Disabling static source check
About 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 device drops the frame.
When this feature is disabled, the device does not perform the check for a received frame. It can
forward the frame whether or not the frame meets the conditions.
Restrictions and guidelines
To correctly forward traffic sourced from the MAC address of a VLAN interface, you must disable the
static source check feature on the Layer 2 interfaces in the VLAN.
