Page 143: Advanced Topics
HAPTER DVANCED OPICS The SMC6724L2 supports Layer 2 switching and other advanced features which are described in this chapter. Layer 2 Switching When a frame enters a port, its destination MAC address is checked in the address database to see which port leads to this destination.
Page 144: Unicast Switching
DVANCED OPICS The following sections provide additional information about the tasks the switch performs during unicast and multicast switching. Unicast Switching This section describes VLAN classification, learning, filtering, and forwarding for unicast switching. • VLAN Classification—When the switch receives a frame, it classifies the frame in one of two ways: - If the frame is untagged, the switch classifies the frame into the default VLAN for the incoming port.
Page 145: Multicast Switching
AYER WITCHING - If unknown, the switch floods the received frame to all ports in the VLAN, excluding the source port. - If known, the switch forwards the received frame to the port associated with the pair. At the same time, the switch decides whether a VLAN tag needs to be added to or stripped from the frame, depending on the VLAN tagged/untagged configuration and VLAN ID for the output port.
Page 146: Spanning Tree Algorithm
DVANCED OPICS Spanning Tree Algorithm The Spanning Tree Algorithm (that is, the STA-configuration algorithm as outlined in IEEE 802.1D) can be used to detect and disable network loops, and to provide link backup. This allows the switch to interact with other bridging devices (including STA- compliant switches, bridges or routers) in your network to ensure that only one route exists between any two stations on the network.
Page 147: Virtual Lans
IRTUAL The following figure gives an illustration of how the Spanning Tree Algorithm assigns bridging device ports. Root Bridging Device Designated Port Designated Port Root Port Root Port Blocking Designated Port Designated Port Designated Port Root Port Root Port Root Port Virtual LANs Switches do not inherently support broadcast domains, which can lead to broadcast storms in large networks that handle a lot of...
Page 148: Assigning Ports To Vlans
DVANCED OPICS VLANs provide greater network efficiency by reducing broadcast traffic, and allow you to make network changes without having to update IP addresses or IP subnets. VLANs inherently provide a high level of network security since traffic must pass through a configured Layer 3 link to reach a different VLAN.
Page 149: Vlan Classification
IRTUAL VLAN Classification When the switch receives a frame, it classifies the frame in one of two ways. If the frame is untagged, the switch assigns the frame to an associated VLAN (based on the PVID of the receiving port (page 2-43 and 3-36).
Page 150: Forwarding Tagged/Untagged Frames
DVANCED OPICS the specified VLANs, and pass the message on to all other ports. VLAN requirements are propagated in this way throughout the network. This allows GVRP-compliant devices to be automatically configured for VLAN groups based solely on endstation requests. Forwarding Tagged/Untagged Frames Ports can be assigned to multiple tagged or untagged VLANs.
Page 151: Multicast Filtering
ULTICAST ILTERING Multicast Filtering Multicasting sends data to a group of nodes instead of a single destination. The simplest way to implement multicasting is to broadcast data to all nodes on the network. However, such an approach wastes a great deal of bandwidth if the target group is small compared to the overall broadcast domain.
Page 152: Igmp Protocol
DVANCED OPICS traffic, and allows you to significantly reduce the multicast traffic passing through your switch. IGMP Protocol The Internet Group Management Protocol (IGMP) runs between hosts and their immediately adjacent multicast router/switch. IGMP is a multicast host registration protocol that allows any host to inform its local router that it wants to receive transmissions addressed to a specific multicast group.

S) S LASS ERVICE UPPORT similar join packet to all other ports on the switch, informing them that incoming multicast traffic for the stated group is to be forwarded to the requesting port. Class-of-Service (CoS) Support The SMC6724L2 provides two transmit queues on each port, with a weighted fair queuing scheme.
Page 154: Security Features
DVANCED OPICS Security Features The SMC6724L2 provides security features which allow you to control management access and network access as described in the following sections. SNMP Community Strings Access to the switch using network management tools is controlled by SNMP community strings. This switch supports up to five community strings.
Page 155: Mac Address Filters
SNMP M ANAGEMENT OFTWARE MAC Address Filters If you discover that some nodes are sending abnormal or destructive data that could adversely affect the network or cause security problems, you can set their MAC addresses to be filtered by the switch. Any packets with a source or destination address listed in the MAC address filter will then be dropped by the switch upon entry.
Page 156: Remote Monitoring (Rmon)
DVANCED OPICS Remote Monitoring (RMON) Remote Monitoring provides a cost-effective way to monitor large networks by placing embedded or external probes on distributed network equipment (hubs, switches or routers). RMON has already become a valuable tool for network managers faced with a quickly changing network landscape that contains dozens to hundreds of separate segments.
