I have a dissector plugin that is registered with port A. Once in a while,
this dissector is not kicking in. It looks like it "overpowered" by a dissector with registered port 3503 (lsp-ping). It looks like port 3503 is defined inĀ epan\dissectors\packet-mpls-echo.c(39):#define UDP_PORT_MPLS_ECHO 3503. Can somebody suggest how to avoid this trap? A couple of quick suggestions: 1) Change the other application/protocol so it avoids using any registered ports. See http://www.iana.org/assignments/port-numbers 2) Although this seems rather silly to me, you could change the MPLS Echo dissector's registered port preference via Edit -> Preferences -> Protocols -> MPLS Echo -> MPLS Echo UDP Port. 3) You can try disabling Wireshark's MPLS Echo dissector altogether via Analyze -> Enabled Protocols -> MPLS Echo. That other application/protocol might just end up using another registered port though, so if you choose either 2 or 3 above, you could end up running into this again with another one of Wireshark's dissectors. ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
