1-8Configuration ExampleAdding a Static MAC Address Entry ManuallyNetwork requirementsThe server connects to the switch through Ethernet 1/0/2. To prevent the switch from broadcastingpackets destined for the server, it is required to add the MAC address of the server to the MAC addresstable of the switch, which then forwards packets destined for the server through Ethernet 1/0/2.z The MAC address of the server is 000f-e20f-dc71.z Port Ethernet 1/0/2 belongs to VLAN 1.z Suppose the MAC address of a host is 000f-e235-abcd and belongs to VLAN 1. Because the hostonce behaved suspiciously on the network, you can add a blackhole MAC address entry for theMAC address to drop all packets destined for the host for security sake.Configuration procedure# Enter system view. system-view[Sysname]# Add a MAC address, with the VLAN, ports, and states specified.[Sysname] mac-address static 000f-e20f-dc71 interface Ethernet 1/0/2 vlan 1# Add a black hole MAC address 000f-e235-abcd, with the VLAN and ports specified.[Sysname] mac-address blackhole 000f-e235-abcd interface Ethernet 1/0/2 vlan 1# Display information about the current MAC address table.[Sysname] display mac-address interface Ethernet 1/0/2MAC ADDR VLAN ID STATE PORT INDEX AGING TIME(s)000f-e20f-dc71 1 Config static Ethernet1/0/2 NOAGED000f-e235-abcd 1 Blackhole Ethernet1/0/2 NOAGED000f-e20f-a7d6 1 Learned Ethernet1/0/2 AGING000f-e20f-b1fb 1 Learned Ethernet1/0/2 AGING000f-e20f-f116 1 Learned Ethernet1/0/2 AGING--- 4 mac address(es) found on port Ethernet1/0/2 ---
