Configuring IP Routing (Layer 3)

 

 

 

 

 

Table 7-11.IP Routing Global Statistics (Continued)

 

 

 

 

 

Statistic

Defines the...

 

 

 

 

 

 

IP Reassembly OKs

Number of IP datagrams successfully reassembled.

 

 

 

 

 

 

IP Reassembly Failures

Number of failures detected by the IP re-assembly algorithm

 

 

 

(timeout errors). Note that this is not necessarily a count of

 

 

 

discarded IP fragments since some algorithms can lose track of the

 

 

 

number of fragments by combining them as they are received.

 

 

 

 

 

 

IP Fragmentation OKs

Number of IP datagrams that have been successfully fragmented at

 

 

 

this entity.

 

 

 

 

 

 

IP Fragmentation Failures

Number of IP datagrams that have been discarded because they

 

 

 

needed to be fragmented at this entity but could not be.

 

 

 

 

 

 

IP Fragmentation Creates

Number of IP datagram fragments that have been generated as a

 

 

 

result of fragmentation at this entity.

 

 

 

 

 

 

IP Routing Discards

Number of routing entries that 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.

 

 

 

 

 

 

ICMP In Messages

Total number of ICMP messages that the entity received. Note that

 

 

 

this counter includes all those counted by icmpInErrors.

 

 

 

 

 

 

ICMP In Errors

Number of ICMP messages that the entity received but determined

 

 

 

as having ICMP-specific errors (bad ICMP checksums, bad length).

 

 

 

 

 

 

ICMP In Destination

Number of ICMP Destination Unreachable messages received.

 

 

Unreachables

 

 

 

 

 

 

 

ICMP In Time Exceeds

Number of ICMP Time Exceeded messages received.

 

 

 

 

 

 

ICMP In Parameter Problems

Number of ICMP Parameter Problem messages received.

 

 

 

 

 

 

ICMP In Source Quenchs

Number of ICMP Source Quench messages received.

 

 

 

 

 

 

ICMP In Redirects

Number of ICMP Redirect messages received.

 

 

 

 

 

 

ICMP In Echo Requests

Number of ICMP Echo (request) messages received.

 

 

 

 

 

 

ICMP In Echo Replies

Number of ICMP Echo Reply messages received.

 

 

 

 

 

 

ICMP In Timestamp Requests

Number of ICMP Timestamp (request) messages received.

 

 

 

 

 

 

ICMP In Timestamp Replies

Number of ICMP Timestamp Reply messages received.

 

 

 

 

 

 

ICMP In Address Mask Requests

Number of ICMP Address Mask Request messages received.

 

 

 

 

 

 

ICMP In Address Mask Replies

Number of ICMP Address Mask Reply messages received.

 

 

 

 

 

 

ICMP Out Messages

Total number of ICMP messages that this entity attempted to send.

 

 

 

Note that this counter includes all those counted by

 

 

 

icmpOutErrors.

 

 

 

 

 

 

ICMP Out Errors

Number of ICMP messages that this entity did not send due to

 

 

 

problems discovered within ICMPd 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. In some

 

 

 

implementations, there may be no types of error which contribute

 

 

 

to this counter's value.
