Table 253
Set the MAC Address Aging Time for the System
In addition, this command takes effect on all the ports. However the address aging
only functions on the dynamic addresses (manual entries added to the Switch are
not aged).
By default, the
aging-time
is 300 seconds. With the
no-aging
parameter, the
command performs no aging on the MAC address entries.
Setting the Max Count of MAC Addresses Learned by a Port
With the address learning function, a Switch can learn new MAC addresses. After
it receives a packet destined for an already learned MAC address, the Switch will
forward it directly with the hardware, instead of broadcasting it. However, too
many MAC address items learned by a port will affect the Switch operation
performance.
You can control the MAC address items learned by a port through setting the max
count of MAC addresses learned by a port. If a user sets the max count value of a
port as
count
, the port will not learn new MAC address items when the count of
MAC address items reaches the
count
value.
You can use the following commands to set the max count of MAC addresses
learned by a port.
Perform the following configuration in Ethernet Port View.

By default, there is no limit to the MAC addresses learned via the Ethernet port.
Displaying MAC Address
Table
After the above configuration, execute the
display
command in all views to
display the running of the MAC address table configuration, and to verify the
effect of the configuration.
Execute the
debugging
command in User View to debug MAC address table
configuration.
