Sure. Everything is working fine. I am just trying to validate those errors. I want to be able to tell my boss what types of errors it is, even though it is not affecting the VPN traffic. Thanks

So there is no way to see the meaning of those errors, unless I monitor the connection or do some debug. Correct?

Yes that is correct. &nbsp;As John indicated you'll go nuts trying to decipher the messages.<br />

So I think you have all you need and you did not post any specific errors. So if that is all, please do not forget to close out the question. &nbsp;Thank you.

@bobon - Thanks much. And despite what was said above, it is worth your while, in a spare moment, to look through packets just to see what is there.

Yes. I will have to be on site to setup Wireshark for the monitoring. IT is too bad you can see the errors but we don't know what it is until we look into the packets. I don't have a lot of experience with VPN. So if I look at those errors numbers, I will assume that something is wrong with the connection. But like you mentioned it may just be retransmissions.

I have 4 site-to-site vpn with Cisco routers without ASA firewall. When I did the show crypto ipsec sa, I see send errors and recv errors. What are those errors? Can I see the meaning of those errors somewhere? Thanks

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Encryption is the process of encoding messages or information in such a way that only authorized parties can read it. In an encryption scheme, the intended communication information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients, but not to unauthorized interceptors.
