Known Issues
The following are all the outstanding known issues from previous releases. The issues listed here may have been discovered on
any of the switches listed on the title page.
Release 5.1.1.7
Summary User Impact Workaround
PC8100 - SCP or SFTP
file transfers to FreeBSD
and Mac causes switch to
crash and reboot.
SCP or SFTP file transfer from PowerConnect
8100 switches to a FreeBSD or Mac client/server
causes the switch to crash and reboot. Eventually
connectivity comes back after a few seconds, but
the connectivity loss is long enough to cause
iSCSI connections to drop.
Workaround: None.
Fix is under review and it will be available in
the next maintenance release.
8024 - Routing issue,
null address in ARP table
after VLAN
manipulation
Some null mac address (0000.0000.0000) present
in PC8024 ARP table. This happens after vlan
manipulation (like create, delete, define IP
address, add and remove on trunk port).Issue
occurs randomly and not immediately (take
between 30min and 1h between vlan
manipulation and routing issue)
Workaround: Reloading the switch resolves the
issue temporally (till next vlan
reconfiguration). Add static entry in ARP table
resolves the issue.
Fix is under review and it will be available in
the next maintenance release.
PCM6220 v5.0.1.3
switch crashes every 30-
40days while SNMP
monitored
PCM6220 Switch crashes every 30 to 40 days
when SNMP monitoring with cacti version 0.8.8a
Workaround: None.
Fix is under review and it will be available in
the next maintenance release.
M6348 Stack - interface
in static LAG goes into
inactive state while
physical interface is up
Due to a race condition, while the lag member
links flap, the lag member that linked up may be
put into standby, when at the same moment any
existing members in the lag goes down.
Workaround: None.
Fix is under review and it will be available in
the next maintenance release.

Summary
User Impact
Workaround
Molex QSPF DAC Cable
with part number
111040-1104 does not
comply with QSFP
specification SFF-8436.
These cables do not
support 'voltage'
diagnostics.
Voltage is displayed as 0.00 instead of "N/A" for
this diagnostic parameter.
Ignore the voltage displayed field for this part
or use a SFF-8436 compliant cable.
Show AAA IAS-USERS
<Username> Command
Missing
The “show aaa ias-users [username]” command
seems to have been deprecated even though it
still exists in the CLI guide.
The same information can be seen within the
running configuration of the switch with the
“show running-config” command.
External CDP/ISDP
traffic occasionally
forwarded onto internal
ports
Occasionally external CDP/ISDP packets are
being forwarded to the internal ports. This
results in confusing information from the blade
server point of view as multiple directly
connected neighbors appear to be seen.
None.
Multicast sources that
cease sending multicast
are timed out and
removed from the
multicast forwarding
cache after 150 seconds
If an intermittent multicast source that has been
aged out of the multicast forwarding cache
begins sending again before the corresponding
S,G entry has timed out at the RP (185 seconds
per RFC 4601), any *,G entries (joined hosts)
may take up to one IGMP Query interval to begin
receiving the multicast stream.
The default IGMP query interval is 125
seconds. In practice, this situation is very
unlikely to occur as a multicast source that fails
to send even one packet for 150 seconds is
unlikely to start sending packets before the S,G
entry at the RP times out.
