Internet Stogare Name Server (iSNS)

iSNS is a protocol to provide discovery, notification, management and configuration of both ["iSCSI"] as well as ["Fibre Channel"] initiators and targets in an IP based SAN.BR 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.


iSNS is a protocol defined by the [ IPS] (IP Storage) working group of the IETF.BR 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.BR While the protocol as it is now is not yet a ratified standard/RFC it is semiwidely 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 Ethereal screenshot).


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 Ethereal can open gzipped files automatically.

Display Filter

A complete list of iSNS display filter fields can be found in the [ display filter reference]

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.
