Increasing The Mac Address Table Size - Alcatel-Lucent OmniSwitch 9900 Series Network Configuration Manual

Managing Source Learning

Increasing the MAC Address Table Size

There are two source learning modes available for the OmniSwitch: centralized and distributed. Enabling
the distributed mode for the switch increases the table size for the switch.
To enable the distributed MAC source learning mode for the chassis, use the
command. When this mode is disabled, the switch operates in the centralized MAC source learning mode
(the default).
Enabling or disabling the distributed MAC source learning mode requires the following three steps:
1
Set the mode.
2
Enter the write memory command to save the switch configuration.
3
Reboot the switch.
For example:
-> mac-learning mode distributed
WARNING: Source Learning mode has changed - must do write memory and reload
-> write memory
-> reload
Note. All three of the above configuration steps are required to enable or disable the MAC mode. If any of
the above steps are skipped, the status of the mode is not changed.
