jmx-dev Query: IPv6 Support in JMX SNMP APIs

[Nitin Agrawal]

Thanks Daniel for your response.

It overall does not address my concerns/query. I guess I have not given
sufficient data to you in my query.

We are using javax.management.snmp APIs. In our Management application, we
want to parse the OID data (from a SNMP GET request or a trap), where in
the OID type is an IPAddress and the value can be either IPv4 or IPv6
address. To represent this we are using "?javax.management.snmp.
SnmpIpAddress" class. This supports IPv4 addresses only.

I also checked on the Open DMK site:
https://opendmk.dev.java.net/download/index.html#opendmk-1.0-b02 and
downloaded - opendmk-1.0-b02-src-dual-01-Oct-2007_19-17-46.zip

The class - OpenDMK-src\src\snmp_manager\com\sun\management\snmp
\SnmpIpAddress.java  (Attached here: (See attached file:
SnmpIpAddress.java) ) does not have IPv6 support.

Are you aware of any implementation of such APIs which has got IPv6
support ?

If I see the J2SE JMX API specs @
http://java.sun.com/j2se/1.5.0/docs/guide/jmx/spec.html,
"javax.management.snmp" is not there. Looks like formal support for SNMP
APIs has been dropped by sun.

Hi,

Yes, IPv6 is supported.

You can specify IPv6 addresses in the ACL files, and you can
specify a specific interface to which to bind to (if you want
to bind to an interface which is not the default) using
the com.sun.management.snmp.interface property.

for instance, you can define:
com.sun.management.snmp.interface=::1

See <jdk-install>/jre/lib/management/snmp.acl.template
and <jdk-install>/jre/lib/management/management.properties

Hope this helps,
