Internet Storage Name Server (iSNS)

iSNS is a protocol to provide discovery, notification, management and configuration of both iSCSI as well as FibreChannel initiators and targets in an IP based SAN.

This protocol is a member of the StorageProtocolFamily.

iSNS is supported by many iSCSI initiator and target implementations but a good management system and interface is still lacking, possibly limiting the full potential of the protocol.

History

iSNS is a protocol defined by the IPS (IP Storage) working group of the IETF.
While it is currently still in draft mode and not an RFC standard, the iSNS protocol has received support from the industry and most/all iSCSI storage vendors today support iSNS.
While the protocol as it is now is not yet a ratified standard/RFC it is semi-widely deployed and it is unlikely that the RFC when it will be published will contain any major changes to the protocol.

Example traffic

XXX - Add example traffic here (as plain text or Wireshark screenshot).

Wireshark

The iSNS dissector is fully functional.

Preference Settings

See iSNS_Preferences

Example capture file

XXX - Add a simple example capture file to the SampleCaptures page and link from here. Keep it short, it's also a good idea to gzip it to make it even smaller, as Wireshark can open gzipped files automatically.

Capture Filter

You cannot directly filter iSNS protocols while capturing. However, if you know the TCP/UDP port used (see above), you can filter on that one.
