Wireshark is a free and open-source packet analyzer.
It is used for network troubleshooting, analysis, software and communications protocol development, and education.

Following Wireshark Commands are using for Network analysis.
-i <interface> name or idx of interface (def: first non-loopback)
-f <capture filter> packet filter in libpcap filter syntax
-s <snaplen> packet snapshot length (def: 65535)
-p don’t capture in promiscuous mode
-k start capturing immediately (def: do nothing)
-Q quit Wireshark after capturing
-S update packet display when new packets are captured
-l turn on automatic scrolling while -S is in use
-B <buffer size> size of kernel buffer (def: 1MB)
-y <link type> link layer type (def: first appropriate)
-D print list of interfaces and exit
-L print list of link-layer types of iface and exit
–list-time-stamp-types print list of timestamp types for iface and exit
Capture stop conditions:
-c <packet count> stop after n packets (def: infinite)
-a <autostop cond.> … duration:NUM – stop after NUM seconds
filesize:NUM – stop this file after NUM KB
files:NUM – stop after NUM files
-b <ringbuffer opt.> … duration:NUM – switch to next file after NUM secs
filesize:NUM – switch to next file after NUM KB
files:NUM – ringbuffer: replace after NUM files
-A <user>:<password> use RPCAP password authentication
-r <infile> set the filename to read from (no pipes or stdin!)
-R <read filter> packet filter in Wireshark display filter syntax
-n disable all name resolutions (def: all enabled)
-N <name resolve flags> enable specific name resolution(s): “mntdv”
-d <layer_type>==<selector>,<decode_as_protocol> …
“Decode As”, see the man page for details
disable dissection of proto_name
enable dissection of heuristic protocol
disable dissection of heuristic protocol
User interface Wireshark Commands:
-C <config profile> start with specified configuration profile
-Y <display filter> start with the given display filter
-g <packet number> go to specified packet number after “-r”
-J <jump filter> jump to the first packet matching the (display)
-j search backwards for a matching packet after “-J”
-m <font> set the font name used for most text
-t a|ad|d|dd|e|r|u|ud output format of time stamps (def: r: rel. to first)
-u s|hms output format of seconds (def: s: seconds)
-X <key>:<value> eXtension options, see man page for details
-z <statistics> show various statistics, see man page for details
-w <outfile|-> set the output filename (or ‘-‘ for stdout)
Miscellaneous Wireshark Commands:
-h display this help and exit
-v display version info and exit
-P <key:path> persconf:path – personal configuration files
persdata:path – personal data files
-o <name>:<value> … override preference or recent setting
-K <keytab> keytab file to use for kerberos decryption
Logical operators are available for all filtering.
Example: http & ip.src == 192.168.0.1
Management Frame: The frame for the connection between the network device and the client.
Control Frame: Controls the integrity of data traffic between the network device and the client.
Data Frame: The frame on which the original data is transferred.
Only to show the outgoing packets from the management frame.
To show incoming, outgoing packets through control frame.
To show packets transferred over the data frame.
