Multiport ARP entry configuration example

Network requirements

As shown in Figure 5GigabitEthernet 1/0/1GigabitEthernet 1/0/2GigabitEthernet 1/0/3, a device connects to three servers through interfaces , , and in VLAN 10. The servers share the IP address 192.168.1.1/24 and MAC address 00e0-fc01-0000.

Configure a multiport ARP entry so that the device sends IP packets with the destination IP address 192.168.1.1 to the three servers.

Configuration procedure

# Create VLAN 10.

<Device> system-view
[Device] vlan 10
[Device-vlan10] quit

# Add , , and to VLAN 10.

[Device] interface 
[Device-] port access vlan 10
[Device-] quit
[Device] interface 
[Device-] port access vlan 10
[Device-] quit
[Device] interface 
[Device-] port access vlan 10
[Device-] quit

# Create VLAN-interface 10 and specify its IP address.

[Device] interface vlan-interface 10
[Device-vlan-interface10] ip address 192.168.1.2 24
[Device-vlan-interface10] quit

# Configure a multiport unicast MAC address entry that has MAC address 00e0-fc01-0000, and output interfaces , , and in VLAN 10.

[Device] mac-address multiport 00e0-fc01-0000 interface  to  vlan 10

# Configure a multiport ARP entry with IP address 192.168.1.1 and MAC address 00e0-fc01-0000.

[Device] arp multiport 192.168.1.1 00e0-fc01-0000 10

Verifying the configuration

# Verify that the device has a multiport ARP entry with IP address 192.168.1.1 and MAC address 00e0-fc01-0000.
