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

Enter an IP address in dotted decimal format.

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.

Enter any of the following keywords and slot/port or number 
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.
