Select Diagnostics
Select one or more diagnostic methods you want
to run, or select
All
to run them all.
ARP Table
Address Resolution Protocol (ARP) table used to
view the IP address-to-hardware address
mapping.
Netstat
Displays network connections. If you select the
checkbox, select
a protocol or select
All
for both
protocols to control the output of the Netstat
report.
Host Lookup
If you enter a host name in the corresponding
Hostname
field, verifies that the SLC can resolve
the host name into an IP address (if DNS is
enabled).
Ping
If you enter a host name in the corresponding
Hostname
field, verifies that the host is up and
running.
Send Packet
This option sends an Ethernet packet out one of
the Ethernet ports, mainly as a network
connectivity test.
Enter the following:
Protocol:
Select the type of packet to send.
Hostname:
Specify a host name or IPaddress of
the host to send the packet to.
Port:
Specify a
TCP
or
UDP
port number of the
host to send the packet to.
String:
Enter a set of up to 64 characters. The
string is encapsulated in the packet (so you could
use a network sniffer to track the packet and, by
looking at its contents, verify that it was sent).
Count:
The count is the number of times the string
is sent.
For UDP, the number of times the string is sent is
equal to the number of packets sent.
For TCP, the number of times the string is sent
may (or may not) be equal to the number of
packets sent, because TCP controls how data is
packetized and sent out.
