Summary
User Impact
Workaround
OpenManage displays
incorrect session timeout
duration when using
secure HTTP
After the browser session timeout (default 10
minutes), OpenManage displays incorrect session
timeout duration in the message "Your session
had been inactive for more than 240 minutes",
which is the actual setting for telnet and ssh.
However, the actual timeout occurs after the
default period of 10 minutes, so the GUI message
is incorrect.
Disregard the time in this GUI message.
Cannot disable the SFS
"allow-downgrade"
feature
Even with SFS allow-downgrade disabled, the
master will still push the older firmware to a
stack member running a newer version of code.
Always make sure the master has the wanted
version loaded.
Console port locks up
when awaiting telnet
Radius response
Radius authenticated Telnet login attempt when
Radius daemon stopped, causes console port to
be temporarily blocked until Radius timeout
expires.
Wait for timeout or ensure Radius server is
reachable.
Flowcontrol is in inactive
state when connected to
Partner(Randall) with
combo ports.
Flowcontrol gets automatically disabled and if
the ports have a need for Flowcontrol, there will
be no pause frames sent.
Re-enable Flowcontrol on Randall switch.
7048R replacement
power supplies reported
as incompatible
Although the power supplies part number is the
same, the 7048R reports it as incompatible and
thus the error message is incorrect. The power
supplies still works correctly.
Ignore the error message, since there are no
functional issues with this power supply.
PowerConnect 7048P :
poe_lldp.c(1741) 23137
%% Failed to get pairs
control
After a long period of time and numerous IP
phones connected and with at least 5 switches
connected as a stack, PoE error messages start
filling the logs.
Maximum supported IP phones at this time is
64.
SNMP showing packets
discarded while cli
doesn't show the same.
SNMP monitoring tool is pulling stats from
M8024 and shows very high discard receive rate
but switch doesn't say the same.
None.
PC M6220 Running
configuration altered
after removal of stacking
master, 4.1.0.19, 4.1.1.7
When master member was removed from and
reinserted into an M1000e enclosure, some of the
configuration was missing from running-config.
Always write the config before removing
master.
Stacked m8024-k or
8024/8024F switches
running code that
supports Ethernet
stacking should not be
downgraded to older
code that doesn’t support
Ethernet stacking.
Customers downgrading a switch stack to a
version of code that does not support stacking are
advised to:
1) Break apart the stack into individual units
2) Clearing the saved config on each unit
3) Renumber each unit to unit 1 using the switch
X renumber 1 command
Failure to follow these instructions may cause
units to crash when booted into the 4.1
firmware. To recover the switch, attach a serial
cable and enter the boot menu (press 2 - Start
Boot Menu at the prompt). From the boot
menu, select 10 - Restore configuration to
factory defaults, and then select 1 - Start
operational code
PC7048P, in a stack will
error out when all
rebooted at the same
time.
The stack will stop passing traffic if all switches
in the stack are rebooted simultaneously.
If this situation happens, it is recommended
that each power switch be rebooted in sequence
with a four to five minute interval between
each reboot.
Jumbo frames cause
transmit errors on port
channel
Transmit Errors is seen on port channel, but not
on the members of the port channel. Counters
remain inaccurate.
None – Inaccurate transmit errors do not cause
functional issues.
