Bug Fixes:

  1. After LAG logical interface is disabled, you can still enable individual port members without admin enabling the LAG interface first.
  2. Traffic loss when firmware upgrade/reboot on M4300 stack
  3. PTP Master clock election fails after adding new device to Dante Network
  4. Multiple PTP master clocks show up in Dante network when IGMPv3 is in use.
  5. Need to add port packet transmit receive error in show interface counter
  6. The temperature threshold set incorrectly in all XSM43xx models
  7. Need to add 'show poe' to tech-support file
  8. Unable to stack M4300-96x switches via Cisco QSFP-40G-SR-BD modules
  9. Rx discard counter increase on M4300 stack ports
  10. Show wrong speed rate when executes the command "show interface counter"
  11. Customer having problems passing their specific Multicast addresses using the latest firmware 12.0.7.12 but working on older firmware.
  12. New master in a stack changes the ports to detach state after master failover
  13. From this release onward, the port list for known multicast addresses will be shown with word “ALL” instead of showing every port in the switch
  14. Tech-support file includes output of “show igmpsnooping ssm entries/groups” command.

Known Issues:

  1. When a 40G port on APM402XL is expanded into 4 10G ports, these 10G ports cannot be configured as stacking port due to hardware limitation
  2. The 40G port can be expanded into four 10G ports via new ‘hardware profile portmode’ command, but this command will not retain across stack failover from stack master to standby unit.
  3. User could pre-configure a APM402XL before the module is inserted the slot. And most of port configuration can be applied except the port expander command, ‘hardware profile portmode’ will fail. 
  4. The port LED on APM402XL module is not blinking when there is line activity and the 40G port is operating in four 10G ports mode. (HW limit)
  5. Stacking port mode does not survive hot plug-out and plug-in. One or more ports of an APM can be configured in Stacking mode. Once reloaded with this APM inserted, those ports would still operate in stacking mode. However, during run time, if the same APM is plugged out and plugged back in, the configured stack ports will be restored back to Ethernet mode. User would need to reconfigure them manually for stacking mode after hot insertion. 
  6. Hot plug-in of any APM module won’t work if M4300-96X is booted without any APM pre-installed and with factory default settings. Install at least one APM module before booting up the switch.
  7. When APM402XL is operating in four 10G port mode, and connects these 10G ports are connected with a DAC fan-out cable, the link #1 of DAC fan-out cable will show up as port 3 in switch’s configuration and physical link #3 will show up as port 1 inside the switch’s configuration. This will be fixed in the upcoming maintenance release.
  8. M4300-96X copper port doesn’t link up at 2.5Gbps when it is connected to WAC740’s 2.5G port, it works only at 1Gbps. This will be fixed in the upcoming maintenance release.
