Extras: ARP Error Message STT Ethernet Connection
Before you begin testing, verify the link.
• Make sure to use the right type of connectors when connecting the test port
to the fiber access point of the network.
• Make sure the laser is turned on.
• Verify the port has a green LINK LED .
• For RJ-45 and SFP ports, if there is no link, then go to the Port window and
set the Auto-Negotiation to Disable (on both units, if applicable). If that
doesn’t work, set Auto-Negotiation to Enable, and configure the test set to
match the DUT settings.
Getting the link up is the most important step in any application, and it can be the
most frustrating. Take the time to ensure the Ethernet tab is properly configured.
You may need to make a change, see what effect that has, make another change,
and so on, until the configuration is correct.
Once you have a green LINK LED, testing is ready to begin.
Troubleshooting an ARP Error Message
The ARP feature makes configuring XTT 5000 easier. ARP takes an IP address and
returns the MAC address of the destination system.
If the unit Failed to resolve the host via ARP, one of two things are likely responsible:
• The IP Address configuration on the test equipment does not match the
network you are testing.
Solution: Enable DHCP if available, or check your network configuration by
pinging your default gateway. If you get no response, your configuration is
invalid.
• The IP Address provided for the destination host is wrong or the host is not on
the network.
Solution: Please check the configuration of the destination host.
From that host, attempt to ping the default gateway to verify network
connectivity.
• XTT-5000 will always ARP for the default gateway. If the ARP fails it will not
affect anything. Requesting the MAC of the default gateway is only required
when sending traffic off of your local Ethernet segment.
Troubleshooting an STT Ethernet Connection
If you are testing using an STT Ethernet there common configuration will cause
problems:
XTT-5000 Throughput --> STT Ethernet
XTT-5000 Throughput <-- STT Ethernet
By default, if you are using Layer 2-4 testing, the XTT-5000 will default to 802.3
framing, and the STT Ethernet will default to Ethernet type II framing.
When sending Throughput (BERT)traffic in both directions, a LOPS error will appear
on one of the units, due to bidirectional traffic.
