In addition, this command takes effect on all the ports. However the address aging only
functions on the dynamic addresses (the learned or configured as age entries by the
user).
By default, the aging-time is 300 seconds. With the no-aging parameter, the command
performs no aging on the MAC address entries.

2.2.3 Setting the Max Count of MAC Address Learned by a Port

With the address learning function, an Ethernet switch can learn new MAC addresses.
After received a packet destined some already learned MAC address, the switch will
forward it directly with the hardware, instead of broadcasting. But Too many MAC
address items learned by a port will affect the switch operation performance.
User can control the MAC address items learned by a port through setting the max
count of MAC address learned by a port. If user set 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 count.
You can use the following commands to set the max count of MAC address learned by
a port.
Perform the following configuration in Ethernet port view.
