HPE 3100 Configuration Manual page 18

•
Add Ethernet 1/0/1 and Ethernet 1/0/4 into VLAN 2, and specify IP address 17.1.1.1/24 for
VLAN-interface 2.
•
Specify 17.1.1.1/24 as the default gateway of Host A and Host B.
•
Specify 16.1.1.30/24 as the default gateway of Server A and Server B.
•
Disable the ARP entry check function so that the switch can learn dynamic ARP entries
containing multicast MAC addresses.
•
Configure a static multicast MAC address entry so that only interfaces Ethernet 1/0/2 and
Ethernet 1/0/3 can receive multicast information.

Configuration procedure
This example only describes multicast ARP configuration on the switch, and is only applicable to
multicast NLB. For NLB configuration on the servers, see the related documents of the Windows
Server.

Verifying the configuration
•
NLB load sharing—Enables the FTP server function of Server A and Server B. Host A and
Host B send requests to the virtual IP address and each of them logs in to a different server.
