Some basic filters for analysing wireshark logs in case of IEC protocols
==Wireshark and IEC60870-5-104, IEC61850==
Some basic filters and examples for analysing wireshark logs in case of IEC protocols.<br />
 
 
==IEC60870-5-104==
==IEC60870-5-104==
If you use some port other than 2404, then Wireshark will not automatically detect the correct protocol.
In this case,
#select a IEC104 packet from the captured packets list,
#go to Analyse -> Decode as
#In the transport tab,  select TCP : both ports and protocol 104apci<br />

NOTE: when 61850 capture is recorded after the protocol has initialised (not from the beginning), then Wireshark will not automatically detect the protocol as MMS.
However, it is possible to change the "PRES" to "MMS" using the Wireshark menus:
<pre>Go to Edit->preferences->protocol->PRES and edit the users context tale
enter context = 3 and OID = 1.0.9506.2.3 and your trace will be dissected as MMS.</pre>

===61850 Wireshark capture side-by-side with console.log===
Case study:
GW6e connects with Vamp255 device over IEC61850.
RTU is configured to use BRCB3 and DS1.
RTU initializes communication, sends GI, executes a SBO command and receives a report (spontaneous) about change of LN state.
Pcap capture file is accessible from this link: http://phobos.martem.ee/shr/61850_example_log/tcplog61850.pcap

About ResvTms: Indicates the reservation of a control block by a peculiar client. Read http://tissue.iec61850.com/tissue/300
About configuring Vamp devices regarding ResvTms:

https://m.vamp.fi/dmsdocument/204
ResvTms included in BRCBs = specifies whether “ResvTms”-attribute is included in
the BRCBs or not (this is actually an extension from Tissue 453 and Edition 2 and
should be set to “No” if the client system does not support this).
NOTE: Martem supports this extension

Wireshark and IEC60870-5-104, IEC61850

Some basic filters and examples for analysing wireshark logs in case of IEC protocols.


IEC60870-5-104

If you use some port other than 2404, then Wireshark will not automatically detect the correct protocol. In this case,

  1. select a IEC104 packet from the captured packets list,
  2. go to Analyse -> Decode as
  3. In the transport tab, select TCP : both ports and protocol 104apci

Dispaly packages with TCP length>0 (no ack messages) 

tcp.len>0

IEC104 packages 

104apci

IEC104 packages (without testframes, S-packets etc) 

104asdu

Packets involving 192.168.0.111 

ip.addr==192.168.0.111

TCP port 2404 

tcp.port==2404

Information object address 401 

 104asdu.ioa == 401

Spontaneous events (COT==3) 

104asdu.causetx == 3

Command messages (COT 6, 7, 10) 

104asdu.causetx == 6  //Activation
104asdu.causetx == 7   //Confirmation
104asdu.causetx == 10   //Termination

Testframe messages 

104apci.utype == 0x10   //Activation
104apci.utype == 0x20   //Confirmation

S-Type messages 

104apci.type == 0x01

General Interrogation commands 

104asdu.typeid == 100   //Global, Group1...Group16
104asdu.qoi == 20       //Global
104asdu.qoi == 21       //Group1
104asdu.qoi == 35       //Group15
                        Do not use Group 16 GI with Martem devices. This is reserved.

Clock syncronisation commands 

104asdu.typeid == 103

Show IEC104 measurements with value "0" 

IEC104asdu.normval == 0

IEC61850 and Wireshark basics

MMS: Manufacturing Message Specification GOOSE: Generic Object Oriented Substation Events

NOTE: when 61850 capture is recorded after the protocol has initialised (not from the beginning), then Wireshark will not automatically detect the protocol as MMS. However, it is possible to change the "PRES" to "MMS" using the Wireshark menus: 

Go to Edit->preferences->protocol->PRES and edit the users context tale
enter context = 3 and OID = 1.0.9506.2.3 and your trace will be dissected as MMS.


