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 EMC 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.
interface
Enter any of the following keywords and slot/port or number information:
For a 10-Gigabit Ethernet interface, enter the keyword
TenGigabitEthernet then the stack/slot/port/subport information.
For a 25-Gigabit Ethernet interface, enter the keyword twentyFiveGigE
then the stack/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
the stack/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.
