Features

This section describes the switch’s user-configurable features. For a list of all features, refer to the software version release notes.

Port Based Features

Virtual Cable Testing (VCT)

VCT detects and reports potential copper link cabling issues, such as cable opens or cable shorts.

Jumbo Frames Support

Jumbo frames enables transporting identical data in fewer frames to ensure less overhead, lower processing time, and fewer interrupts.

MDI/MDIX Support

Your switch supports auto-detection between crossed and straight-through cables.

24 Introduction

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."

Introduction 25

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.

www.dell.com | support.dell.com

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.

26 Introduction

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. Protocolbased 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. "

Introduction 27

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

www.dell.com | support.dell.com

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".

28 Introduction

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."

Introduction 29

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.

www.dell.com | support.dell.com

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."

30 Introduction

Layer 3 Features

TCP

Transport Control Protocol (TCP) connections are defined between 2 ports by an initial synchronization exchange. TCP ports are identified by an IP address and a 16-bit port number. Octets streams are divided into TCP packets, each carrying a sequence number.

UDP Relay

UDP Relay enables the device to forward specific UDP broadcasts from one interface to another. IP broadcast packets from one interface are not generally forwarded to another interface. However, some applications use UDP broadcast to detect the availability of a service. Other services require UDP broadcast packets to be routed to provide services to clients on another subnet.

BootP and DHCP Clients

DHCP enables additional setup parameters to be received from a network server upon system startup. DHCP service is an on-going process. DHCP is an extension to BootP.

For information about DHCP, see "Defining DHCP IP Interface Parameters."

BootP Relay

BootP enables a device to solicit and receive configuration data from servers. If the intended BootP server is not directly attached to a client’s broadcast domain, a BootP relay service enables the client to reach the server.

DHCP Relay

DHCP enables a device to solicit and receive configuration data from servers. If the intended DHCP server is not directly attached to a client’s broadcast domain, a DHCP relay service enables the client to reach the server.

For information about configuring DHCP Relay parameters, see "Defining DHCP Relay Parameters."

Quality of Service Features

Quality of Service (QoS) Support

To overcome unpredictable network traffic and optimize performance, you can apply Quality of Service (QoS) throughout the network to ensure that network traffic is prioritized according to specific criteria. Your switch supports two modes of QoS: basic and advanced.

Introduction 31

Class Of Service 802.1p Support

The IEEE 802.1p signaling technique is an OSI Layer 2 standard for tagging and prioritizing network traffic at the data link/MAC sub-layer. The 802.1p traffic is classified and sent to the destination; no bandwidth reservations or limits are established or enforced. The 802.1p standard establishes eight levels of priority, similar to the IP Precedence IP Header bit-field.

Quality of Service Basic Mode

In basic QoS mode, it is possible to activate a trust mode (to trust VPT, DSCP, TCP/UDP or none). In addition, a single access control list can be attached to an interface.

For information about enabling QoS Basic Mode, see "Configuring Basic QoS Mode."

www.dell.com | support.dell.com

Quality of Service Advanced Mode

Advanced Quality of Service mode specifies flow classification and assigns rule actions that relate to bandwidth management. These rules can be grouped into a policy, which can be applied to an interface.

For information about enabling QoS Advanced Mode, see

Device Management Features

SNMP Alarms and Trap Logs

The system logs events with severity codes and timestamps. The events are sent as SNMP traps to a trap recipient list.

For information about SNMP Alarms and Traps, see "Defining SNMP Parameters."

Web Based Management

You can manage the system from any web browser. The switch contains an embedded web server that serves HTML pages that you can use to monitor and configure the system.

Configuration File Download

The switch’s configuration file includes both system-wide and port-specific device configuration data. You can display configuration files through CLI commands.

For information about downloading configuration files, see "Downloading Files."

Configuring Advanced QoS Mode."

Software Download

Software download enables storage of backup firmware images. For information about downloading the software, see

32 Introduction

Software Download and Reboot."

Trivial File Transfer Protocol (TFTP)

PowerConnect 6024/6024F supports boot image, firmware and configuration upload/download via TFTP.

Remote Monitoring

Remote monitoring (RMON) is an extension to the SNMP that provides comprehensive network

traffic

monitoring capabilities (as opposed to SNMP, which allows network

device

management and monitoring). RMON is a standard MIB that defines current and historical MAC-layer statistics and control objects, allowing real-time information to be captured across the entire network.

For information about RMON, see

Simple Network Management Protocol (SNMP) Versions 1, 2 and 3

Viewing RMON Statistics."

To control access to the system, a list of community entries is defined, each of which consists of a community string and its access privileges. There are three levels of SNMP security — read-only, read-write, and super. Only a super-user can access the community table itself.

Command Line Interface

Command Line Interface (CLI) syntax and semantics conform as much as possible to common industry practice. CLI is composed of mandatory and optional elements. Context-sensitive help provides format and value ranges allowed for current commands, and the CLI interpreter provides command and keyword completion.

Syslog

Syslog is a protocol that allows event notifications to be sent to a set of desired remote servers where they can be stored, examined, and acted upon.

For information about Syslog, see

Managing Logs."

SNTP

The Simple Network Time Protocol (SNTP) assures accurate network switch clock time synchronization up to the millisecond. Time synchronization is performed by a network SNTP server.

For more information about SNTP, see "Configuring SNTP Settings."

Traceroute

Traceroute enables discovering IP routes that packets were forwarded along during the forwarding process. The CLI Traceroute utility can be executed from either User EXEC or Privileged EXEC modes.

Introduction 33

Out-of-Band Management Port Support

An out-of-band management port is an external Ethernet port that carries only traffic between the system-administrator and the management applications. The out-of-band management port provides a physically secure link and also offers fault tolerance.

Security Features

Access Control Lists (ACL)

ACL provides rules for forwarding or blocking network traffic. You can define ACLs to enforce security enhancements by defining classification rules and assigning an action per rule. You can assign an ACL to an ingress interface (port or VLAN).

www.dell.com | support.dell.com

For information about defining ACLs, see "Defining IP based ACLs" and "Defining MAC based ACLs."

Port Based Authentication (802.1x)

Port based authentication enables authenticating system users on a per port basis via an external server. Only authenticated and approved system users can transmit and receive data. Ports are authenticated via the Remote Authentication Dial In User Service (RADIUS) server using the Extensible Authentication Protocol (EAP).

For more information, see "Configuring Port Based Authentication."

Locked Port Support

Locked port limits access on a port only to users with specific MAC addresses. These addresses are manually defined or learned on that port. When a frame is seen on a locked port, and the frame source MAC address is not tied to that port, the protection mechanism is invoked.

For information about enabling locked port security, see

Configuring Port Security."

Password Management Security

Password management provides increased network security and improved password control. Passwords for SSH, Telnet, HTTP, HTTPS and SNMP access are assigned security features.

For more information about password management, see "Managing Passwords".

TACACS+

TACACS+ provides centralized security for validation of users accessing the switch. TACACS+ provides a centralized user management system, while still retaining consistency with RADIUS and other authentication processes.

For information about defining TACACS+ settings, see "Configuring Out-of-Band TACACS+ Servers" and "Configuring TACACS+ Settings."

34 Introduction

RADIUS Client

RADIUS is a client/server-based protocol in which the server maintains a user database, that contains per-user authentication information, such as user name, password and accounting information.

For information about defining RADIUS settings, see "Configuring RADIUS Settings."

SSH

Secure Shell (SSH) is a protocol that provides a secure, remote connection to a device. This connection provides functionality that is similar to an inbound telnet connection.
