CONFIGURATION mode
mac-address-table aging-time seconds
The range is from 10 to 1000000.
Dell Networking OS Behavior: The time elapsed before the configured MAC aging time expires is not
precisely as configured. For example, the VLAN configuration mac-address-table aging-time 1,
does not remove dynamic entries from the CAM after precisely 1 second. The actual minimum aging time
for entries is approximately 5 seconds because this is the default MAC address table scanning interval.
Therefore, MAC aging configurations of less than 5 seconds, as in this example, might be ineffective.
Configuring mac-address-table station-move time-interval 500 solves this limitation.
Reducing the scanning interval to the minimum (500 milliseconds), increases the detection speed, which
results in the system clearing entries closer to the actual desired aging time.

Configuring a Static MAC Address

A static entry is one that is not subject to aging. Enter static entries manually.
To create a static MAC address entry, use the following command.
• Create a static MAC address entry in the MAC address table.
CONFIGURATION mode
mac-address-table static

Displaying the MAC Address Table

To display the MAC address table, use the following command.
• Display the contents of the MAC address table.
EXEC Privilege mode
show mac-address-table [address | aging-time [vlan vlan-id]| count | dynamic
| interface | static | vlan]
–address: displays the specified entry.
–aging-time: displays the configured aging-time.
–count: displays the number of dynamic and static entries for all VLANs, and the total number of
entries.
–dynamic: displays only dynamic entries.
–interface: displays only entries for the specified interface.
–static: displays only static entries.
–vlan: displays only entries for the specified VLAN.
MAC Learning Limit
MAC address learning limit is a method of port security on Layer 2 port-channel and physical interfaces,
and VLANs. It allows you to set an upper limit on the number of MAC addresses that learned on an
