This User’s Guide contains the information needed for installing, configuring and maintaining the Ethernet Switch Module.

PowerConnect 5316M and the Dell Modular Server System

The Dell Modular Server System is based upon the chassis that integrates up to ten Server Modules, up to four I/O modules (including the Ethernet Switch Module), and one or two system management modules called the Dell Remote Access Controller / Modular Chassis (DRAC/MC).
For a list of supported options for the Dell Modular Server System, go to
The Ethernet Switch Module provides switching functions for the Dell Modular Server System. The DRAC/MCs provide a single point of control for the Dell Modular Server System.
The PowerConnect 5316M Ethernet Switch Modules are 16-port Ethernet switch modules connected to Server Modules through the Dell Modular Server Chassis mid-plane.
The ports of the Ethernet Switch Module are divided into internal and external ports.
•
External ports
used for connecting Server Modules to the network.
•
Internal ports
Server Chassis mid-plane. On every Internal Port the speed is fixed to 1000 Mbps.
The console connection to the Ethernet Switch Module is provided only through the DRAC/MC. No access point is provided on the Ethernet Switch Module front panel. For debugging and management purposes, a UART bus of each Ethernet Switch Module is connected to the DRAC/MC. The DRAC/MC can re-direct the serial console interface to only one switch at a time.
The Ethernet Switch Module receives a power supply (12 V dc) through the mid-plane. A single system LED indicates the Ethernet Switch Module status, which is controlled by the DRAC/MC.
The following figure illustrates the PowerConnect 5316M:
— 6 external RJ-45 connectors for 10/100/1000 Base-T copper ports (uplinks)
— 10 internal ports connected to Server Modules through the Dell Modular

General Features

Head of Line Blocking
Head of Line (HOL) blocking results in 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. By default HOL blocking is active at all times except when QoS, Flow Control, or Back Pressure is active on a port, the HOL blocking prevention mechanism is disabled on the whole system.
Flow Control Support (IEEE 802.3X)
Flow control enables lower speed Ethernet Switch Modules to communicate with higher speed Ethernet Switch Modules, by requesting that the higher speed Ethernet Switch Module refrains from sending packets. Transmissions are temporarily halted to prevent buffer overflows.
For information on configuring Flow Control for ports or LAGs, see "Defining Port Parameters" or "Defining LAG Parameters."
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 information on configuring Back Pressure for ports or LAGs, see "Defining Port Parameters" or "Defining LAG Parameters."
Jumbo Frames Support
Jumbo frames are frames with an MTU size of up to 10K bytes, and better utilize the network by transporting the same data using less frames.
The main benefits of this facility are reduced transmission overhead, and reduced host processing overhead. Jumbo are used for server-to-server transfers.
For information on enabling Jumbo Frames, see "Configuring System Information."
10 Introduction
Virtual Cable Testing (VCT)
VCT detects and reports copper link cabling occurrences, such as open cables and cable shorts.
MDI/MDIX Support
The Ethernet Switch Module automatically detects whether the cable connected to an RJ-45 port is crossed or straight through.
Standard wiring for end stations is hubs and switches is known as
Media-Dependent Interface
(MDI) and the standard wiring for
Media-Dependent Interface with Crossover
(MDIX).
For information on configuring MDI/MDIX for ports or LAGs, see "Defining Port Parameters" or "Defining LAG Parameters."
Auto Negotiation
Auto negotiation allows an Ethernet Switch Module to advertise modes of operation. The auto negotiation function provides the means to exchange information between two Ethernet Switch Modules that share a point-to-point link segment, and to automatically configure both Ethernet Switch Modules to take maximum advantage of their transmission capabilities.

