Hello all, I am running the following setup: http://www.sics.se/contiki/tutorials/tutorial-running-contiki-with-uipv6-and-sicslowpan-support-on-the-atmel-raven.html
I am trying to understand the following packet: 16 35.577489 02:12:13:ff:fe:14:15:16 Broadcast IEEE 802.15.4 Data, Dst: Broadcast, Src: 02:12:13:ff:fe:14:15:16, Bad FCS Frame 16 (111 bytes on wire, 111 bytes captured) Ethernet II, Src: MS-NLB-PhysServer-18_13:14:15:16 (02:12:13:14:15:16), Dst: IPv6mcast_00:00:00:01 (33:33:00:00:00:01) IEEE 802.15.4 Data, Dst: Broadcast, Src: 02:12:13:ff:fe:14:15:16, Bad FCS Data (78 bytes) Now, as I understand the setup, the RZ Raven USB bridges 802.15.4 packets to the ethernet. Now when I analyze the frame it tells me that there are three protocols in it (eth:wpan:data). Comparing the above frame with frame 15: 15 35.561236 fe80::12:13ff:fe14:1516 ff02::1 ICMPv6 Router advertisement Comparing IPv6 local link and MAC address I see that the frames are from the RZ Raven USB. The Ethernet II frame is same for the both, while the IPv6 frame in 15 is replaced by a 802.15.4 frame in 16 (Is this the result of 6lowpan? and if I get it right 6lowpan takes place on RZ Raven...) and then there is a frame called data (varying bytes in each 802.15.4 frame) which could be said to correspond to the ICMPv6 frame. What is this data? So, if I get it right the router daemon running on the usb0 interface sends out daemon advertisements which are then encapsulated into 802.15.4 through 6lowpan on the RZ Raven USB - but how come wireshark still sees this packets - for they are no longer generated on the host pc? Also, what is this date protocol in the 802.15.4 packet? Please inform me Rahul Jain ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev@wireshark.org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-requ...@wireshark.org?subject=unsubscribe
