Figure 69. Internet Control Message Protocol statistics window.
The
ICMP
tab, as shown in Figure 69, provides the following statistical information
regarding the Internet Control Message Protocol:
•
ICMP messages sent
—This is the total number of ICMP messages sent by the radio.
•
Outgoing messages discarded due to format error
—This is the total number of
ICMP messages sent by radio which were not delivered because of format errors.
•
Destination unreachable messages sent
—This is the total number of destination
unreachable messages sent by the radio. Destination unreachable messages are gener-
ated when the destination address is unreachable.
•
Time exceeded messages sent
—This is the total number of messages sent by the
radio which exceeded their time to live.
•
Parameter problem messages sent
—This is the total number of parameter problem
messages sent. A parameter problem message is sent when an error in the IP header
of a datagram is detected.
•
Source quench messages sent
—This is the total number of source quench messages
sent by the radio. A source quench request is sent to request a reduction in the packet
transmission rate.
•
Redirect messages sent
—This is the total number of redirect messages sent. A
redirect is sent when an alternate route for the datagram is selected.
•
Echo request messages sent
—This is the total number of echo requests sent. An echo
request causes the receiving radio to send an echo reply message back to the originating
radio. Echo requests are typically generated by a “Ping” application.
•
Echo reply messages sent
—This is the total number of echo replies sent. An echo
reply is sent to respond to an echo request. Echo replies are typically generated by a
“Ping” application.
•
Timestamp request messages sent
—This is the total number of timestamp re-
quests sent. A timestamp request causes the radio to send a timestamp reply to the
originating radio.
•
Timestamp reply messages sent
—This is the total number of timestamp replies sent.
A timestamp reply is sent in response to a timestamp request. Timestamp replies and
requests measure the transmission speed of datagrams on a network.
•
Address mask request messages sent
—This is the total number of address mask
requests sent. An address mask request is sent to determine the number of bits in the
subnet mask for the destination’s Ethernet subnet.
•
Address mask reply messages sent
—This is the total number of address mask
responses sent. An address mask response is sent in response to an address mask
request.
