Summary
User Impact
Resolution
Affected
Platforms
LACP not working with Juniper
EX-4200, show inactive port
channel state. System is sending
oversize (132 bytes) LACP
PDUs.
Potential operator frustration over switch
operations. Inability to interoperate with
Juniper switches.
The LACP process now
sends 128 byte LACP PDUs.
Interoperability with Juniper
switches is verified.
All
Platforms
Stack splits into multiple masters
when MU fails.
Potential operator frustration over switch
operations.
Issue in SDK MAC reset
function resolved such that
connected unit respond to
master within 1 ms. Stacking
stability verified under the
conditions where issue
occurred.
All
Platforms
VLAN name issues in web UI on
modular. Old VLAN name is
retained on web page when
switching to new VLAN.
Potential operator confusion over switch
operations.
The correct VLAN name is
always displayed.
All
Platforms
Discards Occurring After
Firmware Update to current
version 3.1.5.4.
Potential operator confusion over switch
operations.
The wrong counter was
being displayed in the CLI.
The CLI commands “show
statistics port-channel” and
“show statistics <interface>”
are corrected to use the same
counter as SNMP.
All
Platforms
STP topology changes when an
OOB SSH connection is
established
Potential operator frustration over switch
operations.
The SSHD task was starving
other tasks in the system and
causing topology changes.
The SSHD task priority is
now set to the shared time
slice priority.
All
Platforms
ARP broadcast traffic not
forwarded through static/dynamic
10Gb LAGs
Potential operator frustration over switch
operations. Potential network instability.
A field was being utilized in
the LAG hash algorithm that
could result in different hash
indices on different units of a
stack. This field (modid) has
been removed from the hash
selection algorithm.
