IP Version 6 (IPv6) Support
The device functions as an IPv6-compliant host, as well as an IPv4 host (also
known as dual stack). This enables device operation in a pure IPv6 network as
well as in a combined IPv4/IPv6 network.
For more information, see "IP Addressing" on page 202.
Stack Support
The system supports up to eight units with two fixed HDMI stacking ports.
The HDMI ports are 1.3a specification, Category 2 High Speed cables, 340
MHz (10.2 Gbit/s).
it is recommended to use HDMI cable version 1.4
The stacking feature supports the following features:
• Fast-link failover
• Software auto-synch.
• Improved response time to events, such as master failover
• Auto-numbering algorithm when choosing unit number
For more information, see "Stacking Overview" on page 43
Power over Ethernet
Power over Ethernet (PoE) provides power to devices over existing LAN
cabling, without updating or modifying the network infrastructure. When
PoE is used, the network devices do not have to be placed next to a power
source. PoE can be used in the following applications:
• IP Phones
• Wireless Access Points
16 Dell PowerConnect 55xx Systems User Guide
•IP Gateways
•PDAs
• Audio and video remote monitoring
For more information, see "Power over Ethernet" on page 157.
Green Ethernet
Green Ethernet, also known as Energy Efficient Ethernet (EEE), is an effort
to make networking equipment environmentally friendly, by reducing the
power usage of Ethernet connections.
The Short-Reach method, which reduces power over Ethernet cables shorter
than 40m, is supported by the device.
For more information, see "Green Ethernet Configuration" on page 384.
Head of Line Blocking Prevention
Head of Line (HOL) blocking results in traffic delays and frame loss caused
by traffic competing for the same egress port resources. To prevent HOL
blocking, the device queues packets, and packets at the head of the queue are
forwarded before packets at the end of the queue.
Flow Control Support (IEEE 802.3X)
Flow control enables lower-speed devices to communicate with higher-speed
devices, by requesting that the higher-speed device refrain from sending
packets. Transmissions are temporarily halted to prevent buffer overflows.
For more information, see "Flow Control" on page 380.
Back Pressure Support
On half-duplex links, the receiving port prevents buffer overflows by
occupying the link so that it is unavailable for additional traffic.
For more information, see "Protected Ports" on page 388.
Dell PowerConnect 55xx Systems User Guide 17
Virtual Cable Testing (VCT)
VCT
detects and reports copper link cabling faults, such as open cables and
cable shorts.
For more information, see "Diagnostics" on page 248.
Auto-Negotiation
Auto-negotiation enables the device to advertise modes of operation. The
auto-negotiation function enables an exchange of information between two
devices that share a point-to-point link segment, and automatically
configures both devices to take maximum advantage of their transmission
capabilities.
The PowerConnect 5500 series enhances auto-negotiation by providing port
advertisement. Port advertisement enables the system administrator to
configure the port speeds that are advertised.
For more information, see "Port Configuration" on page 397 or "LAG
Configuration" on page 403.
MDI/MDIX Support
Standard wiring for end stations is known as Media-Dependent Interface
(MDI), and standard wiring for hubs and switches is known as Media-
Dependent Interface with Crossover (MDIX).
If auto-negotiation is enabled, the device automatically detects whether the
cable connected to an RJ-45 port is MDIX (crossed) or MDI (straight). This
enables both types to be used interchangeably.
If auto-negotiation is not enabled, only MDI (straight) cables can be used.
For more information, see "Port Configuration" on page 397 or "LAG
Configuration" on page 403.
MAC Address Supported Features
MAC Address Capacity Support
The device supports up to 16K MAC addresses and it reserves specific MAC
addresses for system use.
18 Dell PowerConnect 55xx Systems User Guide
Static MAC Entries
MAC entries can be manually entered in the Bridging Table, as an alternative
to learning them from incoming frames. These user-defined entries are not
subject to aging, and are preserved across resets and reboots.
