• Workarounds:
○ Before
upgrading to the new code, it is necessary to ensure password control is disabled.
Execute the “undo password-control enable” and then save this configuration file as a backup
in case you need to downgrade the software again. If it is later necessary to downgrade to
earlier software, force the switch to use this backup configuration file by executing a ”startup
saved-configuration (filename)” command before rebooting to the old code. Then, after the
code has been downgraded, the device can be logged in from the console or by Telnet, but not
SSH. The SSH authentication details will need to be reset.
○ If no backup configuration has been saved but it is still possible to access the device
management via some method while running the old
code (e.g. Console, Telnet or SSH), then
you can redefine all the device management passwords as required.
○ If after a downgrade it is impossible to login to the device via any method, then there are two
ways to recover the switch:
− From the BOOT menu, set the new
code to run again and reboot the device. Disable Telnet
authentication:
User-interface vty 0 4
Authentication mode none
Then save the configuration and downgrade the code again, login via Telnet and reset all
the passwords as required.
− From the BOOT menu. On boot-up, use Ctrl+B to enter the Boot menu and then force the
unit to use the factory default configuration (bypassing the user configuration). The unit will
then need to be fully reconfigured.

• First found-in version: CMW520-R6701
• Description: Reboot an IRF fabric comprised of four switches. If the switches are not synchronously
rebooted, the IRF fabric may split.
• Workaround: Make sure the switches have similar card configurations, can back up each other,
and are rebooted at the same time. If the IRF fabric splits, reboot the smallest IRF system so the
switches can join the system to re-form a 4-chassis fabric.
LSD62272
• First found-in version: CMW520-R6626
• Description: RRPP fails to operate when the RRPP control VLAN ID is identical with the sub interface
VLAN ID.
• Workaround: Do not configure the same VLAN ID for them.
LSD62435
• First found-in version: CMW520-R6626
• Description: A sub interface fails to forward traffic to another chassis when its VLAN ID is identical
with the MAD VLAN ID.
• Workaround: Do not configure the same VLAN ID for them.
