Release Notes

16 System Firmware Version 5.1.1.7
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
 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. Slots range from 0-2. Ports
range from 1-48. Slots for plug-in modules are numbered 1 and 2. Fixed ports belong to slot 0.
The service port is still addressed using the out-of-band keyword.
 Management VLAN Deprecated
The PowerConnect series switches do not have an in-band management VLAN by default. Administrators can
designate a VLAN for support of in-band management operations.
 VLAN interface configuration mode enables routing
When executing the “interface vlan x” command, routing is automatically enabled on that VLAN.
 Service/Out-of-band Ethernet Port Defaults to DHCP Addressing
By default, the service/out-of-band Ethernet port will attempt to obtain an address via DHCP.
NOTE: It is recommended that administrators attach the service/out-of-
band Ethernet port to a physically separate network for out-of-band
network management. The service port does not offer routing or
switching capabilities nor does it offer enhanced protection from DOS
attacks. Configure a VLAN on one or more in-band interfaces for
management of PowerConnect switches over the operational network.
 LACP Ports Inactive Until Attached
Ports in a LAG configured to use LACP (dynamic LAG) remain inactive (discard received traffic) until they become
attached to the LAG. LACP ports that are attached to a LAG will enter the discarding state if they become detached
from the LAG for any reason.
Port level configuration for a port that is configured in a dynamic LAG is disregarded. Remove the port from the LAG
to restore use of the port level configuration.
Ports in a static LAG begin forwarding on link up. Ports in a static LAG disregard port level configuration. Configure
static LAG functions on the static LAG interface.
