Altocumulustcpdump is for capturing traffic, you could have it store the capture to a mycaptrue,pcap, download the file and open it with wireshark.
options I use most:
-s0: means capture the full packets, by default it truncates them.
-w /var/tmp/outpufile: dont print packets out, store them in binary format in given file
-i vlan_name: the VLAN name to listen on, find list of names with "ifconfig -a" or use "any" for all VLANs.
man tcpdump for more.
