Configures the FDB (forwarding database) aging time for dynamic entries.
| agingtime | If agingtime is set to 0, all aging entries in the database are defined as static, nonaging entries. |
| seconds | Specifies the FDB aging time, in seconds. A value of 0 indicates that the entry should never be aged out. All other platforms support the value 0 (no aging) and a range of 15 to 1,000,000 seconds. |
300.
If the aging time is set to 0 (zero), all dynamic entries in the database become static, nonaging entries. This means that they do not age out, but non-permanent static entries can be deleted if the switch is reset.
The software flushes the FDB table once the aging timeout parameter is reached, even if the switch is running traffic and populating addresses in the FDB table.
For Summit X460-G2 switches, the hardware flushes the FDB table at periods based on the configured software aging time. The actual hardware aging time does not exactly match the software aging time and can be as high as twice the configured software aging time.
The following example sets the FDB aging time to 3,000 seconds:
configure fdb agingtime 3000
This command was first available in ExtremeXOS 10.1.