Filter IEC61850 packets 

 mms

Display packets involving TCP port 102 

tcp.port==102

Display messages containing domain ID "VampRelay" 

mms.domainId == "VampRelay"

Display messages containing item ID "VI1GGIO137$CO$SPCSO$Oper" (VI1 control command) 

mms.itemId == "VI1GGIO137$CO$SPCSO$Oper"

Display messages containing control commands (Service request 5 = write) 

mms.confirmedServiceRequest == 5

Dispaly packets containing message "success" (response to command message) 

mms.Write_Response_item == 1

61850 Wireshark capture side-by-side with console.log

Case study:

GW6e connects with Vamp255 device over IEC61850.

RTU is configured to use BRCB3 and DS1.

RTU initializes communication, sends GI, executes a SBO command and receives a report (spontaneous) about change of LN state.

Pcap capture file is accessible from this link: http://phobos.martem.ee/shr/61850_example_log/tcplog61850.pcap


Summary:

Step1. TCP-handshake (3-way handshake)

Step2. COTP: connect request (CR) and connect confirmation (CC)

Step3. MMS CONNECT and ACCEPT

Step4. getNamedVariableListAttributes (domainId: 255Relay; itemId: LLN0$DS1)

Step5. getNameList

Step6. Check LLN0$BR$brcbEV103$RptEna item

Step7. Enable and configure BRCB3

Step8. Verify that BRCB3 is enabled

Step9. Verify that BRCB3 is configured correctly

Step10. Read ConfRev parameter

Step11. Read getVariableAccessAttributes for all the configured objects, one by one

Step12. Send GI

Step13. Send control command

Step14. Receive spontaneous (unconfirmed PDU) event for state change


Step1. RTU starts connecting to the IED with a TCP-handshake (3-way handshake): 

6	2015-08-06 10:29:59.943110	10.0.0.104	172.16.1.3	TCP	74	56642→102 [SYN] Seq=0 Win=5840 Len=0 MSS=1460 SACK_PERM=1 TSval=2023 TSecr=0 WS=64
7	2015-08-06 10:30:02.443727	172.16.1.3	10.0.0.104	TCP	60	102→56642 [SYN, ACK] Seq=0 Ack=1 Win=2047 Len=0
8	2015-08-06 10:30:02.443952	10.0.0.104	172.16.1.3	TCP	54	56642→102 [ACK] Seq=1 Ack=1 Win=5840 Len=0

Step2. COTP (Connection Oriented Transport Protocol) connect request (CR) and connect confirmation (CC): 

9	2015-08-06 10:30:02.444413	10.0.0.104	172.16.1.3	COTP	76	CR TPDU src-ref: 0x0001 dst-ref: 0x0000 (PDU Type: CR Connect Request (0x0e))
10	2015-08-06 10:30:02.539805	172.16.1.3	10.0.0.104	TCP	60	102→56642 [ACK] Seq=1 Ack=23 Win=2025 Len=0
11	2015-08-06 10:30:02.739731	172.16.1.3	10.0.0.104	COTP	76	CC TPDU src-ref: 0x0002 dst-ref: 0x0001 (PDU Type: CC Connect Confirm (0x0d))

Read more about COTP: https://wiki.wireshark.org/COTP

Step 3. MMS CONNECT and ACCEPT 

 
13	2015-08-06 10:30:02.740616	10.0.0.104	172.16.1.3	MMS	244	initiate-RequestPDU (ISO 8327-1 OSI Session Protocol -> SPDU Type: CONNECT (CN) SPDU (13))
15	2015-08-06 10:30:03.225870	172.16.1.3	10.0.0.104	MMS	212	initiate-ResponsePDU (ISO 8327-1 OSI Session Protocol -> SPDU Type: ACCEPT (AC) SPDU (14))

After successful MMS connection, RTU will write to console.log: 

 
2015-08-06 10:30:03.227 [INFO] Gateway.Port14 - ASSOCIATE ok for 172.16.1.3 0

Step 4. RTU sends a request for getNamedVariableListAttributes (domainId: 255Relay; itemId: LLN0$DS1) 

 
16	2015-08-06 10:30:03.231791	10.0.0.104	172.16.1.3	MMS	103	confirmed-RequestPDU ( MMS -> confirmedServiceRequest: getNamedVariableListAttributes (12)
19	2015-08-06 10:30:03.606017	172.16.1.3	10.0.0.104	MMS	316	confirmed-ResponsePDU ( MMS-> confirmedServiceResponse: getNamedVariableListAttributes (12) (itemId: I3pMMXU1$MX$A$phsA, I3pMMXU1$MX$A$phsB....up to SIpMMXU23$MX$A )

