The tables below describe the fields in the display:
Table 1-11. IP Statistics:
| Field
|
Description
|
Recvd:
|
total
|
The total number of input datagrams received from interfaces, including those received in error.
|
local destination
|
The number of packets received with this router as the destination.
|
header errors
|
The number of input datagrams discarded due to errors in their IP headers, including bad checksums, version number mismatch, other format errors, time-to-live exceeded, errors discovered in processing their IP options, etc.
|
address errors
|
The number of input datagrams discarded because the IP address in their IP header's destination field was not a valid address to be received at this entity.
|
unknown proto
|
The number of packets that were of an unknown protocol type.
|
Sent:
|
generated
|
The total number of IP datagrams which local IP user- protocols (including ICMP) supplied to IP in requests for transmission.
|
forwarded
|
The number of input datagrams for which this entity was not their final IP destination, as a result of which an attempt was made to find a route to forward them to that final destination.
|
fragmented
|
The number of fragmented packets received.
|
fragments created
|
The number of IP datagrams that have been successfully fragmented at this entity.
|
couldn't fragment
|
The number of IP datagrams that have been discarded because they needed to be fragmented at this entity but could not be, e.g., because their Don't Fragment flag was set.
|
Drop:
|
input discards
|
The number of input IP datagrams for which no problems were encountered to prevent their continued processing, but which were discarded (e.g., for lack of buffer space). Note that this counter does not include any datagrams discarded while awaiting reassembly.
|
output discards
|
The number of output IP datagrams for which no problem was encountered to prevent their transmission to their destination, but which were discarded (e.g., for lack of buffer space). Note that this counter would include datagrams counted in ipForwDatagrams if any such packets met this (discretionary) discard criterion.
|
routing discards
|
The number of routing entries which were chosen to be discarded even though they are valid. One possible reason for discarding such an entry could be to free-up buffer space for other routing entries.
|
no route
|
The number of IP datagrams discarded because no route could be found to transmit them to their destination. Note that this counter includes any packets counted in ipForwDatagrams which meet this `no-route' criterion. Note that this includes any datagrams which a host cannot route because all of its default routers are down.
|
Table 1-12. ICMP Statistics
| Field
|
Description
|
Recvd:
|
total
|
The total number of ICMP messages which the entity received. Note that this counter includes all those counted by aviciModuleIcmpInErrors.
|
errors
|
The number of ICMP messages which the entity received but determined as having ICMP-specific errors (bad ICMP checksums, bad length, etc.).
|
unreachable
|
The number of ICMP Destination Unreachable messages received.
|
timeouts
|
The number of ICMP Time Exceeded messages received.
|
param problems
|
The number of ICMP Parameter Problem messages received.
|
quenchs
|
The number of ICMP Source Quench messages received.
|
redirects
|
The number of ICMP Redirect messages received.
|
echos
|
The number of ICMP Echo (request) messages received.
|
echo replies
|
The number of ICMP Echo Reply messages received.
|
timestamps
|
The number of ICMP Timestamp (request) messages received.
|
timestamp replies
|
The number of ICMP Timestamp Reply messages received.
|
addr masks
|
The number of ICMP Address Mask Request messages received.
|
addr mask replies
|
The number of ICMP Address Mask Reply messages received.
|
Sent:
|
total
|
The total number of ICMP messages which this entity attempted to send. Note that this counter includes all those counted by tsrIcmpOutErrors.
|
errors
|
The number of ICMP messages which this entity did not send due to problems discovered within ICMP such as a lack of buffers. This value should not include errors discovered outside the ICMP layer such as the inability of IP to route the resultant datagram.
|
unreachable
|
The number of ICMP Destination Unreachable messages sent.
|
timeouts
|
The number of ICMP Time Exceeded messages sent.
|
param problems
|
The number of ICMP Parameter Problem messages sent.
|
quenchs
|
The number of ICMP Source Quench messages sent.
|
redirects
|
The number of ICMP Redirect messages sent. For a host, this object is always zero, since hosts do not send redirects.
|
echos
|
The number of ICMP Echo (request) messages sent.
|
echo replies
|
The number of ICMP Echo Reply messages sent.
|
timestamps
|
The number of ICMP Timestamp (request) messages sent.
|
timestamp replies
|
The number of ICMP Timestamp Reply messages sent.
|
addr masks
|
The number of ICMP Address Mask Request messages sent.
|
addr mask replies
|
The number of ICMP Address Mask Reply messages sent.

| Field
|
Description
|
Rcvd:
|
total
|
The total number of UDP datagrams delivered to UDP users.

|
Number of times a packet was received that was directed to a port with no application listening.
|
Sent:
|
total
|
The total number of UDP datagrams sent from this entity.
