Specify the maximum number of ARP cache entries.
Refers to the space available for the IP address table. When you
increase the number of entries, it may cause the table to be relearned
more frequently. Consequently, it will make address space
usage more efficient.
Enable or disable Proxy ARP on the same network. When
enabled, the router will only respond to ARP requests when
the source and target IP address are in the same IP network
and different IP subnets. When disabled, the router will only
respond to ARP requests when the source and target IP address
are in different networks.
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.
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. This count includes invalid
addresses (e.g., 0.0.0.0) and addresses of
unsupported Classes (e.g., Class E). For entities
which are not IP Gateways and therefore do not
forward datagrams, this counter includes datagrams
discarded because the destination address was nota
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.
In entities which do not act as IP Gateways, this
counter will include only those packets which were
Source-Routed via this entity, and the Source-
Route option processing was successful.
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 re-assembly.
The total number of IP datagrams which local IP
user-protocols (including ICMP) supplied to IP in
requests for transmission. Note that this counter
does not include any datagrams counted in
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.
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
datagarms which a host cannot route because all of
its default gateways are down.
The number of failures detected by the IP re-
assembly algorithm (for whatever reason: timed
out, errors, etc). Note that this is not
necessarily a count of discarded IP 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.
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. In some implementations there may be no
types of error which contribute to this counter'svalue.
The interface on which this entry's equivalence
is effective. The interface identified by a
particular value of this index is the same
interface as identified by the same value of
ifIndex. A value of 0 indicates that the entry
is a static entry and does not bind to any interface.
The Status of this entry in the table. Note the
active(1), -- Obviously Active.
notInService(2) -- Interface configured but disabled.
notReady(3), -- Interface NOT configured.
