Abnormal console display when IPSec/Isakmp debug is on

IE_R1#sh debugging

Cryptographic Subsystem:

Crypto ISAKMP debugging is on

Crypto IPSEC debugging is on

IE_R1#

1d03h:

IPSEC(encapsulate): encaps area too small, moving to new buffer: idbtype 0, encaps_size 84, header size 36, avail 84

IPSEC(encapsulate): encaps area too small, moving to new buffer: idbtype 0, encaps_size 84, header size 36, avail 84

IPSec works fine in my case, but the console frequently

shows the above annoying messages. NIL normal debug messages

for IPSec. Could any body help?

If I disabled all debug processes, everything is OK.

Re: Abnormal console display when IPSec/Isakmp debug is on

This is a known issue when you run IPSec on ethernet interfaces while running on IOS 12.2(11)T. This issue should be resolved in the later version of code, 12.2(13)T or alternatively, you can downgrade to 12.2(8)T5.
