Introduction 25
Standard wiring for end stations is Media-Dependent Interface (MDI) and the standard wiring for
hubs and switches is known as Media-Dependent Interface with Crossover (MDIX).
For information about configuring MDI/MDI for ports or LAGs, see "Defining Port Configuration"
or "Defining LAG Configuration."
Hardware Watchdog Support
The switch uses Hardware Watchdog to detect issues and take corrective action when the software
stops responding.
Auto Negotiation
Auto negotiation allows the device to advertise modes of operation. The auto negotiation function
provides the means to exchange information between two devices that share a point-to-point link
segment, and to automatically configure both devices to take maximum advantage of their
transmission capabilities.
The PowerConnect 6024/6024F enhances auto negotiation by providing port advertisement. Port
advertisement allows the system administrator to configure the port speeds advertised.
For information about auto negotiation, see "Defining Port Configuration" or "Defining LAG
Configuration."
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 refrains from sending packets. Transmissions are temporarily halted to
prevent buffer overflows.
For information about configuring flow control for ports or LAGs, see "Defining Port
Configuration" or "Defining LAG Configuration."
Head of Line Blocking Prevention
Head of Line (HOL) blocking prevents traffic delays and frame loss caused by traffic competing for
the same egress port resources. HOL blocking queues packets, and the packets at the head of the
queue are forwarded before packets at the end of the queue.
Back Pressure Support
On half-duplex links, a receiver may prevent buffer overflows by occupying the link so that it is
unavailable for additional traffic.
For information about configuring Back Pressure for ports or LAGs, see "Defining Port
Configuration" or "Defining LAG Configuration."

26 Introduction

MAC Address Supported Features
MAC Address Support
The switch supports up to 16K MAC addresses and reserves specific MAC addresses for system use.
Self-Learning MAC Addresses
The switch enables MAC addresses to be automatically learned from incoming packets.
Automatic Aging for MAC Addresses
MAC addresses that have not seen any traffic for a given period are aged out, which prevents the
Bridging Table from overflowing.
For information about configuring the MAC Address age-out period, see "Viewing Dynamic
Addresses."
Static MAC Entries
User-defined MAC entries are stored in the Bridging Table with the self-learned addresses.
For information about configuring the static MAC addresses, see "Defining Static Addresses."
VLAN-Aware MAC-based Switching
Packets arriving from an unknown source address are sent to the CPU and added to the Hardware
Table. Future Packets addressed to or from this address are more efficiently forwarded.
MAC Multicast Support
Multicast service is a limited broadcast service that allows one-to-many and many-to-many
connections. In Layer 2 multicast services, a single frame addressed to a specific multicast address
is received, and copies of the frame to be transmitted on each relevant port are created.
For information about configuring MAC Multicast Support, see "Multicast Forwarding Support."
Layer 2 Features
IGMP Snooping
IGMP Snooping examines the contents of IGMP frames when they are forwarded by the switch
from stations to an upstream multicast router. Snooping enables the switch to identify stations
interested in multicast sessions and which multicast routers are sending multicast frames.
For information about configuring IGMP Snooping, see "IGMP Snooping."
Port Mirroring
Port mirroring monitors and mirrors network traffic by forwarding copies of incoming and outgoing
packets from one port to a monitoring port.

Introduction 27
For information about configuring port mirroring, see "Defining Port Mirroring Sessions."
Broadcast Storm Control
When Layer 2 frames are forwarded, broadcast and multicast frames are flooded to all ports on the
relevant VLAN. The flooding occupies bandwidth, and loads all nodes connected on all ports.
Storm control limits the amount of multicast and broadcast frames accepted and forwarded by the
switch.
For information about configuring storm control, see "Enabling Storm Control."
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 a combination of the ingress
port and packet contents. Packets sharing common attributes can be groups in the same VLAN.
For information about configuring VLANs, see "Configuring VLANs."
Port-Based VLANs
Port-based VLANs classify incoming packets to VLANs based on their ingress port.
For information about configuring VLANs, see "Configuring VLANs."
IEEE802.1V Protocol Based VLANs
VLAN classification rules are defined on data-link layer (Layer 2) protocol identification. Protocol-
based VLANs are used for isolating Layer 2 traffic for differing Layer 3 protocols.
For information about defining Protocol Based VLANs, see "Defining VLAN Protocol Groups."
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.
This standard requires an ability to mark frames with a desired Class of Service (CoS) tag
value (0-7).
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 switch registers and
propagates VLAN membership on all ports that are part of the active underlying Spanning Tree
protocol topology.
For information about configuring GVRP, see "Configuring GVRP. "

