ICMP Receive/Send Messages window

Access Server Administrators’ Reference Guide 

14 • ICMP

The numbers following the parameters can be a good source of what is happening on the network to point out 
potential problems. Both gateways (routers) and hosts can send ICMP messages.

Total Received/Sent (icmpInMsgs, imcpOutMsgs)

The number of ICMP messages the access server has received/sent. This number also includes ICMP messages 
received/sent which have ICMP specific errors.

w/Errors (icmpInErrors, icmpOutErrors)

The number of ICMP messages which the access server has received/sent but are deemed to be faulty (for 
example, bad ICMP checksums, bad length, or non-routable errors).

Destinations Unreachable (IcmpInDestUnreachs, IcmpOutDestUnreachs)

The number of ICMP destination unreachable messages received/sent. For instance, if the information in a 
gateway’s routing table determines that the network specified in a packet is unreachable, the gateway will send 
back an ICMP message stating that the network is unreachable. The following conditions will send back an 
unreachable message: 

•

The network is unreachable

•

The host is unreachable

•

The protocol is not available to the network

•

The port on the host is unavailable. a specified source route failed

•

A packet must be fragmented (that is, broken up into two or more packets) but the packet was sent anyway 
with instructions not to be fragmented.

Times Exceeded (icmpInTimeExcds, icmpOutTimeExcds)

The number of ICMP time exceeded messages received/sent. Each time a packet passes through a gateway, that 
gateway reduces the time-to-live (TTL) field by one. The default starting number is defined under the IP sec-
tion. If the gateway processing a packet finds that the TTL field is zero it will discard the packet and send the 
ICMP time exceeded message. Time exceeded will also be incremented when a host which is reassembling a 
framented packet cannot complete the reassembly due to missing packets within its time limit. In this case, 
ICMP will discard the packet and send the time exceeded message.

Parameter Problems (icmpInParmProbs, icmpOutParmProbs)

The number of ICMP parameter problem messages received/sent. If while processing a packet, a gateway or 
host finds a problem with one or more of the IP header parameters which prohibits further processing, the gat-
way or host will discard the packet and return an ICMP paramenter problem message. One potential source of 
this problem may be with incorrect or invalid arguments in an option. ICMP sends the parameter problems 
message if the gateway or host has discarded the whole packet.

Source Quenchs (icmpInSrcQuenchs, icmpOutSrcQuenchs)

The number of ICMP source quench messages received/sent. A gateway will discard packets if it cannot allo-
cate the resources, such as buffer space, to process the packet. If a gateway discards the packet, it will send an 
ICMP source quench message back to the sending device. A host may send this messages if packets arrive too 
fast to be processed or if there is network congestion. The source quench message is a request to reduce the rate 
at which the source is sending traffic. If the access server receives a source quench, it will wait for acknowledg-
