To set the aging time for dynamic entries, use the following commands:
Configure a Static MAC Address
A static entry is one that is not subject to aging. Static entries must be entered manually. To configure a
static MAC address, use the following command:
Display the MAC Address Table
To display the contents of the MAC address table, use the following command:
Task Command Syntax Command Mode
Disable MAC address aging for all dynamic
entries.
mac-address-table aging-time 0
CONFIGURATION
Specify an aging time. mac-address-table aging-time seconds
Range: 10-1000000
CONFIGURATION
FTOS 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 FTOS clearing entries
closer to the actual desired aging time.
Task Command Syntax Command Mode
Create a static MAC address entry in the MAC address table.
mac-address-table static
CONFIGURATION
Task Command Syntax Command Mode
Display the contents of the MAC address table.
• 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.
