Configuring The Source Learning Status - Alcatel-Lucent OmniSwitch 9900 Series Network Configuration Manual

Managing Source Learning

Configuring the Source Learning Status

The source learning status for a port or link aggregate of ports is configurable using the
command. For example:
-> mac-learning port 1/10 disable
-> mac-learning port 1/15-20 disable
-> mac-learning linkagg 10 disable
To enable the source learning status for a port or link aggregate, use the source-learning command with
the enable option. For example:
-> mac-learning port 1/10 enable
-> mac-learning port 1/15-20 enable
-> mac-learning linkagg 10 enable
Disabling source learning on a port or link aggregate is useful on a ring configuration, where a switch
within the ring does not need to learn the MAC addresses that the same switch is forwarding to another
switch within the ring,. This functionality is also useful in Transparent LAN Service configurations, where
the service provider device does not need to learn the MAC addresses of the customer network.
Configuring the source learning status is not allowed on the following types of switch ports:
•
Ports enabled with Learned Port Security (LPS).
•
Ports enabled with Universal Network Profile (UNP) functionality.
•
Member ports of a link aggregate.
Consider the following guidelines when changing the source learning status for a port or link aggregate:
•
Disabling source learning on a link aggregate disables MAC address learning on all member ports of
the link aggregate.
•
MAC addresses dynamically learned on a port or aggregate are cleared when source learning is
disabled.
•
Statically configured MAC addresses are not cleared when source learning is disabled for the port or
aggregate. In addition, configuring a new static MAC address is allowed even when source learning is
disabled.
