Disabling LLDP or LLDP-MED will effectively disable EEE, IEEE 802.3at PoE+ high power negotiation and Dell EqualLogic array detection in the iSCSI Optimization feature.
PAGE 14
 Strong Passwords The strong passwords feature allows administrators to specify that local switch passwords meet certain characteristics considered to enhance network security. Administrators are advised that the minimum character classes configuration must be enabled (value equal to 1 or greater) along with enabling the strong password feature before the other minimum character class configurations are enforced. These character class configurations are: • Minimum number of uppercase letters.

Release 4.2.0.4  LAG Limits Ports can be formed into LAGs in a more flexible manner. The system supports up to 128 total LAGs. Up to 144 ports can be assigned to dynamic LAGs.
PAGE 18
 New Web Interface The Web interface has been enhanced with new navigation features for ease of use.  CLI Syntax Changes The CLI has changed significantly to be compatible with the PowerConnect switch standard CLI. Configurations for previous releases may not be compatible with this release and may need to be updated. Refer Configuration Migration document for more info.  Unit/Slot/Port Naming Conventions In-band interfaces are named based on stack unit, slot, and port. Units range from 1-12.

Only VLANs that are configured on the switch will forward traffic. The PowerConnect switches implements the 802.1Q-2005 standard which builds on 802.1D-2004. 802.1D-2004 incorporates the 802.1t, 802.1w and 802.1s revisions.
PAGE 20
Switchport Mode Configuration Preserved: When switching between switchport modes (access, trunk, and general), the switchport configuration applicable to the selected mode is maintained. This means that when switching from one mode to another and back, the port will have the same configuration as it had in the original mode. Only the configuration applicable to the selected mode is active on the port.

The interface configuration overrides the global configuration for the selected interface. Relay Information Option Check: When DHCP Option-82 insertion is enabled for a relay agent, the server should echo received Option 82 unaltered back toward the client.

User’s Configuration Guide Updates The following table lists issues found in the User’s Configuration Guide after publication: Release 5.1.0.1 Issue The following paragraphs need to be added to the User’s Guides for all platforms except the PCM6220: Unknown unicast and multicast packets are copied to the CPU on the lowest priority QoS queue. Unknown packets are those that do not have hardware forwarding entries. Known unicast/multicast packets are hardware forwarded and are not queued to the CPU.

Known Issues The following are all the outstanding known issues from previous releases. The issues listed here may have been discovered on any of the switches listed on the title page. Release 5.1.0.1 Summary User Impact Workaround Molex QSPF DAC Cable with part number 111040-1104 does not comply with QSFP specification SFF-8436. These cables do not support 'voltage' diagnostics. Show AAA IAS-USERS Command Missing Voltage is displayed as 0.00 instead of "N/A" for this diagnostic parameter.

Summary The following unwanted logs may come up on console after running the “show tech-support” command with UDLD and MSTP configured: “ATP RX: Failed to alloc” logs On PC8100 switches, console gets locked for 20-30 seconds if trying to add a 6to4 tunnel source within 30 seconds of deleting another tunnel source.

SNMP V3 walk may fail after “initiate failover” command is issued. OOB static IP entry cannot be the same as the DHCP assigned IP address User Impact If the port is operating in Trunk mode and UDLD is enabled, the port goes down if it is excluded from the native vlan.
PAGE 64
Summary SNMP walk is not successful while doing walk on root port. FIP sessions are getting disconnected for VLAN switchport mode change with default vlan settings. User Impact SNMP walk on the root port times out. Workaround Users are unlikely to change either the default VLAN or the FIP VLAN while sessions are active. Do not change the FIP VLAN while sessions are established.

Workaround Transmit Errors is seen on port channel, but not on the members of the port channel. Counters remain inaccurate. None – Inaccurate transmit errors do not cause functional issues.

Summary Password strength minimum characters not enforced User Impact Operator may become confused regarding switch operations. M8024-k OpenManage Web UI stack view display Operators using IE 8 may experience issues as follows: (1) Status LED does not glow to identify Master (2) Member units do not show "DELL PowerConnect M8024-k" model info (3) Member units port display is missing (4) LED label should be "Unit No." instead of "Stack No." ? (5) All Stack No.

Upgrade to a PowerConnect switch that supports LLPF like a PCM6348 switch.
PAGE 68
Summary User Impact Workaround ST : Stack member response times to ICMP ping requests in a 12 unit stack are larger than for stack master 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. None required. Issue with protocol based VLAN configuration migration.

Release 5.0.0.4 System – 5.0.0.4 System Description User Impact 8100 switches increment “Internal MAC Rx Errors” counter, when packets are received with (size > 1518) and (size <= MTU size), and the packet contains an invalid FCS or code error detected or an IEEE length check error Low For typical IP networks this problem won't be seen because the length field/Ethertype will contain a valid value. Web Description User Impact The device manager GUI does not support IE9 at this time.

Data Center – 4.2.0.4 Interoperability Description VLAN request/Notification counters are not incremented for priority tagged packets User Impact Low – FIP sessions are established and are displayed in the show commands. FIP snooping VLAN request or VLAN response counters do not increment when CNA sends priority tagged frames (i.e. VID 0). It is observed that certain CNAs sometimes sends FIP VLAN discovery frames as 802.1Q tagged frames with VID=0 and priority as FCoE priority.
