Configure the MAC learning limit on the
interface or port group
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 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.
Required
No MAC learning limit is
configured by default.
