I recently upgraded my 2951 Router from IOS 15.4 to 15.7. Before the upgrade, I woud type
debug serial int
to get the HDLC debug output
and I would get the following debug output
HDLC myseq 6, mineseen 6*, yourseen 7, line up
Now, after the upgrade, I can't get those debug messages anymore. Any ideas?
Solved! Go to Solution.
is it possible that the default encapsulation on serial interfaces has changed from HDLC to PPP in that release ?
