These are the preferences that control how Ethereal dissects the ["iSNS"] protocol.
Desegment iSNS over TCP messages
When you activate this preference, Ethereal will attempt to reassembly all ["iSNS"] PDUs that span multiple TCP segments into one fully reassembled PDU.BR This is useful for example if a specific implementation only sends the ["iSNS"] header and the actual ["iSNS"] command in two separate packets or with servers that respond with massively large replies.BR In order to make this preference take effect, you must also enable reassembly in ["TCP Reassembly"].
-- someone should donate a capture with isns segments spanning multiple segments and link to it as an example from here.
Desegment iSNS over TCP messagesBR
We should sometime later add support to defragment iSNS PDUs that are fragmented at the iSNS layer as well.
