Link Stability as %
Link Down Count

Link Drop Count
(up to 4 for 100BaseT
and 10 for 1000BaseT)
Perform a fixed format Link Monitor test given a specified link
rate. Test port must be properly linked at the desired rate that is
provided in the command line. Link Rate of 10, 100, or 1000
MUST be provided. Utility will return Link Stability as a % where
100% means total link stability. Will also return a count of
“down” links and “dropped” links discovered for each 100
samples collected.
10 Assess link stability on a 10BaseT Link. Link monitor will take
400 samples of instantaneous link status over a 20 second
period with relinks following each 100 successful samples
collected.
100 Assess link stability on a 100BaseTx Link. Link monitor will
take 400 samples of instantaneous link status over a 20
second period with relinks following each 100 successful
samples collected.
1000 Assess link stability on a 1000BaseT Link. Link Monitor will
take 1000 samples of instantaneous (gigabit) remote receiver
status over a 20 second period. Link stability should
approximately correspond to packet flow %.

Utility will measure packet flow from Test Port to Count Port and
report it as %. Assumes both Test Port and Count Port are
connected and have been properly bridged.
test_ slot,port PVA Test Port that will transmit packets. This
parameter must be furnished to the command.
count_ slot,port PVA Test Port that will receive and count
packets. This parameter must be furnished to the command.
pkt_count Count of packets to transmit in a burst. Range is
32K, 128K, 512K, and 1024K. Default is 1024K packets.
pkt_size Size of packets to transmit. Range is 60 to 1512 bytes
in 4 byte increments. Default is 60 bytes.
line Transmit packets at full line rate (96 sec gap). This is the
default rate.
med Transmit packets with 576 nsec packet gap.
slow Transmit packets with 11.006 usec packet gap.

Utility will attempt to flow packets between the Test Port and the
Count Port until packet flow is detected in both directions.
test_ slot,port First PVA Test Port that will transmit and receive
packets. This parameter must be furnished.
count_ slot,port Second PVA Test Port that will transmit and
receive packets. This parameter must be furnished.
timeout Maximum time to wait (in seconds) for bridge
connection to be made. Range is 5 to 60 seconds. Default is
45 seconds.

Assess the ability of the Link Monitor to produce a Link Stability
count that will correlate to packet loss behavior on any given
DUT port. Default Link Rate is 100Base-Tx where many device-
under-test ports may remain linked despite 100% packet loss.
The 100Base-Tx mode evaluates link status response to
impairments that cause both 100% and very high packet loss.
The 1000Base-T mode evaluates the Remote Rx Error indicator
which very commonly will respond in proportion to potential
packet loss.
100 <mdi | mdi-x> Assess if DUT drops link with a severe
impairment that would likely cause 100% packet loss to a
100BaseTx Receiver. Connect according to MDI or MDI-X
polarity. Default is current polarity connection.
1000 Assess DUT’s Remote Receiver Status indicator function.
DUT will be configured to MASTER mode.
