3 ISUP messages in one packet
Hi.
This packet was captured with Netscout. Wireshark shows 3 ISUP messages in one packet. The source is shown as Rockford MSC but only REL is from that MSC, RLC and CPG are from other MSCs. Sometimes there are even more messages of this sort in one packet. Is this a Wireshark bug?
No. Time Source Destination Protocol Length
1 2019-03-19 10:29:12.321244 Rockford_MSC Schaumburg_MGCF ISUP(ANSI) 250 RLC (CIC 5410) CPG (CIC 1655) REL (CIC 2135)
Providing a link to the capture would help immensely with diagnosis.
Agreed. Or at least a dump of the decode.
I assume the Source & Destination fields are (resolved) IP addresses? Or are they a different field (like OPC and DPC)? I'm wondering if the source (IP) is actually an STP which has bundled these messages together.
