WILL NETVIEW/6000 LOOK AT THE ADDRESS IN THE PDU
ITEM: RTA000028767
QUESTION:
We have a (Internally written) SNMP Proxy agent on a SUN
workstation. This proxy monitors network devices and sends traps to
the network management station. They have had problems (needed coding)
with other net management systems where the trap would be sent from
proxy to the Net Management System and the Proxy would turn red (not the
device with the problem). The cause has to do with the IP header source
field containing the Proxy address (not the agent address). The PDU in
the SNMP record DOES contain the problem agent address. My question is
if we set this same scenario up with Netview/6000, what should we expect
to happen? If the SUN Proxy turns RED (incorrectly), can you tell me
if there is any way for us to (without coding) cause Netview/6000 to get
the address from the PDU record? I vaguely remember that we support
proxy agents, but do those proxy agents have the ability to report traps
to another Netview? If yes, which Netview/6000 supports this (ie, the
currently available one or the recently announced/enhanced Netview?)
---------- ---------- ---------- --------- ---------- ----------
A: In NV/6000, all traps, requests and responses are transmitted in the
form of ASN.1 messages. The structure of the message is defined by
RFC 1157 and is structured as follows: Version Community PDU . The
PDU contains the SNMP request, response or trap data. The PDU and
the message MUST BE encoded according to the ASN.1 rules. If they
are not encoded according to these rules, NV/6000 will not know what
to do with them. The messages from the proxy agent you mention are
probably not adhering to the ASN.1 rules as required by NV/6000
versions 1 AND 2.
So in answer to your question regarding additional coding, it sounds
like coding will be needed to interpret the proxy agent's messages and
PDU data.
