Source Learning Commands
OmniSwitch 6250 CLI Reference Guide November 2009 page 18-3
• Select the filtering parameter to set up a denial of service to block potential hostile attacks. Traffic sent
to or from a filtered MAC address is dropped. Select the bridging parameter for regular traffic flow to
or from the MAC address.
• If a packet received on a port associated with the same VLAN contains a source address that matches a
static MAC address, the packet is discarded.
• Static MACs are not supported on mobile ports.
• Only static MAC address entries with a permanent management status are captured when a snapshot
of the switch’s running configuration is taken.
• Use the mac-address-table aging-time command (see page 18-6) to set the aging time value for all
static and dynamically learned MAC addresses. This is the value applied to static MAC addresses
defined using the mac-address-table timeout form of this command.
