Table 33: Show IPv6 Statistics - display description

Field

Description

IPv6 Statistics

IPv6 Received

Total

The total number of input datagrams received by the interface,

including those received in error.

Header Errors

The number of input datagrams discarded due to errors in their

IPv6 headers, including version number mismatch, other format

errors, hop count exceeded, IPv6 options, etc.

Too Big Errors

The number of input datagrams that could not be forwarded

because their size exceeded the link MTU of outgoing interface.

No Routes

The number of input datagrams discarded because no route could

be found to transmit them to their destination.

Address Errors

The number of input datagrams discarded because the IPv6

address in their IPv6 header's destination field was not a valid

address to be received at this entity. This count includes invalid

addresses (e.g., ::0) and unsupported addresses (e.g., addresses

with unallocated prefixes). For entities which are not IPv6 routers

and therefore do not forward datagrams, this counter includes

datagrams discarded because the destination address was not a

local address.

Unknown Protocols

The number of locally-addressed datagrams received successfully

but discarded because of an unknown or unsupported protocol.

This counter is incremented at the interface to which these

datagrams were addressed which might not be necessarily the

input interface for some of the datagrams.

Truncated Packets

The number of input datagrams discarded because datagram

frame didn't carry enough data.

Discards

The number of input IPv6 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

re-assembly.

Delivers

The total number of datagrams successfully delivered to IPv6

user-protocols (including ICMP). This counter is incremented at

the interface to which these datagrams were addressed which

might not be necessarily the input interface for some of the

datagrams.

Reassembly Request

Datagrams

The number of IPv6 fragments received which needed to be

reassembled at this interface. Note that this counter is increment

ed at the interface to which these fragments were addressed

which might not be necessarily the input interface for some of the

fragments.

Reassembled Succeeded

The number of IPv6 datagrams successfully reassembled. Note

that this counter is incremented at the interface to which these

datagrams were addressed which might not be necessarily the

input interface for some of the fragments.

Reassembled Failed

The number of failures detected by the IPv6 re-assembly

algorithm (for whatever reason: timed out, errors, etc.). Note that

this is not necessarily a count of discarded IPv6 fragments since

some algorithms (notably the algorithm in RFC 815) can lose

track of the number of fragments by combining them as they are

received. This counter is incremented at the interface to which

these fragments were addressed which might not be necessarily

the input interface for some of the fragments.
