7024/7048/7024P/7048P/7024F
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. Up to 72 LAGs can be configured as dynamic. A LAG may contain up to 8 ports.
The M8024 supports 12 total LAGs (static or dynamic) with up to 24 ports assigned to dynamic LAGs.
 Stacking Over Ethernet Ports only on M8024-k/8024/8024F
Stacking is supported over standard Ethernet SFP+ ports. The ports must be configured as stacking ports.

EqualLogic arrays to utilize spanning-tree portfast and unicast storm disable.
Release 4.1.1.9
 No Changed Functionality in this Release
Release 4.1.0.19
 PHY microcode upgrade process
The PHY microcode upgrade process has been enhanced to upgrade the PHY microcode to the latest version based on
PHY revision. If the user experiences problems links on the combo ports after the upgrade completes, a reboot may be
required in order to activate the new PHY firmware.
 Asymmetric flow control
Asymmetric flow control is implemented for the PC8024X, PCM8024, PCM6348, PC70XX, and PCM8024-k
switches. The switch does not generate pause frames when congested. It will honor pause frames as per industry
standards.
Release 4.1.0.6
 Authentication
The enable and line authentication methods will no longer perform authentication if a password for the method is not
configured. Previously, these methods would always succeed if no password was configured. To achieve the same
functionality, add the "none" method to the list after enable or line method.
The default authentication list for telnet and SSH has been changed to enableNetList. The only authentication method
contained in enableNetList is enabled. The net effect of these two changes is that a password is required to enter
privileged exec mode when using telnet or SSH.
Administrators wishing to maintain the previous PowerConnect behavior can set the default authentication list for
telnet and SSH to enableList, which has the enable and none authentication methods (no password required to enter
privileged exec mode). The following commands change the telnet authentication method to enableList.
console(config)# line telnet
console(config)# enable authentication enableList
console(config)# exit
