Use the Diagnostics menu items to display and configure basic administrative details of
the industrial managed switch. Under System, the following topics are provided to
configure and view the system information:
• Ping
• IPv6 Ping
• Remote IP Ping
• Cable Diagnostics
Ping
The ping and IPv6 ping permit the issuance of ICMP PING packets to troubleshoot IP
connectivity issues. The industrial managed switch transmits ICMP packets, and the
sequence number and roundtrip time are displayed upon reception of a reply.
Cable diagnostics
Cable diagnostics performs tests on copper cables. These functions have the ability to
identify the cable length and operating conditions, and to isolate a variety of common
faults that can occur on the Cat5 twisted-pair cabling. There might be two states, which
are as follows:
• If the link is established on the twisted-pair interface in 1000BASE-T mode, the
cable diagnostics can run without disruption of the link or of any data transfer.
• If the link is established in 100BASE-TX or 10BASE-T, the cable diagnostics cause
the link to drop while the diagnostics are running.
After the diagnostics are finished, the link is re-established and the following functions
are available.
• Coupling between cable pairs
• Cable pair termination
• Cable Length
Ping
The ICMP Ping page allows you to issue ICMP ping packets to troubleshoot IP
connectivity issues.
After clicking
Start
, five ICMP packets are transmitted, and the sequence number and
roundtrip time are displayed upon reception of a reply. The page refreshes
automatically until responses to all packets are received, or until a timeout occurs.
