![]() However, the "& 0xffffff00" expression masks off the fourth byte. ![]() Unfortunately, you want to examine three bytes, but you can only put 1, 2, or 4 after the colon, so three is not a valid value. The master list of display filter protocol fields can be found in the display filter reference. Stable Release: 4.0. Host name filter: ip.host hostname: MAC address filter: eth. Download Download Wireshark The current stable release of Wireshark is 4.0.4.I know its ID in the first 24bits of the MAC address, such as AA:BB:CC:xx:xx:xx. I want to filter all traffic from a particular WiFi chip manufacture. The WiFi network interface is configured to capture in monitor mode and Wireshark in promiscuous mode. ![]() The basics and the syntax of the display filters are described in the User's Guide. Wireshark broadcast filter: eth.dst ff:ff:ff:ff:ff:ff. The station is a Ubuntu laptop with a TP-Link TP-WN722M WiFi adaptor. In the capture filter expressions "ether" and "ether", 0 and 6 are the starting bytes for the destination MAC address field and the source MAC address field respectively, and 4 is the number of bytes to examine. Wireshark uses display filters for general packet filtering while viewing and for its ColoringRules. (ether & 0xffffff00 = 0x000c2200) or (ether & 0xffffff00 = 0x000c2200) Wireshark is the world’s foremost and widely-used network protocol analyzer. ![]() To capture packets where either the source or destination MAC address starts with 00:0C:22: Common Filtering Commands Wireshark multicast filter, (eth.dst0 & 1) Host name filter, ip.host hostname MAC address filter, eth.addr. Disabling MAC address resolution can be helpful for applications such as live scanning a busy network where performance could be affected by the need to resolve. But if you know where in the MAC address field those three bytes will be, you can use a byte-offset capture filter. You probably can't create a capture filter for MAC addresses containing 00:0C:22 anywhere in the MAC address fields. Wiresharkand TSharkshare a powerful filter engine that helps remove the noise from a packet trace and lets you see only the packets that interest you. You said, "I want to capture all traffic from devices with MAC address containing 00:0C:22." You may also use Wireshark capture and analysis tool.