The response contains all the item ID-s from 255Relay that are in dataset LLN0$DS1. The RTU logs this information as follows:

Step 5. RTU sends a request for getNameList (IEC61850 GetDataSetDirectory) 

 
21	2015-08-06 10:30:04.404171	10.0.0.104	172.16.1.3	MMS	90	confirmed-RequestPDU ( MMS -> confirmedServiceRequest: getNameList (1))
23	2015-08-06 10:30:04.891920	172.16.1.3	10.0.0.104	MMS	96	confirmed-ResponsePDU ( MMS -> confirmedServiceResponse: getNameList (1))

Step 6. RTU reads the LLN0$BR$brcbEV103$RptEna and LLN0$BR$brcbEV103$ResvTms items: 

 
25	2015-08-06 10:30:05.956536	10.0.0.104	172.16.1.3	MMS	130	confirmed-RequestPDU  ( MMS -> confirmedServiceRequest: read (4) (domainId: 255Relay, itemId: LLN0$BR$brcbEV103$RptEna))
27	2015-08-06 10:30:06.315874	172.16.1.3	10.0.0.104	MMS	86	confirmed-ResponsePDU ( MMS -> confirmedServiceResponse: read (4); listOfAccessResult: 1 item; AccessResult: success (1), FALSE)

The response states that BRCB3 is not enabled. Next, RTU reads the LLN0$BR$brcbEV103$ResvTms parameter: 

29	2015-08-06 10:30:06.317941	10.0.0.104	172.16.1.3	MMS	131	confirmed-RequestPDU ( MMS -> confirmedServiceRequest: read (4) domainId: 255Relay; itemId: LLN0$BR$brcbEV103$ResvTms)
31	2015-08-06 10:30:06.747774	172.16.1.3	10.0.0.104	MMS	86	confirmed-ResponsePDU ( MMS -> confirmedServiceResponse: read (4) (AccessResult: success (1), integer: 0))

About ResvTms: Indicates the reservation of a control block by a peculiar client. Read http://tissue.iec61850.com/tissue/300 About configuring Vamp devices regarding ResvTms: 

https://m.vamp.fi/dmsdocument/204
ResvTms included in BRCBs = specifies whether “ResvTms”-attribute is included in
the BRCBs or not (this is actually an extension from Tissue 453 and Edition 2 and
should be set to “No” if the client system does not support this).
NOTE: Martem supports this extension

BTW, in the mean time, RTU has changed the "link" status of the device as "connected" 

 
2015-08-06 10:30:04.907 [INFO] Gateway.Port14 - Enable 1 RCB's
2015-08-06 10:30:04.912 [DEBUG] Gateway.Port14 - StatusDi: connected

2015-08-06 10:30:04.919 [INFO] Gateway.Port14 - Refresh all values

Step 7. RTU sends a write request (with new values) for BRCB3 items (see console.log for details): 

32	2015-08-06 10:30:06.754924	10.0.0.104	172.16.1.3	MMS	431	confirmed-RequestPDU  ( MMS -> confirmedServiceRequest: write (5) (domainId: 255Relay; Item ID-s and values...)
34	2015-08-06 10:30:07.195910	172.16.1.3	10.0.0.104	MMS	96	confirmed-ResponsePDU ( MMS -> confirmedServiceResponse: write (5) (write: 7 items; Write-Response item: success (1) for all 7 writes))

RTU console.log: 

2015-08-06 10:30:06.749 [INFO] Gateway.Port14 - RcbEnable: mms write 255Relay/LLN0$BR$brcbEV103$ResvTms=2

2015-08-06 10:30:06.753 [INFO] Gateway.Port14 - RcbEnable: mms write 255Relay/LLN0$BR$brcbEV103$GI=T

Step8. RTU reads the RptEna item again: 

