Microsoft Network Load BalancingNetwork load balancing (NLB) is a clustering functionality that is implemented by Microsoft on Windows 2000 Server and Windows Server2003 operating systems. Microsoft NLB clustering allows multiple servers running Microsoft Windows to be represented by one MAC andone IP address to provide transparent failover and load-balancing. The Dell Networking OS does not recognize server clusters by default;you must configure NLB functionality on a switch to support server clusters. The maximum NLB entry limit from 8 to 11 is increased andsupport for more CAM-ACL to increase.Topics:• arp (for Multicast MAC Address)• mac-address-table static (for Multicast MAC Address)• ip vlan-floodingarp (for Multicast MAC Address)To associate an IP address with a multicast MAC address in the switch when you configure multicast mode of network load balancing(NLB), use address resolution protocol (ARP).Syntax arp ip-address multicast-mac-address interfaceTo remove an ARP address, use the no arp ip-address command.Parameters ip-address Enter an IP address in dotted decimal format.multicast-mac-addressEnter a 48-bit hexadecimal address in nn:nn:nn:nn:nn:nn format for the static MACaddress to be used to switch multicast traffic.interface Enter any of the following keywords and slot/port or number information:• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet thenthe stack/slot/port/subport information.• For a 25-Gigabit Ethernet interface, enter the keyword twentyFiveGigE then thestack/slot/port/subport information.• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the stack/slot/port[/subport] information.• For a 50-Gigabit Ethernet interface, enter the keyword fiftyGigE then the stack/slot/port/subport information.• For a 100-Gigabit Ethernet interface, enter the keyword hundredGigE then thestack/slot/port information.• For a port channel interface, enter the keywords port-channel then a number.• The interface specified here must be one of the interfaces configured using the{output-range | output} interface option with the mac-address-table static command.Defaults Not configured.30980 Microsoft Network Load Balancing
