Set The Aging Time For Dynamic Entries; Configure A Static Mac Address - Dell Force10 S4810P Configuration Manual

Set the Aging Time for Dynamic Entries

Learned MAC addresses are entered in the table as dynamic entries, which means that they are subject to
aging. For any dynamic entry, if no packet arrives on the switch with the MAC address as the source or
destination address within the timer period, the address is removed from the table. The default aging time
is 1800 seconds.
Task
Disable MAC address aging for all dynamic
entries.
Specify an aging time.
Set the Aging Time for Dynamic Entries on a VLAN
Set the Aging Time for Dynamic Entries on a VLAN is available only on platform:
Task
Specify an aging time.
FTOS Behavior: The time elapsed before the configured MAC aging time expires is not precisely as configured.
For example, the VLAN configuration
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
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.

Configure a Static MAC Address

A static entry is one that is not subject to aging. Static entries must be entered manually:
Task
Create a static MAC address entry in the MAC address table.
