Functional Descriptions

VMDS-10488 VSC7511 Datasheet Revision 4.2

•

Frames with a null source or null destination MAC address (address = 0x000000000000)

•

Frames with errors signaled by the MAC (for example, an FCS error)

•

MAC control frames

•

Pause frames after flow control processing in the MAC.

•

Untagged frames (excluding frames with reserved destination MAC addresses from the BPDU,

GARP, and Link trace/CCM address ranges).

•

Priority S-tagged frames

•

Priority C-tagged frames

•

VLAN S-tagged frames

•

VLAN C-tagged frames

By default, MAC control frames, pause frames, and frames with errors are dropped by the classifier.

The VLAN acceptance filter decides whether a frame’s VLAN tagging is allowed on the port. By default,

the outer VLAN tag is used as input to the filter, however, there is an option to use the inner VLAN tag

instead for double tagged frames (VLAN_CFG.VLAN_INNER_TAG_ENA).

The following illustration shows the flowchart for the VLAN acceptance filter.
