Displaying And Maintaining Mac Address Tables; Mac Address Table Configuration Example - H3C S5500-EI Series Configuration Manual

NOTE:
Layer 2 aggregate interfaces do not support the mac-address max-mac-count command.
•
Do not configure the MAC learning limit on any member ports of an aggregation group. Otherwise, the
•
member ports cannot be selected.

MAC address table configuration example

Network requirements
The MAC address of one host is 000f-e235-dc71 and belongs to VLAN 1. It is connected to
•
GigabitEthernet 1/0/1 of the device. To prevent MAC address spoofing, add a static entry into the
MAC address table of the device for the host.
The MAC address of another host is 000f-e235-abcd and belongs to VLAN 1. Because this host
•
once behaved suspiciously on the network, you can add a destination blackhole MAC address
entry for the MAC address to drop all packets destined for the host.
Set the aging timer for dynamic MAC address entries to 500 seconds.
•
Configuration procedure
# Add a static MAC address entry.
<Sysname> system-view
[Sysname] mac-address static 000f-e235-dc71 interface gigabitethernet 1/0/1 vlan 1
# Add a destination blackhole MAC address entry.
[Sysname] mac-address blackhole 000f-e235-abcd vlan 1
# Set the aging timer for dynamic MAC address entries to 500 seconds.
[Sysname] mac-address timer aging 500
# Display the MAC address entry for port GigabitEthernet 1/0/1.
[Sysname] display mac-address interface gigabitethernet 1/0/1
