
PD Number Description
General
PD4-1243528711 A switch reboots because a system crash occurs when software is transmitting control
packets on a VLAN while the VLAN is being deleted.
PD4-1084698943,
PD4-977234454
Configuring UPM profiles to include the show port info detail command results
in the show profile history command output showing the status as failed.
BlackDiamond 8800 Series Switch
PD4-449743037 Group entries are not timing out on Multicast VLAN Registration (MVR) and non-MVR
VLANs even though snooping is disabled on the non-MVR VLAN.
BlackDiamond 10800 Series Switch
PD3-68165111 Various memory locations that are part of the forwarding and routing tables are parity
protected on BlackDiamond 10808 switches. The functionality should be turned on so
that faults are detectable.
BlackDiamond 12800 Switch
PD4-482808326 When a configuration is saved as a default.xsf configuration, errors are seen when the
configuration comes up after running the unconfigure switch command.
PD4-1243529244 Running CLI commands on a BlackDiamond 12800 series switch with an MSM-6R
module shows an intermittent delay of 30 to 60 seconds during command execution
PD4-750488331 When a BlackDiamond 12800 series switch with 4,000 BVLANs and 2,000 SVLANs
configured and IGMP snooping disabled, the switch crashes when enabling sharing with
LACP on BVLAN ports. This configuration may also cause an MSM to go into a failed
state.
PD3-205380274 sFlow is not working on ports that are included in BVLANs, SVLANs, and occasionally
vMANs. sFlow can be enabled and configured for ports in BVLANs, SVLANs, and vMANs,
but nothing is sent to the sFlow collector.
BlackDiamond 20800 Series Switch
PD4-969859031 After upgrading from CR21 to CR22 firmware on a BlackDiamond 20808 chassis, the log
fills up with error and warning messages.
PD4-756213981 BlackDiamond 20808 multicast rate-limit supports a minimum 10 Mbps.
PD4-841530197 The install firmware command displays a lot of errors in the log and the HAL CPU
goes to 99% capacity.

PD4-708913560 ExtremeXOS software does not monitor the temperature of I/O modules or the fan speed.
If the temperature sensors on an I/O module exceeds 80 Celsius (C), set both fan trays to
100%. When all temperature sensors on the I/O modules drop below 60 C, set the fan
speed to default (bottom fan tray at 40%, and the top fan tray at 60%). If a temperature
sensor on an I/O module exceeds 90 C, disable the slot and flag it as failed.
