PowerConnect 3424/3448 Release Notes • Spanning Tree Root Guard • Link Layer Discovery Protocol • HTTP/S Upload / Download of Configuration Files • HTTP/S Upload of Software Image Issues resolved The following is a list of issues resolved in the current firmware release. Title Management Station Loses Communication to Stack after Master Unit Failure. Configuration file with PVLAN cannot be copied to startup. Native VLAN display. Display of configured LACP Channels. WBI Stacking Port Information Description When a management station is connected to a stack, which undergoes a master failover, so that the backup unit takes over, connectivity to the stack may be lost. The backup unit does take over the IP address of the stack, but the management station cannot communicate with the stack using the management IP address. This is due to the fact that the management station associates the management station's IP address with the MAC address of the "old" Master unit. The management station does not update its ARP table, unless the ARP cache of the management station is deleted. It is not possible to copy a configuration file from a TFTP server to the startup configuration, when PVLAN is configured. The switch mistakenly displays native VLANs as if they are configured for all ports, instead of a specified range of ports. The CLI global command "show interfaces port-channel" displays information for inactive LAG port-channels is displayed, but does not show information for configured and inactive LACP port-channels. Ports that are members of the LAG that are not displayed in the WBI, if they are down (no link).Use the channel-group 1 mode auto Interface Configuration command to configure a port as a candidate to dynamically join a LAG (using LACP). These ports are not displayed as LAG members if the interface is down. The network management GUI does not show the stacking port information. Known Restrictions and Limitations Title Broadcast Storm Control Ranges Queue Settings on Cascaded/Stacked Ports Description Storm control rates refer to the average number of frames over a period of time. This period of time decreases as the configured rate increases. For example, configuring a rate of 70 kbps results in a rate of 70 kbps over an average of 1 minute. From rate of 100 it becomes steady. Every port can be set to be either Strict Priority or WRR. This applies to cascading and stacking ports as well. In order to be able to handle high priority traffic across the cascaded links. From an implementation perspective cascaded ports are set to SP. Unicast traffic was assigned to the high priority queue. Therefore, if Unicast traffic is sent at wire-speed, it is prioritized over broadcast traffic to the CPU. This is not a real-life scenario, but should be noted in the Release Notes. ID 34665 33794 System Firmware Version 2.0.0.20 Subject to Change Without Notice Page 2
