Microsoft Network Load Balancing
Network Load Balancing (NLB) is a clustering functionality that is implemented by Microsoft on Windows
2000 Server and Windows Server 2003 operating systems. Microsoft NLB clustering allows multiple
servers running Microsoft Windows to be represented by one MAC and one 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 and support for more CAM-ACL to increase.
arp (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 interface
To remove an ARP address, use the no arp ip-address command.
Parameters
ip-address Enter an IP address in dotted decimal format.
multicast-mac-
address
Enter a 48-bit hexadecimal address in nn:nn:nn:nn:nn:nn
format for the static MAC address to be used to switch
multicast traffic.

information:
• For a 10-Gigabit Ethernet interface, enter the keyword
TenGigabitEthernet then the slot/port information.
• For a 40-Gigabit Ethernet interface, enter the keyword
fortyGigE then the slot/port information.
• For a port channel interface, enter the keywords port-
channel then a number.
