Discarded Frames

When Discarded Frames is chosen on the general statistics display, the screen
shows the number of frames discarded on the TS port in both inbound (from TS)
and outbound (to TS) directions. The discard reasons are described below.
Discarded Inbound Frames
The following discard reasons are defined for inbound frames:
Invalid VLAN
A frame was received on an unknown VLAN. This is either a VLAN tagged frame
containing an unknown VLAN ID, or an untagged frame when no untagged virtual
ports are defined. Make sure that the 802.1Q VLAN ID and virtual port tagging
mode is set to the same value on both sides of the connection.
Table Invalid VLAN Tag CFI
A VLAN tagged frame with an invalid Canonical Format Indicator (CFI) was
received. The CFI is a bit in the Tag Control Information field of a VLAN tag. This
bit indicates the bit order of any MAC addresses in the information field. It is 0 for
Ethernet format and 1 for Token-Ring format. It should always be 1 in received
frames.
