100 ICMP Receive/Send Messages window
Redirects (icmpInRedirects, icmpOutRedirects)
The number of ICMP redirect messages received/sent. A gateway sends a redirect message to a host if the net-
work gateways find a shorter route to the destination through another gateway.
Echos (icmpInEchos, icmpOutEchos)
The number of ICMP echo request messages received/send. The ICMP echo is used whenever one uses the
diagnostic tool ping. Ping is used to test connectivity with a remote host by sending regular ICMP echo
request packets and then waiting for a reply. Received echos (icmpInEchos) will increment when the DACS is
pinged.
Echo Replys (icmpInReps, icmpOutReps)
The number of ICMP echo reply messages received/sent. An echo reply is a response to an echo request. Send
echos (icmpOutEchos) will increment when the DACS sends an echo reply message in response to a ping.
Time Stamps (icmpInTimestamps, icmpInTimestamps)
The number of ICMP time stamp messages received/sent. Time stamp and time stamp replies were originally
designed into the ICMP facility to allow network clock synchronization. Subsequently, a new protocol—Net-
work time protocol (NTP) has taken over this function. Normally, this number will be zero.
Time Stamp Replys (icmpInTimestampsReps) (icmpOutTimestampsReps)
The number of ICMP timestamp reply messages received/sent. This message is part of a time stamp (see “Time
Stamps (icmpInTimestamps, icmpInTimestamps)”) request. Normally, this number will be zero.
Address Mask Requests (icmpInAddrMasks) (icmpOutAddrMasks)
The number of ICMP address mask request messages received/sent. this message is generally used for diskless
workstations which use this request at boot time to obtain their subnet mask. This number will increase if there
are hosts on the network which broadcast these requests.
Address Mask Replys (icmpInAddrMasksReps) (icmpOutAddrMasksReps)
The number of ICMP address mask reply messages received/sent. Normally, this number will be zero.
