Question on filtering zenoh discovery traffic

[justin-kel]

Wireshark Version: 4.2.5
Zenoh dissector: release-0.11.0-dev
Zenoh version: 0.11.0-rc.2

I would like to ask how to use the zenoh dissector to filter and display zenoh discovery related traffic, what filters I should apply?

Thank you!

Hi @justin-kel!

The default UDP port for Zenoh scouting is 7446. To change the listening port for UDP, go to "Edit > Preferences > Protocols > Zenoh > UDP Port". We should change the default UDP port to 7446 for convenience.

EDIT: The decoding of scouting messages seems not to work. #25 I will fix it later.

Hi @YuanYuYuan,

Thank you so much for your prompt reply!

I am actually trying to compare zenoh discovery to DDS discovery traffic, similar to what was done in the blog post here

Is it fair to directly compare the total bytes for all traffic on the zenoh scouting port, with all SEDP and SPDP traffic in DDS? Or are there other things in Zenoh that I should consider as well?

Thanks again!
