Summary
User Impact
Workaround
QSFP Base CR4 with
copper DAC cable
lengths greater than 3
meters will not work on
PC8100 switches
When using the DAC copper cables with QSFP
CR4s (which are rarely used) and cable more
than 3 meters, the switch may not even detect
this device and so link up never happens. Only
the following cables are recommended with these
CR4 QSFPs:
111040-1104 – 1m Passive Copper Assembly
111040-1204 – 3m Passive Copper Assembly
None
On PC8100 switches,
sharp decrease in 6to4
tunnel traffic is observed
when ipv4 static route is
deleted and added back
to the switch.
This is a corner case issue requiring many steps
to get to this state but if the state is reached, the
user will see less through-put on the tunnel.
Stop traffic for a minute or two so that the stale
entry in the Linux stack is cleared.
Failure log messages
may show up on console
on doing a SNMP walk
on root node.
There is no effect besides the annoyance of these
messages while doing an SNMP walk.
None
Speed is not applied to
combo (copper) ports
after saving and
reloading the DUT
(8024/8024F).
Since these configuration variables exist for both
copper and fiber modes (combo ports), the speed
and duplex are not saved since the port assumes
that it will only save fiber parameters and thus
the customer will notice that the port auto-
negotiates after reload instead of goes to a static
speed or duplex.
Always reconfigure the speed on copper combo
ports after reboots on the 8024/8024F.
SFP+ module is still
detected in running-
config after clear
config on PC8100 with
QSFP to 4x10G
The information that will be stored in the
running-config specific to the 4x10G port (QSFP
to 4x10G) will not be cleared after the clear
config command.
User can negate these commands manually
after a clear config.
Status is not shown after
the image upload using
HTTP through IPv4
HTTPS session
The user may not be aware that the download has
completed when using the GUI.
User must refresh screen or go to version
screen for indication that the download has
completed.
Console logs/syslogs are
not generated if we
disable LAG local
preference.
This will only be seen when disabling the local
LAG config and will not affect the system.
None
The following unwanted
logs may come up on
console after running the
“clear config” command.
1) dot1s helper
logs
2) snooping logs
3) “ATP RX:
Failed to alloc”
logs
There is no effect to the switch or user, just
unwanted log messages on console.
None
