73
column indicates whether pause frames on the port
are transmitted. The Rx and Tx settings are
determined by the result of the last Auto Negotiation.
Check the configured column to use flow control. This
setting is related to the setting for Configured Link
Speed.
NOTICE: The 100FX standard doesn't support Auto
Negotiation, so when in 100FX mode the flow control
capabilities will always be shown as "disabled".
PFC
When PFC (802.1Qbb Priority Flow Control) is
enabled on a port then flow control on a priority level is
enabled. Through the
Priority
field, range (one or
more) of priorities can be configured, e.g. '0-3,7' which
equals '0,1,2,3,7'. PFC is not supported through auto
negotiation. PFC and Flow control cannot both be
enabled on the same port.
Maximum Frame Size
Enter the maximum frame size allowed for the switch
port, including FCS. The range is 1518-10240 bytes.
Excessive Collision Mode
Configure port transmit collision behavior.
Discard
: Discard frame after 16 collisions (default).
Restart
: Restart backoff algorithm after 16 collisions.
Frame Length Check
Configures if frames with incorrect frame length in the
EtherType/Length field shall be dropped. An Ethernet
frame contains a field EtherType which can be used to
indicate the frame payload size (in bytes) for values of
1535 and below. If the EtherType/Length field is above
1535, it indicates that the field is used as an EtherType
(indicating which protocol is encapsulated in the
payload of the frame). If "frame length check" is
enabled, frames with payload size less than 1536
bytes are dropped, if the EtherType/Length field
doesn't match the actually payload length. If "frame
length check" is disabled, frames are not dropped due
to frame length mismatch. Note: No drop counters
count frames dropped due to frame length mismatch
