Bug Fixes:

  • Switch randomly restored to factory default settings after reboot.
  • Switch management no longer respond if the default gateway becomes unreachable

Known Issues:

  • If the network is set to DHCP mode on version 10.0.1, and then is upgraded to 10.0.2, the network interface protocol mode changes to ‘none’ and its IP is set to ‘0.0.0.0.’, and DHCP mode is enabled on the management VLAN instead. 
  • Auto-install is not allowed to apply a configuration file if the startup-config file contains commands related to the network interface, which is not supported on 10.0.2. 
  • M4100 does not support IPv6 management on the management VLAN.
  • If a protected port is configured, routing mode disabled on the VLAN with the protected port.
  • When M4100-D12G-POE+ / GSM5212P is powered up through PD ports 1 and 2, and ports 3 - 12 are used as PSE ports, the maximum PoE power budget delivered by ports 3 - 12 will be only 25W. In order for ports 3 - 12 to deliver the power, follow either method A or B below:
    • Method A.  Configure the power limit type as ‘user-defined’ and configure the maximum power as 25W. Example

      (GSM5212P) (Config)#poe power limit user-defined 25000

      Or, 

      Method B.  Configure the power limit type as ‘class-based’ and disable the high power mode. Example:

      (GSM5212P) (Config)#poe power limit class-based

      (GSM5212P) (Config)#interface 0/3

      (GSM5212P) (Interface 0/3)#no poe high-power

      (GSM5212P) (Interface 0/3)#exit

  • If the switch model is a PoE switch, note that the new release comes with a new PoE controller firmware that required a few extra minutes to perform the PoE firmware update. During this time, do not power off the switch. If the update fails, unplug all cables from the ports and power cycle the switch.
  • Do not use a USB flash port to perform the firmware update if the switch model is a PoE model.
