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 Ethernet
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 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.
Enter Layer 2 Ethernet
interface view
Enter port group view
Use the command...
display mac-address [ mac-address [ vlan vlan-id ] |
[ [ dynamic | static ] [ interface interface-type
interface-number ] | blackhole ] [ vlan vlan-id ]
[ count ] ] [ | { begin | exclude | include }
regular-expression ]
display mac-address aging-time [ | { begin |
exclude | include } regular-expression ]
display mac-address mac-learning [ interface-type
interface-number ] [ | { begin | exclude | include }
regular-expression ]
display mac-address statistics [ | { begin | exclude |
include } regular-expression ]
Use the command...
system-view
interface interface-type
interface-number
port-group manual
port-group-name
mac-address
max-mac-count count
21
Remarks
Use either command.
The configuration made in Layer 2
Ethernet interface view takes effect
on the current interface only. The
configuration made in port group
view takes effect on all the member
ports in the port group.
