Disabling static source check

By default, the static source check feature is enabled on an interface. The check identifies whether a received frame meets the following conditions:

The source MAC address of the frame matches a static MAC address entry.
The incoming interface of the frame is different from the outgoing interface in the entry.

If the frame meets both conditions, the switch drops the frame.

When this feature is disabled, the switch does not perform the check for a received frame. It can forward the frame whether or not the frame meets the conditions.

To disable the static source check feature:

Step	Command	Remarks
1. Enter system view.	system-view	N/A
2. Enter interface view.	Enter Layer 2 Ethernet interface view:interface interface-type interface-number Enter Layer 2 aggregate interface view:interface bridge-aggregation interface-number Enter Layer 3 Ethernet interface/subinterface view:interface interface-type { interface-number \| interface-number.subnumber } Enter Layer 3 aggregate interface/subinterface view:interface route-aggregation { interface-number \| interface-number.subnumber }	N/A
3. Disable the static source check feature.	undo mac-address static source-check enable	By default, the static source check feature is enabled.
