New Features and Enhancements:
- Reduce M4300-8X8F fan noise during system reboot cycle
- Condense outputs for two show stack commands to show only ports that are configured in the stacking port mode
- Change Ethernet MTU default to jumbo frame size 9216
- Enhance ‘show ip igmp groups vlan 1 detail’ output by adding the mac address format of each multicast IP address detected in the switch
- Change Tech-Support file default name to include model and firmware version such that it is easier to identify which TS file is for which model and version
- Change to not having mrouter mode got enabled automatically when IGMP querier is detected
Bug Fixes:
- Resolved 403 error with IE11 browser when accessing web GUI online help
- Corrected the rate value in 'show stack-port counter' display
- Resolved ‘snmpget - No Such Instance currently exists at this OID’ error when using snmpget to read OID, .1.0.8802.1.1.2.1.1.7.1.1 (lldpConfigManAddrPortsTxEnable)
- Correct error that not all the packet with known IPv4 multicast address are flooded to all ports (e.g. EIGRP)
Known Issues:
- 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
- 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.
- 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.
- 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)
- 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.
- 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.
- 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.
- 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.