 
35	2015-08-06 10:30:07.197131	10.0.0.104	172.16.1.3	MMS	130	confirmed-RequestPDU (MMS -> confirmedServiceRequest: read (4) (itemId: LLN0$BR$brcbEV103$RptEna)
42	2015-08-06 10:30:07.720025	172.16.1.3	10.0.0.104	MMS	86	confirmed-ResponsePDU (MMS -> confirmedServiceResponse: read (4) (AccessResult: success (1), TRUE)

This time RCB is enabled and RTU then writes to the console.log: 

 
2015-08-06 10:30:07.721 [INFO] Gateway.Port14 - RcbEnable: report enable ok 255Relay/LLN0$BR$brcbEV103

Step9. RTU reads parameters of BRCB3 (see console.log for details) 

 
44	2015-08-06 10:30:07.727357	10.0.0.104	172.16.1.3	MMS	398	confirmed-RequestPDU (MMS -> confirmedServiceRequest: read (4) (variableAccessSpecificatn: listOfVariable (0); listOfVariable: 7 items;)
46	2015-08-06 10:30:08.135870	172.16.1.3	10.0.0.104	MMS	132	confirmed-ResponsePDU (MMS -> confirmedServiceResponse: read (4) (listOfAccessResult: 7 items; AccessResult: success (1); values in console.log)

The following data is received: 

 
2015-08-06 10:30:07.722 [INFO] Gateway.Port14 - RcbEnable: mms read 255Relay/LLN0$BR$brcbEV103$RptID

2015-08-06 10:30:07.724 [INFO] Gateway.Port14 - RcbEnable: mms read 255Relay/LLN0$BR$brcbEV103$ConfRev
2015-08-06 10:30:07.725 [INFO] Gateway.Port14 - RcbEnable: mms read 255Relay/LLN0$BR$brcbEV103$EntryID
2015-08-06 10:30:08.174 [INFO] Gateway.Port14 - RcbEnable: RCB attribute values: "","255Relay/LLN0$DS1",[0111111111],[011101],+60000,+2053,'0000000000000009'
0-NOT used
1-data change=TRUE
1-quality change =TRUE
1-data update=TRUE
0-integrity = FALSE
1-GI enable =TRUE

Step10. RTU reads ConfRev parameter again (i.e to get it if RCB enabling fails): 

 
48	2015-08-06 10:30:08.175876	10.0.0.104	172.16.1.3	MMS	131	confirmed-RequestPDU (MMS -> confirmedServiceRequest: read (4) (itemId: LLN0$BR$brcbEV103$ConfRev))
50	2015-08-06 10:30:08.593893	172.16.1.3	10.0.0.104	MMS	88	confirmed-ResponsePDU (MMS -> confirmedServiceResponse: read (4) (AccessResult: success (1); unsigned: 2053))

And outputs to console.log: 

 
2015-08-06 10:30:08.595 [INFO] Gateway.Port14 - RcbEnable: ConfRev=2053
2015-08-06 10:30:08.596 [DEBUG] Gateway.Port14 - rptId=255Relay/LLN0$BR$brcbEV103,confRev=2053,datSet=255Relay/LLN0$DS1,entryId='0000000000000009',time=08/06/2015_07:30:06.955

Step11. RTU requests getVariableAccessAttributes for all the configured objects, one by one : 

 
52	2015-08-06 10:30:08.634159	10.0.0.104	172.16.1.3	MMS	115	confirmed-RequestPDU (MMS -> confirmedServiceRequest: getVariableAccessAttributes (6); domainId: 255Relay; itemId: I3pMMXU1$MX$A$phsA)
54	2015-08-06 10:30:09.055958	172.16.1.3	10.0.0.104	MMS	152	confirmed-ResponsePDU (MMS -> confirmedServiceResponse: getVariableAccessAttributes (6); components: 3 items;)

The results are available in console.log:

Step12. Send GI 

 
2015-08-06 10:30:18.743 [INFO] Gateway.Port14 - Send GI, 255Relay/LLN0.brcbEV103

In MMS, the RTU writes the LLN0$BR$brcbEV103$GI item to value 1, receives a response (success) and finally receives an "unconfirmed PDU" containing all the items that respond to GI in that dataset (in my case, 72 items)

THIS IS GI RESPONSE WITH ALL VARIABLES AND PARAMETERS)

The information gathered from GI response looks like this in the console.log:
