capture tunnel packets

when I start my AICCU 'tcpdump icmp' does not give any response while pinging. Can anybody give a tcpdump expression to capture tunnel packets only.
capture tunnel packets
It depends on what you want to see, but likely you are looking for:
tcpdump -i sixxs -Xns 0 icmp6
That shows only ICMPv6 (icmp6) on the interface called 'sixxs' (depending on what your tunnel interface is called).
Note that "icmp" is IPv4 ICMP, while "icmp6" is ICMPv6 aka the ICMP for IPv6.
Of course you should also check that your tunnel actually works on the IPv4 layer by dumping there.