For more information, see "Static Addresses" on page 418.
Self-Learning MAC Addresses
The device enables controlled MAC address learning from incoming packets.
The MAC addresses are stored in the Bridging Table.
For more information, see "Dynamic Addresses" on page 421.
Automatic Aging for MAC Addresses
MAC addresses from which no traffic is received for a given period, are aged
out. This prevents the Bridging Table from overflowing.
For more information, see "Dynamic Addresses" on page 421.
VLAN-Aware MAC-Based Switching
The device always performs VLAN-aware bridging. Classic bridging
(IEEE802.1D), in which frames are forwarded based only on their destination
MAC address, is not performed. However, a similar functionality can be
configured for untagged frames. Frames addressed to a destination MAC
address that is not associated with any port are flooded to all ports of the
relevant VLAN.
MAC Multicast Support
Multicast service is a limited Broadcast service that enables one-to-many and
many-to-many connections for information distribution. In Layer 2 Multicast
service, a single frame is addressed to a specific Multicast address, from which
copies of the frame are transmitted to the relevant ports. When Multicast
groups are statically enabled, you can set the destination port of registered
groups, as well as define the behavior of unregistered Multicast frames.
For more information, see "Multicast" on page 508.
Dell PowerConnect 55xx Systems User Guide 19
Layer 2 Features
IGMP Snooping
Internet Group Membership Protocol (IGMP) Snooping examines IGMP
frame contents, when they are forwarded by the device from work stations to
an upstream Multicast router. From the frame, the device identifies work
stations configured for Multicast sessions, and which Multicast routers are
sending Multicast frames. The IGMP Querier simulates the behavior of a
Multicast router. This enables snooping of the Layer 2 Multicast domain even
if there is no Multicast router.
For more information, see "IGMP Snooping" on page 519.
Port Mirroring
Port mirroring monitors network traffic by forwarding copies of incoming and
outgoing packets from a monitored port to a monitoring port. Users specify
which target port receives copies of all traffic passing through a specified
source port.
For more information, see "Port Mirroring" on page 411.
Broadcast Storm Control
Storm Control enables limiting the number of Multicast and Broadcast
frames accepted by and forwarded by the device.
When Layer 2 frames are forwarded, Broadcast and Multicast frames are
flooded to all ports on the relevant VLAN. This occupies bandwidth, and
loads all nodes connected on all ports.
For more information, see "Storm Control" on page 408.
20 Dell PowerConnect 55xx Systems User Guide
VLAN Supported Features
VLAN Support
VLANs are collections of switching ports that comprise a single Broadcast
domain. Packets are classified as belonging to a VLAN, based on either the
VLAN tag or on a combination of the ingress port and packet contents.
Packets sharing common attributes can be grouped in the same VLAN.
For more information, see "VLANs" on page 459.
Port-Based Virtual LANs (VLANs)
Port-based VLANs classify incoming packets to VLANs, based on their ingress
port.
For more information, see "Defining VLAN Membership Using CLI
Commands" on page 466.
Full 802.1Q VLAN Tagging Compliance
IEEE 802.1Q defines an architecture for virtual, bridged LANs, the services
provided in VLANs, and the protocols and algorithms involved in the
provision of these services.
For more information, see "Virtual LAN Overview" on page 460.
GVRP Support
GARP VLAN Registration Protocol (GVRP) provides IEEE 802.1Q-
compliant VLAN pruning and dynamic VLAN creation on 802.1Q trunk
ports. When GVRP is enabled, the device registers and propagates VLAN
membership on all ports that are part of the active underlying Spanning Tree
Protocol topology.
For more information, see "GVRP Parameters" on page 483.
Voice VLAN
Voice VLAN enables network administrators to enhance VoIP service by
configuring ports to carry IP voice traffic from IP phones on a specific VLAN.
VoIP traffic has a preconfigured OUI prefix in the source MAC address.
Network administrators can configure VLANs from which voice IP traffic is
