broadcast address.
To configure the settings and ping a host on the network:
1.
Select
Maintenance > Troubleshooting > Ping
.
2.
In the IP Address/Host Name field, specify the IP address or the host name of the station
you want the switch to ping.
The initial value is blank. This information is not retained across a power cycle. The
maximum number of characters in a name is 160.
3.
Optionally, configure the following settings:
•
In the Count field, specify the number of pings to send. The valid range is 1–15.
•
In the Interval (secs) field, specify the number of seconds between pings sent. The
valid range is 1–60.
•
In the Size field, specify the size of the ping (ICMP) packet to send. The valid range is
0–65507.
•
The Results field displays the result after the switch sends a ping request to the
specified address.
4.
Click
APPLY
to send the ping. The switch sends the number of pings specified in the Count
field, and the results are displayed in the Results field.
•
If a reply to the ping is received, you see “Reply From IP/Host: icmp_seq = 0. time =
xx usec. Tx = x, Rx = x Min/Max/Avg RTT = x/x/x msec.”
•
If a reply to the ping is not received, you see “Reply From IP/Host: Destination
Unreachable. Tx = x, Rx = 0 Min/Max/Avg RTT = 0/0/0 msec.”
