4.8.11 Ping
The Device Management > Ping page is used to send ICMP echo request packets to another node on the network.
Host Name/IP Address IP address or alias of the host.
Probe Count Number of packets to send. (Range: 1-16)
Packet Size Number of bytes in a packet. (Range: 32-512 bytes) The actual packet size will be eight bytes larger than
the size specified because the switch adds header information.
4.8.12 Trace Route
The Device Management > Trace Route page is used to show the route packets take to the specified destination.
Destination IP Address Alias or IPv4/IPv6 address of the host.
IPv4 Max Failures The maximum number of failures before which the trace route is terminated. (Fixed: 5)
IPv6 Max Failures The maximum number of failures before which the trace route is terminated. (Range: 1-255; Default: 5)
Command Usage
Use the trace route function to determine the path taken to reach a specified destination.
A trace terminates when the destination responds, when the maximum timeout (TTL) is exceeded, or the maximum number of
hops is exceeded.
The trace route function first sends probe datagrams with the TTL value set at one. This causes the first router to discard the
datagram and return an error message. The trace function then sends several probe messages at each subsequent TTL level
and displays the round-trip time for each message. Not all devices respond correctly to probes by returning an “ICMP port
unreachable” message. If the timer goes off before a response is returned, the trace function prints a series of asterisks and the
“Request Timed Out” message. A long sequence of these messages, terminating only when the maximum timeout has been
reached, may indicate this problem with the target device.
The same link-local address may be used by different interfaces/nodes in different zones (RFC 4007). Therefore, when
specifying a link-local address, include zone-id information indicating the VLAN identifier after the % delimiter. For example,
