Re: Anyone know what esp sequence fail means
If you have a CCO login you can put this command into the output
interpreter and it will tell you why you have received this error and
what you can do about. I run this output through and got some good
stuff. I don't think I can post it here.
The jist of the error is that a packet arrived out of sequence and
(sometimes this is natural) other times it means you have QoS
reordering the packets before IPSec gets its hands on the packets and
the anti-replay feature of IPSec is dropping the packet.
