Known Issues - Dell Networking 7048 Release Note

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 5.1.0.1
Summary User Impact
Molex QSPF DAC Cable Voltage is displayed as 0.00 instead of "N/A" for
with part number this diagnostic parameter.
111040-1104 does not
comply with QSFP
specification SFF-8436.
These cables do not
support 'voltage'
diagnostics.
Show AAA IAS-USERS
The "show aaa ias-users [username]" command
<Username> Command
seems to have been deprecated even though it

still exists in the CLI guide.
PC70xx - Email alerts PowerConnect 7048 switches that are setup to
fail when logging level is send email alerts for log messages at the default
default level can produce the following log message:
Email Send Failed! No of Email sends Failed So

Web UI issues with pre-
The Web UI seems to be saving the configuration

reloaded the configuration for these ports are no
longer correct.
External CDP/ISDP Occasionally external CDP/ISDP packets are
traffic occasionally being forwarded to the internal ports. This
forwarded onto internal results in confusing information from the blade
ports server point of view as multiple directly
connected neighbors appear to be seen.
Multicast sources that If an intermittent multicast source that has been
cease sending multicast aged out of the multicast forwarding cache
are timed out and begins sending again before the corresponding
removed from the S,G entry has timed out at the RP (185 seconds
multicast forwarding per RFC 4601), any *,G entries (joined hosts)
cache after 150 seconds may take up to one IGMP Query interval to begin
receiving the multicast stream.
Release 5.0.1.3
Summary User Impact
ipv6 ping is not reliably IPv6 functionality requiring Neighbor Discovery
will not work

58
Workaround
Ignore the voltage displayed field for this part
or use a SFF-8436 compliant cable.
The same information can be seen within the
running configuration of the switch with the
"show running-config" command.
Change the email logging level to something
other than default, i.e. informational alerts. The
switch will then send the alerts with no issues.
Use the CLI if possible.
None.
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.
Workaround
None
