Source Learning Commands
page 18-8 OmniSwitch 6250 CLI Reference Guide November 2009
source-learning
Configures the status of source MAC address learning on a single port, a range of ports, or on a link
aggregate of ports.
source-learning {port slot/port1[-port2] | linkagg linkagg_num} {enable | disable}
Syntax Definitions
slot/port1 The slot number for the module and the physical port number on that
module (e.g., 3/1 specifies port 1 on slot 3).
-port2 The last port number in a range of ports that you want to configure on
the same slot (e.g, 3/1-4 specifies ports 1, 2, 3, and 4 on slot 3).
linkagg_num Specifies the link aggregate port ID.
enable Enables source learning.
disable Disables source learning.
Defaults
By default, source learning is enabled on all ports.
Platforms Supported
OmniSwitch 6250-Metro Models
Usage Guidelines
• Configuring source learning is not supported on mobile ports, Learned Port Security ports, individual
ports which are members of a link aggregate, or Access Guardian (802.1x) ports.
• When port-based source learning is configured for a link aggregate ID, it affects all the ports that are
members of the link aggregate.
• When source-learning is disabled on a port or link aggregate, all dynamically learned MAC addresses
are removed from the MAC address table.
• Static MAC addresses associated with a port or link aggregate are not cleared when source learning is
disabled. Also, new static MAC address configurations are allowed on ports or link aggregates even
when source learning is disabled on them.
• Disabling source learning on a port or link aggregate is useful on a ring configuration where switch A
does not have to learn MAC addresses from switch B or for a Transparent LAN Service, where the
service provider does not require the MAC addresses of the customer network.
Examples
-> source-learning port 1/2 disable
-> source-learning port 1/3-9 disable
-> source-learning linkagg 10 disable