28 Introduction
www.dell.com | support.dell.com
Private VLAN Edge
Private VLAN Edge (PVE) ports are a Layer 2 security feature that provides port-based security
between adjacent ports within a VLAN. It is an extension of the common VLAN. Traffic from
protected ports is sent only to the uplink ports and cannot be sent to other ports within the VLAN.
For information about configuring PVE ports, see "Configuring Ports".
Spanning Tree Protocol Features
Spanning Tree Protocol (STP) per Device
802.1d STP is a standard requirement of Layer 2 switches that allows bridges to automatically
prevent and resolve L2 forwarding loops. Switches exchange configuration messages, using
specifically formatted frames, and selectively enable and disable forwarding on ports.
For information about configuring STP, see "Configuring the Spanning Tree Protocol."
Fast Link
STP can take as long as 30-60 seconds to converge as it detects possible loops and allows time for
status changes to propagate and for relevant devices to respond. This duration is considered too
long for many applications. Fast Link bypasses this delay without requiring multiple data paths for
network resiliency.
For information about enabling Fast Link for ports and LAGs, see "Defining Port Configuration" or
"Defining LAG Configuration."
IEEE 802.1W Rapid Spanning Tree
Rapid Spanning Tree Protocol (RSTP) detects uses network topologies to enable faster
convergence, without creating forwarding loops.
For information about enabling RSTP, see "Defining the Rapid Spanning Tree."
Multiple Spanning Tree
Multiple Spanning Tree (MSTP) operation maps VLANs into ST instances. MSTP provides a
differing load balancing scenario. Packets assigned to various VLANs are transmitted along
different paths within MSTP Regions (MST Regions). Regions are one or more interconnected
MSTP bridges with identical MSTP settings. The standard lets administrators assign VLAN traffic
to unique paths.
For more information about MSTP, see "Defining the Multiple Spanning Tree".

Introduction 29
Link Aggregation
Link Aggregation
Up to seven ports can combine to form a single Link Aggregated Group (LAG). This enables fault
tolerance protection from physical link disruption, higher bandwidth connections and improved
bandwidth granularity.
A LAG is composed of ports of the same speed, set to full-duplex operation.
For information about configuring LAGs, see "Defining LAG Configuration."
Link Aggregation and LACP
LACP uses peer exchanges across links to determine, on an ongoing basis, the aggregation
capability of various links, and continuously provides the maximum level of aggregation capability
achievable between a given pair of systems. LACP automatically determines, configures, binds, and
monitors the binding of ports to aggregators within the system.
For information about LACP, see "Defining LACP Parameters."
Routing Features
IP Routing
IP routing forwards to a next-hop device any packets that are addressed to the system MAC
addresses but not to a system IP address.
For information about configuring IP routing, see "Configuring Global IP Routing."
RIP Versions 1 and 2
Routing Information Protocol (RIP) is a distance-vector routing protocol. RIP selects routes based
on the hop count to the destination. RIP 2 enhances the efficiency, usability, and authentication
methods of the RIP protocol.
For information about configuring RIP, see "Configuring RIP."
OSPF Version 2
Open Shortest Path First (OSPF) is an internal gateway routing protocol. In networks with a large
number of inter-connected routers, OSPF is more efficient than RIP because OSPF uses less link
bandwidth and converges more quickly.
For information about configuring OSPF, see "Configuring OSPF Parameters and Filters."

30 Introduction
www.dell.com | support.dell.com
Address Resolution Protocol (ARP)
In IP routing, routers and Layer 3 switches use various routing protocols to discover network
topology and define routing tables. ARP automatically determines Device Next-Hop MAC
addresses of systems, including directly attached end systems. Users can override and supplement
this by defining additional ARP table entries
.
For information about configuring ARP, see "Defining ARP Settings."
ICMP Messages
Internet Control Message Protocol (ICMP) messages are used for out-of-band messages related to
network operation or malfunction.
IGMPv2
IGMP enables the router to send IGMP queries in the form of L2 broadcasts over each interface.
When a multicast packet is sent, and it has a multicast destination MAC address, all hosts on that
router interface receive a copy. Hosts listen to all IGMP reports. If interested multicast groups have
already been requested by any station on the same interface, the remaining stations do not send
duplicate requests.
For information about configuring IGMP, see "Defining IGMP Interface Parameters."
Longest Prefix Match Support
Longest prefix matches are used primarily to determine the best next-hop route for a packet based
solely on the destination address contained in the packet header. Because IP addresses are generally
assigned in a manner that reflects the topology of the network, the result of a longest prefix match
usually reflects the shortest route to the destination.
DVMRP
Distance Vector Multicast Routing Protocol (DVMRP) advertises the shortest-path routes to
multicasting source networks with hosts that can transmit multicast IP traffic.
For information about configuring DVMRP, see "Configuring DVMRP Interfaces."
VRRP
Virtual Router Redundancy Protocol (VRRP) eliminates single points of failure in the routing
environment. VRRP uses an election protocol that dynamically assigns responsibility for the virtual
router to one of the VRRP routers in the LAN.
The election process provides dynamic failover in the forwarding responsibility, if the master is
unavailable. Any virtual router IP address can be used as a default first-hop router by end-hosts.
For information about configuring VRRP, see "Configuring VRRP."
