MAC Address Table Configuration
MAC Address Configuration Task List
This chapter is to describe the functions of configuring MAC address table on the switch as follow:
- Configuring static MAC address
- Configuring MAC address aging time
- Configuring black hole MAC address
- Displaying MAC address table
- Removing dynamic MAC address
MAC Address Configuration Tasks
Configuring Static MAC Address
A static MAC address table entry refers to the one that can not be aged by the switch. It only can be deleted manually. Static MAC address can be added or deleted according to the requirements when switches are in use. Enter privilege mode and use the following steps to add or delete a static MAC address.
| Command | Purpose |
|---|---|
| config | Enters the global configuration mode. |
| [no] mac address-table static mac-addr vlan vlan-id interface interface-id |
Add/delete a static MAC address entry. The mac-addr specifiesMACaddress; vlan- id means VLAN number,
the effective range is1~4094; The interface-id is a port name.
exit| Goes back to the EXEC mode.
write| Saves the settings.
Configuring MAC Address Aging Time
When a dynamic MAC address is not used within a specified aging time, the switch will delete it from MAC address table. The MAC aging time of a switch can be set according to actual needs and the default aging time is 300 seconds. Enter EXEC mode, use steps as follow to configure the aging time of MAC address.
| Command | Purpose |
|---|---|
| config | Enters the global configuration mode. |
| mac address-table aging-time [0 | 10-1000000] |
theMACaddress table.
0 means the address does not age; The range of MAC address aging time is
10 to 1,000,000 seconds.
exit| Goes back to the EXEC mode.
write| Saves the settings.
Configuring Black Hole MAC
The black hole MAC address entries mean those MAC address entries that cannot communicate but only be removed manually. Black hole MAC address can be added or deleted according to the requirements when switches are in use. Enter EXEC mode and use the following steps to add or delete a static MAC address.
| Command | Purpose |
|---|---|
| config | Enters the global configuration mode. |
| [no] mac address-table blackholemac-addr vlan vlan-id | Add/delete a black hole |
MAC address entry.
The mac-addr specifiesMACaddress; vlan-id means VLAN number, the effective range is1~4094;
exit| Goes back to the EXEC mode.
write| Saves the settings.
Displaying MAC Address Table
When using switches, we expect to know the information about MAC address table in need of debugging or management. Use show to display MAC address table.
| Command | Purpose |
|---|---|
| show mac address-table [dynamic [interface interface-id | vlan vlan-id] |
| static | brief |
H.H.H | blackhole]
| Dynamic, specify the MAC address dynamically learned.
The interface-id is the interface name. vlan-id VLAN ID. Value range: 1-4094 Static Static MAC address table

Removing Dynamic MAC Address
In some cases, it is necessary to clear up the MAC address which switch has learned. Enter the privileged mode and use the following commands to delete a dynamic MAC address.
| Command | Purpose |
|---|---|
| clear mac address-table dynamic [address mac- addr | interface interface-id |
| vlan vlan-id] | Delete a dynamic MAC address entry. |
dynamic means the MAC address which is learned dynamically. mac-addr means a MAC address.The interface-id is the interface name.
The vlan-id Islan number, The value range is 1 to 4094;
