There is presently only one Open Source management
system, that supports IPv6 and SNMPv3. That is Argus.
I like jffnms better ;-), there should be more tools.
From browsing the code:
jffnms has the advantage of being written in PHP so IP
adresses are, as far as I can see, passed as Strings,
leaving all validation to the underlying tools provided by net-
To support IPv6, net-snmp needs an adress prefix
indicating the transport protocol "udp6 or tcp6", which
probably could be passed as part of the node "address".
Problems arise from features such as node discovery -
nmap barely support IPv6 and it will take a long time to
brute-force-scan an entire /64 subnet (mine has about 3
nodes on it!).
Instead, one probably must walk
the "inetCidrForwardingTable", probing all the "nexthops" for
more nodes/networks and pruning redundancies.
So, "First Level" IPv6 support - where User supplies Node
adresses/hostnames is relatively easy (I think); Full support
is harder because literally all netwok probes, NMAP,
SATAN, SARA do not support IPv6 beyond "Ping6".
