Introduction1-15Figure 1-7 illustrates how the SmartSTACK 10 ELS10-26 can beused in a backbone network configuration using increasedbandwidth of the Fast Ethernet configuration.Figure 1-7. SmartSTACK 10 ELS10-26 Backbone ConfigurationVirtual WorkgroupsThe SmartSTACK 10 ELS10-26 allows you to define ports forlogical groups of associated devices (virtual workgroups) toprovide a more efficient flow of traffic across your Ethernetnetwork. You can define a maximum of eight virtual workgroups.Virtual workgroups offer you the ability to limit broadcasts tological domains within the network. Workgroup destinations arerecognized by the SmartSTACK 10 ELS10-26 and broadcast packetsare routed directly to hosts within the workgroup, eliminating theneed to perform a general broadcast across each segment of thenetwork to find specific host addresses.ELS10-26TXSTATUSPORT STATUS MODE10BASE-T/100BASE-TXFEPIM2X 4X 6X 8X 10X 12X 14X 16X 18X 20X 22X 24X MONX 26X27LINKSTATUSLINKSTATUS2627LINKSTATUSLINKSTATUSLINKSTATUSLINKSTATUSLINKSTATUSLINKSTATUS131415162324212217181920LINKSTATUSLINKSTATUSLINKSTATUSLINKSTATUSLINKSTATUSLINKSTATUS341278561112910TX ACT FDX MONRX COL 100 USRPWRCPURESET25MONCOMELS10-26TXSTATUSPORT STATUS MODE10BASE-T/100BASE-TXFEPIM2X 4X 6X 8X 10X 12X 14X 16X 18X 20X 22X 24X MONX 26X27LINKSTATUSLINKSTATUS2627LINKSTATUSLINKSTATUSLINKSTATUSLINKSTATUSLINKSTATUSLINKSTATUS131415162324212217181920LINKSTATUSLINKSTATUSLINKSTATUSLINKSTATUSLINKSTATUSLINKSTATUS341278561112910TX ACT FDX MONRX COL 100 USRPWRCPURESET25MONCOM10BASE-T Cables10BASE-T CablesServersELS10-26ELS10-26Network SwitchWAN RouterNetworkManagementStationWorkgroupHub100 Mbps (Fast Ethernet)
