5.3 Running Diagnostics
When you set up a new connection, you can verify the link connectivity using PING prior to
sending data.
5.3.1 PING Testing
You can verify network connectivity with another IP device within the subnet by sending a PING
to the IP address for that device. For PING testing instructions, see the 9145ELB NID Software
User’s Manual.
5.4 Loopback Diagnostics
Use Loopbacks to diagnose a fault on the optical link. Loopbacks can be set at any port; once a
port is in loopback mode, data is looped at the physical level though the particular port. When
performing loopback diagnostics, the 9145ELB uses a unique MAC address, designated as the
Loop Test MAC Address, which is displayed on the Loopback Setup Screen (see the 9145ELB
NID Software User’s Manual). When in loopback mode, the 9145ELB filters and discards all
service frames. Only packets with the predefined Loop Test MAC Address are looped back.
The 9145ELB is configurable to swap the origination and destination MAC Addresses and to
recalculate the looped frame's CRC. Test packets are returned to the source according to the
selected options.
To display current loopback status, configure address swapping and CRC recalculation options,
see the 9145ELB NID Software User’s Manual.
