It also describes the installation and initial configuration procedures.
Page 52 Introduction...
Page 53: Switch Features
Switch Features This section describes the switch user-configurable software features. NOTE: Before proceeding, read the release notes for this product. The release notes are part of the firmware download. The topics covered in this section include: • System Management • Link Aggregation Features Features &...
Page 54: System Management Features
Multiple Management Options You can use any of the following methods to manage the switch: • Use a Web browser to access the Dell OpenManage Switch Administrator interface. The switch contains an embedded Web server that serves HTML pages. •...
Page 55: Port Aggregator
Port Aggregator The Port Aggregator feature minimizes the administration required for managing the PowerConnect M6220/M6348/M8024/M8024-k switch. When the switch is operating in simple mode, the administrator can map internal ports to external ports without having to know anything about STP, VLANs, Link Aggregation or other L2/L3 protocols.
Page 56: Integrated Dhcp Server
Integrated DHCP Server PowerConnect M6220, M6348, M8024, and M8024-k switches include an integrated DHCP server that can deliver host-specific configuration information to hosts on the network. The switch DHCP server allows you to configure IP address pools (scopes), and when a host’s DHCP client requests an address, the switch DHCP server automatically assigns the host an address from the pool.
Page 57: File Management
File Management You can upload and download files such as configuration files and system images by using HTTP (web only), TFTP , Secure FTP (SFTP), or Secure Copy (SCP). Configuration file uploads from the switch to a server are a good way to back up the switch configuration.
Page 58: Sflow
sFlow sFlow is the standard for monitoring high-speed switched and routed networks. sFlow technology is built into network equipment and gives complete visibility into network activity, enabling effective management and control of network resources. The PowerConnect M6220, M6348, M8024, and M8024-k switches support sFlow version 5. For information about configuring managing sFlow settings, see "Monitoring Switch Traffic"...
Page 59: Stacking Features (Pcm6220 And Pcm6348 Only)
Stacking Features (PCM6220 and PCM6348 Only) NOTE: PowerConnect M6220 switches can be stacked only with other PowerConnect M6220 switches. PCM6220 and PCM6348 switches cannot be combined within the same stack. For information about creating and maintaining a stack of switches, see "Managing a Switch Stack"...
Page 60: Master Failover With Transparent Transition
Master Failover with Transparent Transition Standby The stacking feature supports a or backup unit that assumes the Master unit role if the Master unit in the stack fails. As soon as a Master failure is detected in the stack, the Standby unit initializes the control plane and enables all other stack units with the current configuration.
Page 61: Password-Protected Management Access
Password-Protected Management Access Access to the Web, CLI, and SNMP management interfaces is password protected, and there are no default users on the system. For information about configuring local user accounts, see "Controlling Management Access" on page 171. Strong Password Enforcement The Strong Password feature enforces a baseline password strength for all locally administered users.
Page 62: Ssh/Ssl
SSH/SSL The switch supports Secure Shell (SSH) for secure, remote connections to the CLI and Secure Sockets Layer (SSL) to increase security when accessing the Web-based management interface. For information about configuring SSH and SSL settings, see "Controlling Management Access" on page 171. Inbound Telnet Control You can configure the switch to prevent new Telnet sessions from being established with the switch.
Page 63: Dot1X Authentication (Ieee 802.1X)
Dot1x Authentication (IEEE 802.1X) Dot1x authentication enables the authentication of system users through a local internal server or an external server. Only authenticated and approved system users can transmit and receive data. Supplicants are authenticated using the Extensible Authentication Protocol (EAP). Also supported are PEAP , EAP-TTL, EAP-TTLS, and EAP-TLS.
Page 64: Access Control Lists (Acl)
Access Control Lists (ACL) Access Control Lists (ACLs) ensure that only authorized users have access to specific resources while blocking off any unwarranted attempts to reach network resources. ACLs are used to provide traffic flow control, restrict contents of routing updates, decide which types of traffic are forwarded or blocked, and above all provide security for the network.
Page 65: Dhcp Snooping
DHCP Snooping DHCP Snooping is a security feature that monitors DHCP messages between a DHCP client and DHCP server. It filters harmful DHCP messages and builds a bindings database of (MAC address, IP address, VLAN ID, port) tuples that are specified as authorized. DHCP snooping can be enabled globally and on specific VLANs.
Page 66: Switching Features
For information about how to configure the AFS CLI Reference Guide feature, see the available at support.dell.com/manuals. Jumbo Frames Support Jumbo frames enable transporting data in fewer frames to ensure less overhead, lower processing time, and fewer interrupts.
Page 67: Vlan-Aware Mac-Based Switching
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. 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.
Page 68: Port Mirroring
Port Mirroring Port mirroring monitors and mirrors network traffic by forwarding copies of incoming and outgoing packets from up to four source ports to a monitoring port. The switch also supports flow-based mirroring, which allows you to copy certain types of traffic to a single destination port. This provides flexibility— instead of mirroring all ingress or egress traffic on a port the switch can mirror a subset of that traffic.
