PowerConnect M6220/M6348/8024/8024F/M8024/M8024-k/ 7024/7048/7024P/7048P/7024F/7048R/7048R-RA Release Notes Known Issues Summary DUT delivers more power than the PD requested via LLDP in high power mode. L3 routing NSF failover data plane on dynamic LAG - loss duration up to 5 seconds for large configurations Trunk mode VLANs transmit tagged frames only User Impact DUT may draw more power than negotiated at short cable lengths. PD may draw more power than negotiated, but power loss due to cable impedance is compensated for so that devices with average or longer cable length will receive adequate power. Interruption of voice, video and data service for duration of loss. Data plane loss during failover should not exceed 50 ms. Not compatible with other vendors trunk modes. Speed/duplex commands available for interfaces which require auto-negotiation Confusion about how to configure links. ST : Stack member response times to ICMP ping requests in a 12 unit stack are larger than for stack master Issue with protocol based VLAN configuration migration. Read/write user allowed read only access when authentication method is used as TACACS. No user impact expected. Observed occasional outlier response time up to 500 ms for stack members in a large stack configuration with heavy traffic. Average response time is well under 100 ms for stack members. All response times are well within ping limits. The command vlan protocol group required a string parameter in earlier versions; now it requires an integer parameter. The user always gets Read-Only access if using TACACS as a means for HTTP authentication, even if the TACACS user is Read/Write capable. TFTP gives no reason for file download failures. Generic failure message is issued. CLI command stackport config rejection does not display the cause. The 'acct-port' command does not have 'no' version. If a user enters an invalid interface, a generic error message is issued. The user can configure the acct-port to the default using the positive form of the command Workaround None - system assumes 5.8W average loss due to cable length and delivers 5.8W extra power to ensure device receives requested power. Disable portfast and auto-portfast on physical ports configured in a LAG. Administrators can configure "general" mode VLANs, which transmit PVID frames untagged and all other VLAN frames tagged. General mode is compatible with other vendor's trunk mode behavior. Documentation and CLI prompt clearly states which commands are applicable to which interfaces. Only use speed/duplex commands on fiber interfaces. Only use speed auto/duplex auto commands on copper interfaces. None required. The software recognizes if the group name is alphanumeric, however it will not work when the name of the group is numeric (for example 2, 3, etc.). User can configure the same TACACS user locally and use LOCAL authentication method for HTTP. The user will be able to get access based on the local user access level (Read-write or Read-only). Administrators can ping the TFTP server from the switch. Administrators should ensure the TFTP server is available, the requested file is available, and the permissions are set correctly. Utilize the show stack-port command to identify stack port configuration issues. Configure the acct-port to the default using the acct-port 1813 command in Radius accounting mode.