MAC Address Supported Features

MAC Address Capacity Support
The Ethernet Switch Module supports up to 4K MAC addresses. The Ethernet Switch Module reserves specific MAC addresses for system use.
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 "Configuring Address Tables."
Self-Learning MAC Addresses
The Ethernet Switch Module enables automatic MAC address learning from incoming packets. The MAC addresses are stored in the Bridging Table.
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 on configuring the MAC Address Age Out Time, see "Configuring Address Tables."
Introduction 11
VLAN-aware MAC-based Switching
The Ethernet Switch Module always performs VLAN-aware bridging. Classic bridging(IEEE802.1D) is not performed, where frames are forwarded based only on their destination MAC address. However, a similar functionality may be configured for untagged frames. Addresses are associated with ports by learning them from the incoming frames source address. This is done by the CPU. When a frame is sent from an unknown source address, the frame is forwarded to the CPU. The CPU adds the source address to the Forwarding tables. Additional frames sent to or from this address are correctly handled by the hardware. Frames addressed to a destination MAC address that is not associated with any port are flooded to all ports of the relevant VLAN.
www.dell.com | support.dell.com
MAC Multicast Support
Multicast service is a limited broadcast service, which allows one-to-many and many-to-many connections for information distribution. Layer 2 Multicast service is where a single frame is addressed to a specific Multicast address, from where copies of the frame are transmitted to the relevant ports.
For more information, see "Multicast Forwarding Support."

Layer 2 Features

IGMP Snooping
IGMP Snooping examines IGMP frame contents, when they are forwarded by the Ethernet Switch Module from work stations to an upstream Multicast router. From the frame, the Ethernet Switch Module identifies work stations configured for Multicast sessions, and which Multicast routers are sending Multicast frames.
For more information, see "IGMP Snooping."
Port Mirroring
Port mirroring monitors and mirrors 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 "Defining Port Mirroring Sessions."
Broadcast Storm Control
Storm Control enables limiting the amount of Multicast and Broadcast frames accepted and forwarded by the Ethernet Switch Module.
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 "Enabling Storm Control."
12 Introduction

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 based 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 "Configuring VLANs."
Port Based Virtual LANs (VLANs)
Port-based VLANs classify incoming packets to VLANs based on their ingress port.
For more information, see "Defining VLAN Ports Settings."
IEEE802.1V Protocol Based Virtual LANs (VLANs)
VLAN classification rules are defined on data-link layer (Layer 2) protocol identification. Protocol­based VLANs isolate Layer 2 traffic for differing Layer 3 protocols.
For more information, 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. An important requirement included in this standard is the 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 Ethernet Switch Module registers and propagates VLAN membership on all ports that are part of the active underlying
"Spanning Tree Protocol Features" on page 13
topology.
For more information, see "Configuring GVRP."

Spanning Tree Protocol Features

Spanning Tree Protocol (STP)
802.1d Spanning tree is a standard Layer 2 switch requirement 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 more information, see "Configuring the Spanning Tree Protocol."
Introduction 13
Fast Link
STP can take up to 30-60 seconds to converge. During this time, STP detects possible loops, allowing time for status changes to propagate and for relevant Ethernet Switch Modules to respond. 30-60 seconds is considered too long of a response time for many applications. The Fast Link option bypasses this delay, and can be used in network topologies where forwarding loops do not occur.
For more information enabling Fast Link for ports and LAGs, see "Defining STP Port Settings"
"
Defining STP LAG Settings."
IEEE 802.1w Rapid Spanning Tree
Spanning Tree can take 30-60 seconds for each host to decide whether its ports are actively

forwarding traffic. Rapid Spanning Tree (RSTP) detects uses of network topologies to enable faster convergence, without creating forwarding loops.
For more information, see "Configuring Rapid Spanning Tree."

Link Aggregation

For more information, see "Aggregating Ports."
Link Aggregation
Up to six Aggregated Links may be defined, each with up to six member ports, to form a single Link Aggregated Group (LAG). This enables:
• Fault tolerance protection from physical link disruption
• Higher bandwidth connections
• Improved bandwidth granularity
• High bandwidth server connectivity
LAG is composed of ports with the same speed, set to full-duplex operation.
or
NOTE: Only the six external port can be added to LAG.
For more information, see "Defining LAG Membership."
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 port binding to aggregators within the system.
For more information, see "Defining LACP Parameters."