Page 69: Connectivity Fault Management (Ieee 802.1Ag)
Connectivity Fault Management (IEEE 802.1ag) NOTE: The Connectivity Fault Management feature is available only on the PowerConnect M6348. The Connectivity Fault Management (CFM) feature, also known as Dot1ag, supports Service Level Operations, Administration, and Management (OAM). CFM is the OAM Protocol provision for end-to-end service layer instance in carrier networks.
Page 70: Virtual Local Area Network Supported Features
Virtual Local Area Network Supported Features For information about configuring VLAN features see "Configuring VLANs" on page 575. 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.
Page 71: Garp And Gvrp Support
GARP and GVRP Support The switch supports the configuration of Generic Attribute Registration Protocol (GARP) timers GARP VLAN Registration Protocol (GVRP) relies on the services provided by GARP to provide 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 spanning tree protocol topology.
Page 72: Spanning Tree Protocol Features
Spanning Tree Protocol Features For information about configuring Spanning Tree Protocol features, see "Configuring the Spanning Tree Protocol" on page 633. Spanning Tree Protocol (STP) Spanning Tree Protocol (IEEE 802.1D) is a standard requirement of Layer 2 switches that allows bridges to automatically prevent and resolve L2 forwarding loops.
Page 73: Bridge Protocol Data Unit (Bpdu) Guard
Bridge Protocol Data Unit (BPDU) Guard Spanning Tree BPDU Guard is used to disable the port in case a new device tries to enter the already existing topology of STP. Thus devices, which were originally not a part of STP, are not allowed to influence the STP topology. BPDU Filtering When spanning tree is disabled on a port, the BPDU Filtering feature allows BPDU packets received on that port to be dropped.
Page 74: Routing Features
Routing Features Address Resolution Protocol (ARP) Table Management You can create static ARP entries and manage many settings for the dynamic ARP table, such as age time for entries, retries, and cache size. For information about managing the ARP table, see "Configuring IP Routing" on page 895.
Page 75: Bootp/Dhcp Relay Agent
BOOTP/DHCP Relay Agent The switch BootP/DHCP Relay Agent feature relays BootP and DHCP messages between DHCP clients and DHCP servers that are located in different IP subnets. For information about configuring the BootP/DHCP Relay agent, see "Configuring L2 and L3 Relay Features" on page 919. IP Helper and UDP Relay The IP Helper and UDP Relay features provide the ability to relay various protocols to servers on a different subnet.
Page 76: Virtual Router Redundancy Protocol (Vrrp)
Virtual Router Redundancy Protocol (VRRP) VRRP provides hosts with redundant routers in the network topology without any need for the hosts to reconfigure or know that there are multiple routers. If the primary (master) router fails, a secondary router assumes control and continues to use the virtual router IP (VRIP) address.
Page 77: Ipv6 Routes
IPv6 Routes Because IPv4 and IPv6 can coexist on a network, the router on such a network needs to forward both traffic types. Given this coexistence, each switch maintains a separate routing table for IPv6 routes. The switch can forward IPv4 and IPv6 traffic over the same set of interfaces.
Page 78: Quality Of Service (Qos) Features
Quality of Service (QoS) Features NOTE: Some features that can affect QoS, such as ACLs and Voice VLAN, are described in other sections within this chapter. Differentiated Services (DiffServ) The QoS Differentiated Services (DiffServ) feature allows traffic to be classified into streams and given certain QoS treatment in accordance with defined per-hop behaviors.
Page 79: Priority-Based Flow Control (Pfc)
Priority-based Flow Control (PFC) NOTE: PFC is supported only on the PCM8024-k. The PCM6220, PCM6348, and PCM8024 switches do not support PFC. The Priority-based Flow Control feature allows the user to pause or inhibit transmission of individual priorities within a single physical link. By configuring PFC to pause a congested priority (priorities) independently, protocols that are highly loss sensitive can share the same link with traffic that has different loss tolerances.
Page 80: Layer 2 Multicast Features
Layer 2 Multicast Features For information about configuring L2 multicast features, see "Configuring L2 Multicast Features" on page 713. 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.
Page 81: Multicast Vlan Registration
Multicast VLAN Registration NOTE: MVR is not supported on the PowerConnect M6220. The Multicast VLAN Registration (MVR) protocol, like IGMP Snooping, allows a Layer 2 switch to listen to IGMP frames and forward the multicast traffic only to the receivers that request it. Unlike IGMP Snooping, MVR allows the switch to listen across different VLANs.
Page 82: Protocol Independent Multicast-Dense Mode
Protocol Independent Multicast—Dense Mode Protocol Independent Multicast (PIM) is a standard multicast routing protocol that provides scalable inter-domain multicast routing across the Internet, independent of the mechanisms provided by any particular unicast routing protocol. The Protocol Independent Multicast-Dense Mode (PIM- DM) protocol uses an existing Unicast routing table and a Join/Prune/Graft mechanism to build a tree.

Page 119: Default Network Information
Destination Unreachable, Fragmentation needed but DF set an ICMP notification, the switch will reduce the MSS. However, many firewalls block ICMP Destination Unreachable messages, which causes the destination to request the packet again until the connection times out. In order to resolve this issue, you can reduce the MSS setting to a more appropriate value on the local host or alternatively, you can set the MTU on the PowerConnect management port to a smaller value.
