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-member-
query-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.
