Normally, you are recommended to use the default aging time, namely, 300 seconds.
The no-aging keyword specifies that MAC address entries do not age out.
1.2.4 Setting the Maximum Number of MAC Addresses a Port Can Learn
The MAC address learning mechanism enables an Ethernet switch to acquire the
MAC addresses of the network devices on the segment connected to the ports of the
switch. The switch directly forwards the packets destined for these MAC addresses. A
MAC address table too big in size may decrease the forwarding performance of the
switch.
By setting the maximum number of MAC addresses that can be learnt from individual
ports, you can control the number of the MAC address entries the MAC address table
can dynamically maintains. When the number of the MAC address entries learnt from
a port reaches the set value, the port stops learning MAC addresses.
