hmmmm actually I am running 12.1.19. Can't imagine it is gone though.
Strange!! I was informed the reverse path was
suppose to be replaced with the source!!
Unfortunately I can't upgrade at this time as it is on it's own net with no
ftp/tftp.
Sorry,
mike

Well...
Due to CDP bug I just upgraded a test 3550 EMI switch from 12.1(19)EA1
to 12.1(20)EA2. To my surprise, all of my interface configuration lines
"ip verify unicast reverse-path" are gone and the command is no longer
recognized.
I've searched each of the release notes incrementally from 12.1(19)EA1
through 12.1(20)EA2 and there is no mention of this command being
removed or the functionality replaced.
I've just checked the command references and it's not listed in either
version, but it was available in 12.1(19)EA1.
Any run into this before or have any ideas?
