RE: DLSW direct encaps

All,

Attached is the debug output using IETF encaps and DLSW Direct:

00:21:06: Serial0(i): dlci 25(0x491), pkt encaps 0x0300 0x8000 0x0000
0x1995(ILLEGAL), datagramsize 405

I have not been able to come up with exactly what caused this, however I
will put a frame analyser back on and see what I can find. Also have a TAC
case regarding this - no response yet.

When I change the encaps to Cisco this goes away!

Cheers,

                Hi, Jason

                Thanks for sharing your finding.
                It's very interesting. You save me my own would-be
frustrating days.
                Those undocumented or poorly documented features are always
driving me crazy.

                Can I share the debug output of this?
                Thanks

                Jaeheon

It works fine
