Introduction

The Dell™ PowerConnec t™ 5500 Series Systems CLI Transition Guide White Paper outlines the changes in
the CLI commands from the PowerConnect 54XX and 35XX software to the 4.x software release on the
5500 Series switches. Changes include syntax and functional updates as specified in the following
sections.

Changes to the Interface Naming Conventions

On the Dell PowerConnect 5500, the interface naming convention is the industry standard format of
interface type (gigabitethernet or tengigabitethernet), unit ID, Slot number and port number. The user
can also use the short form of the interface type (gi or te). For example, the name of first
gigabitethernet port of unit ID 2 is: gi2/0/1 or gigabitethernet2/0/1.

VLAN Enhancements

The configuration of VLANs in this software release is much more flexible than previous releases:

Shadow VLAN Configuration

In previous products, the user could configure interface level VLAN commands only if they matched
current port’s VLAN mode. For example, if port is in access mode, user could not configure commands
related to general mode.

On the Dell PowerConnect 5500, the user can configure any VLAN command, even if not related to the
current port VLAN mode. Configuration of inactive VLAN modes are kept as “shadow configuration”
until the relevant mode is applied. The user can view shadow and active configurations via the “show
interface switchport” command.

Adding a port which is a VLAN memb er t o a L AG

In previous products, the user could not add a port to a LAG if the port was a member in any VLAN
besides the default VLAN.

On the Dell PowerConnect 5500, the user can add a port to a LAG even if it is a member of one or more
VLANs. The VLAN configuration on the port becomes inactive until the port is removed from LAG, since
the Port acquires the VLAN configuration of the LAG. The user can view this information via the “show
interface switchport” command.

Configuring IP Address on a port w h ich is a member of VLANs

In previous products, the user could configure an IP Address on a port only if the port was not a
member of any VLAN besides the default VLAN. IP configuration would become active immediately
after command execution.

On the Dell PowerConnect 5500, the user can define an IP Address on a port even if it is a member of
one or more VLANs. To activate IP Interface on a port, the user must apply the CLI command “no
switchport”, which enables L3 capabilities on a port. The user can view this information via “show
interface switchport” command.

Enhanced functionality in Trunk mode

On the Dell PowerConnect 5500, ports set to Trunk mode now carries all VLANs (by default) that are
created and active on the device, and an inactive member of VLANs that were not created. The port
PVID (native VLAN) can be configured to a VLAN that does not exist on the device. Untagged frames
will be classified to the VLAN whose VID is configured as the port’s PVID. Frames to all other VLANs
active on the port will be sent tagged.

Enhancement to IGMP Snooping

IGMP Snooping configuration was modified to an industry standard configuration, which includes:
robustness, query-interval, query-max-response-time, last-member-query-count and last-member­query-interval. In the Dell PowerConnect 5500, the IGMP Snooping timers are automatically exported
from the received queries and the user does not need to configure them manually.

Additional ACL Options

The enhancement to ACLs includes support for time-based ACLs, and support for logging information on
packets dropped due to deny rules. On the Dell PowerConnect 5500, the user can configure IPv6 rules,
in addition to the IPv4 rules and MAC rules.

Modification in Power-Over-Ethernet

In previous products, the power limit was based on the Class Mode of the powered device.
On the Dell PowerConnect 5500, the user has control of the allocated power per port.

Enhancement to Stack Configuration

On the Dell PowerConnect 5500, configuring the stack unit numbers is more intuitive and the automatic
numbering feature for each unit is enabled by default.

Enhancement to QoS Ingress Rate Limit

On the Dell PowerConnect 5500, the ingress rate limit is based on the Policer mechanism, which makes
it much more accurate than in the previous products, and also makes it possible to use ingress rate
limit and storm control on a the same port.
