TRAP LOG HELP
SNMP trap messages are used to report significant TCP/IP events.
The SNMPLOG NLM processes trap messages sent to the local TCP/IP
node and writes them to disk. This screen displays those traps,
with the most recent traps listed first. Upon exit from this
display, the trap log file can either be deleted or preserved.
The following fields are displayed for each trap message:
Trap Type
Indicates the event type triggering each trap message. Six trap
types are defined to report TCP/IP coldstart, warmstart, link
down, link up, request authentication failure, and egp neighbor
loss. A seventh trap type is used to report enterprise-specific
(vendor-specific) events. Enterprise-specific event codes are displayed following the trap type indication.

TRAP LOG HELP
Hostname field
Indicates the hostname or IP address of the TCP/IP node
which issued each trap message. Symbolic hostnames are in
net\tcp\hosts file. IP addresses are displayed in dotted
decimal notation. The tab key toggles between symbolic name
and address display formats.
Timestamp field
Indicates the date and time each trap message was received and
processed by the local TCP/IP node.

Page 1 of 1
COMMUNITY NAME HELP
Specifies the community name included in each SNMP request message.
This name is used by the SNMP agent to determine the type of
management object access which should be granted. The LAN WorkPlace
SNMP agent community name defaults are "public" for read-only access
and "disabled" for read/write access. Community names can be changed
at SNMP agent load time. Other SNMP agent implementations may require
different community names.
The community name must match the name established for the SNMP agent
at the selected target host. A community name mismatch causes the
remote SNMP agent at the target to discard LWPCON request messages.
When this occurs the summary display shows "unknown" for all
statistic values and "HOST UNAVAILABLE" in the lower right corner.
INTERFACE HELP
The interface table displays the network interfaces supported by
the selected TCP/IP host system. Each entry contains a textual
description of the interface type, the interface number and the

entities which are not IP Gateways and therefore do
not forward datagrams, this statistical object
includes datagrams discarded because the destination address was not a local address.
ipForwDatagrams HELP

via this entity, and for which the source-route
processing option was successful.
ipInUnknownProtos HELP
The number of locally addressed datagrams received
successfully but discarded because of an unknown or
unsupported protocol.

The number of datagrams given to IP for transmission.
This statistical object does not include any datagrams
counted in ipForwDatagrams.
ipOutDiscards HELP
The number of output IP datagrams for which no
problem was encountered to prevent their transmission
to their destination, but which were discarded. One
reason to discard such a packet would be lack of
buffer space. This statistical object includes
datagrams counted in ipForwDatagrams if any such
packets met this discard criterion.
ipOutNoRoutes HELP
The number of IP datagrams discarded because no route
could be found to transmit them to their destination.

The number of IP datagrams that have been discarded
because they needed to be fragmented at this entity
but could not be because their "don't fragment" flag
was set.
ipFragCreats HELP
The number of IP datagram fragments that have been
generated as a result of fragmentation at this entity.
TCP/IP STATISTICS HELP
